EDITOR'S PREFACE.
Whilst the sheet which terminates at page 48 was passing through the
press, Sir W. Hooker's long career of botanical authorship was somewhat
unexpectedly terminated by his death. This is not the place to enlarge
upon the services which in many ditferent ways he rendered to botanical
science, or to do more than allude to the regret which will be felt by many
who had waited for this long-planned work, that he was not spared to
complete it. I need only say that having been honoured by Dr. Hooker
with the request that I should carry it out, and having been entrusted by
him with the manuscript notes prepared by his father, and the copy of the
" Species Filicum " annotated in contemplation of this work, and having
had full access to the specimens from which the descriptions in the
" Species Filicum " were made, I have done my best to carry out this
" Synopsis " to a conclusion in strict accordance with the original plan.
The principal collection which we have received at Kew since the original
preface was written is a beautiful series of the ferns of New Granada,
gathered by MM. Lindig and Triana, for which we have to thank the
authorities of the Paris Museum. This contained a considerable number
of new species, which were described by Professor Mettenins, whose loss
in the prime of life we have also had to deplore since the work was
commenced. For other novelties we have also to thank Lady Barkly,
Dr. Thwaites, and Mrs. Lyell. Partly in consequence of these additions,
we have been obliged to extend the work to ten parts instead of nine,
as was planned originally. The total number of species admitted and
described is 2,235.
A paper by myself, containing a summary of the leading features of
fern-geography, based upon this work, will appear in the part for 1868
(vol. xxvi. part i.) of the " Transactions of the Linnean Society."

PREFACE.
The Author, having recently completed his " Species Filicum," * now
offers to the public a " Synopsis of all known Ferns," which contains, besides
brief diagnoses of the species described more in detail in that work, together
with their geographical distribution as far as yet ascertained, such additions
and corrections as have come to his knowledge, together with an account
of the Sub-Orders OsMUNDACEiE, Schizjeace^, Marattiace^, and Ophio-
GLOSSACE.E. He does not, however, pi-opose to include the Lycopodiacece,
Salviniacece, Marsileacece,, Isoetacece, and Fquiseiacece, which differ much
from these, and it may be said from each other, and which have of late
engaged the study of several able monographers. He farther intends to
depart from the scope of the " Species Filicum " in another point, which
requires a few words of explanation.
In the Introduction to the " Species Filicum," the Author stated that he
had included in that work a considerable number of impei'fectly described
species, of which he had seen neither specimens nor figures, solely because
they had been proposed by authors of reputation. These he now thinks
it desirable to omit. No doubt many are described under different names ;
of others there is no prospect of anything further being known ; and of
all the characters are so vague, or imperfect, or pi'olix, that it is impossible
to define them by brief diagnostic characters, such as alone are suited to
the pages of a Synoj)sis.
After upwards of half a century, more or less continuously passed in the
study of Ferns in the richest Herbarium of that Order in the world (his
own), and latterly with the aid of the finest in cultivation (that of the
Eoyal Gardens of Kew) ;t and after the devotion of fully half that number
* In 5 vols. 8vo, with 300 plates representing upwards of 500 species.
+ The formation of this fine collection is mainly due to the exertions and ability of
Mr. John Smith, who for forty-three years held an important position among the officers
of the Royal Gardens. His knowledge of Ferns, and his writings upon them, justly
entitle him to rank among the most distiuguished Pteridologists of the present day.
4 PREFACE.
of years to the preparation and publication of the " Species Filicum " and
other works on the same subject, the Author feels satisfied that these
doubtful and imperfectly described species form the greatest obstacle to
any satisfactory advance in descriptive Pteridology.* He may, indeed, point
with satisfaction to the fact, that before he undertook his work their
number was many times greater than that still cumbering the volumes. But
there is little satisfaction in the reflection that for the identification of a
great majority the Author is indebted more to some happy accident, to the
possession of copious and varying suites of specimens, or to circumstances
connected with the history or locality of the species, than to their published
descriptions or to scientific evidence.
There have been two fruitful sources of these " bad species " : — the first,
the idea that geographical limits must limit the dispersion of species ; the
second, that any single chai'acteristic, however minute, if only either con-
stant or prevalent in a given area, is of specific value. Such arbitrary
conclusions have led to the well-known Osmunda regalis receiving different
names in many different countries, and to the forms of our Aspidium
{Polystichum) aculeatum having even moi'e names in our own country, and
still others in exotic regions. The errors arising from the first are corrected
as rapidly as botanical and geographical discoveries advance together ; but
it is not so with those due to the second source, for the difficulty of limiting
tliese variable species is so great, that it often becomes impossible to frame
such diagnoses as shall include all the varieties of one species, and exclude
the varieties of another closely allied species. In all these cases we must
trust to time and experience to test our conclusions ; and such difficulties
should teach us to look with indulgence on the views of those who differ in
opinion from ourselves.
The same remarks apply to the genera as to the species of Ferns ; the
former having been, in the Author's opinion, unnecessarily multiplied. It
* In connection with Fern history, Mr. Thomas Moore undertook the publication of
an extremely useful work under the title of " Index Filicum," to consist of a Synojjsis,
with characters of the genera, and an enumeratioQ of the species of Ferns, with
synonyms, references, &c. &c., accompanied by excellent outline figures of the genera.
It is compiled with great industry and ability, and enumerates in an alphabetical
arrangement of the genera, ir^iva Acroplwrus to Goniophlehium inclusive, 1,730 species of
true Ferns. The list of synonyms, both of genera and species, shows at a glance how
much Pteridologists have been at variance on these points. The species enumerated
in our "Species Filicum" amount to 2,-101 ; according to Mr. Mooi'e, the number of
known Ferns would be 2,782.
PREFACE. O
is the case here as with other scieatiQc systems : those are the best cha-
racters which lead to a knowledge of the object sought for in the nearest
and clearest way, keeping in view also as much as possible its natural
affinities. The difficulties certainly are greater in the cryptogams than
among the flowering plants, because their characters are fewer, and the
forms of their organs more variable as regards size and shape.
In regai'd to the genera, the publisher has judiciously desired that nine
plates should be devoted to their illustration. They are all drawn from
nature by the talented Mr. Fitch, F.L.S., and on the same plan as the
plates of Ferns in Hooker and Arnott's late editions of the " British
Flora."
References are given to the volumes and pages of the " Species Filicum "
for fuller characters of the genera and species, as well as for figures, more
precise localities, and more copious observations ; and it is hojied that
the present volume will form a useful vade-mecum for the travelling
botanist and the cultivator of Ferns, and for ready consultation in the
Herbarium.
The Author cannot close these introductory remarks without expressing
his acknowledgments to numerous friends and correspondents for their
valuable communications of specimens (often accompanied by notes) from
various parts of the world. Many of these are recorded under their habitats
(or localities) in his former woi'k ; and a repetition of them would be out of
place in this. But space must still be found for the names of those persons
to whom we ai-e indebted for the discovery of any new species, or any new
or interesting locality in connection with the geographical distribution of
plants.
The commencement of the Author's formation of a Fern-Herbarium
dates as far back as 1811, with the corresj)ondence of the illustrious Swartz,
only four years after the publication of his invaluable " Synopsis Filicum ; "
a model for futui'e woi'ks of the kind. It is, however, from comjjaratively
new and distant regions, which have been within the last half century so
extensively explored by our men of science, that the most important collec-
tions have been derived, and to these botanists and travellers he is anxious
thus to express his obligations : —

Hab. Tropical and subtropical regions, almost universal, in the New and in the Old

of its section, so is G. dichotoma of the present one. Besides being most extensively
geographically distributed, it is very variable in the size of tlie i)innfe and in the shape
of the segments, and in being more or less glabrous or densely tonientose beneath, green
or glaucous, and very variable in the texture of the frond : but the pairs of accessory
pinnas at the base of a fork are invariably present. There are also abnormal or
aberrant forms. Among them I have specimens with lobes of the pinnae free (pin-
nules), and more or less deeply pinnatifid, from Penang and Java. I have others from
Java, which Mettenius (Ann. Mus. Bot. L. Bat.) calls var. ulttrnans, in which the
primary divisions of the stipes are scarcely dichotomous, but alternate, " frondes
inaequaliter dichotonise."— In regard to size, some of the pinuffi are 1-1, > ft. 1., and some
are 6 in. br. Occasionally, the lowest pair of lobes is much elongated, reflected, and
pinnatifid.

1 have again examined with great care the two states of this plant, and am only the
more confirmed in my opinion that they constitute but one species.
* The three preceding species are readily enough distinguished by the undivided or
simply pinnated structure of the frond, combined with other peculiarities : but it is far
otherwise with those which follow, whose fronds are more compoundly divided, which
])resent a much greater similarity one with another, and of which, on account of their
frequently gigantic size, we rarely receive other than mere fragments, telling nothing
of their arborescent trunks or caudices, and rarely of their stipites, which often present
useful characters. I am unable to offer any better sections or subdivisions than according
to the countries they inhabit.

W. Indian Fern, by which he probably intends Alsophila tenera, of J. Smith, which I
have placed among "species dubire," in Sp. Fil. p. 49. But the original specimens are
very imperfect ; and, unless better known to Dr. Griesebach than to me, I should doubt
the correctness of its being identical with Hemitdia nudtijtora, Br. ; the latter, I believe,

Hymenophyllmn is the late Dr. Van den Bosch, whose magnum opus, the " Hymeno-
pbyllacere JavanicEe," contains engravings of many of the specie.^i, which, in point of beauty
and delicacy of execution, have rarely been equalled. But his views, and their practical
carrying out with regard to the limitation of genera and species, were the very opposite
of those of Sir William Hooker, as may be judged from the fact that in his Synopsis and
Supplement, 450 so-called species are given, and that out of what are here considered
two genera, he makes twenty-four. Upon this point Sir William Hooker wrote : " This
genus and the following one have had their species multiplied to an extent with which I
canuot at all concur. The late learned Dr. Van den Bosch, in his widely-scattei-ed publi-
cations, has no doubt described many new species, which it has not been in my power to
identify ; but having been favoured with his opinion on a large portion of my collection,
I regret to be compelled to join with my friend Dr. Grisebach in the opinion expressed
in his 'Flora of the British West-Indian Islands,' that many of the species are not well
founded."

Hab. Regarding these two as British plants alone, we should pronounce them readily
separable by the characters given, which are taken from our two indigenous plants ; but,
looking abroad, we find them connected by every intermediate stage of gradation. Four-
teen species admitted or proposed by Van den Bosch cannot be clearly separated. To
our o belong his Tunbridrjcnse (Britain, Normandy, Corsica, Tyrol, Italy) ; Bref/cannm,
Presl (S. Africa) ; minimum, Richd. (Auckland Islands) ; antarcticum., Pr. (N. S. Wales
and V. D. Land) ; asperulum, Kunze (Chili) ; and Zeelandicum, V. D. B. (New Zealand).
Some of the Cape specimens are bipinnate, and have the lower pinnse fully 2 in. 1. A
plant from the Falkland Islands has the pinnaj only once forked, or even simple : a grows
also in the Mauritius, Madeira, the Azores, Jamaica, and Venezuela. To /3 belong

Hab. Java, Philippine Islands, Ceylon, and western slope of the Neilgherries. — Usu-
ally easily recognizable by its peculiar proliferous habit, but the fronds are very variable
in outline, and sometimes closely resemble the deeply-divided forms of section 3. T. diffu-
sum, Blume, and T. Teysmanni, V. D.B., are closely allied Javan plants, which I have
not seen. A plant collected by Barter at Sierra Leone is probably this species ; but it
is in a young state, and does not show the proliferous ramification. This sjiecies is cut
more deeply than the three pi-ecediug, and the segments are narrower.

Both vary much in division, but they are universally regarded as distinct. The best
character for this seems to be the presence of numerous intermediate spurious venules
between the veins proper, as in various species of Trichomanes. D. coniifolia is quite
intermediate between D. data and the type. I), patens, Swz. (Hk. Sp. Fil. 1. p. 167), must
probably also be referred here, and I). Jlaccida, J. Smith, is a tender finely-cut form.

Islands and Tropical Australia, Madagascar, Zambesi Land, Angola, Guinea, Cape
Verde Islands, Tropical America, from Mexico southward to the Organ Mountain s.^ —
An easily-recognizable and widely-diffused species. The two varieties are evidently
connected together by gradual intermediate stages. When the upper edge of the pinnae
is much lobed, the sori appear transversely oblong, but in some of the specimens the line
is quite continuous. A. PhiUppense, Linn., adopted from Petiver, though described by
Linnaeus as simple, is figured by Petiver as pinnate, and is doubtless this species.
4. A. Cantoniense, Hance ; st. slender, naked, polished, blackish, 2-3 in. 1. ;
fr. 4-6 in. 1., | in. br., simply pinnate with a terminal pinna, or prolonged and
rooting at the extremity ; pinnce in 3 to 5 distant opposite pairs, ^ in. br., |^-| in.
deep, suborbicular, nearly entire or slightly lobed, shortly stalked ; texture
pellucido-herbaceous ; rachis and surfaces naked ; sori few i-ound the outer edge,
not contiguous, roundish or transversely oblong.
t Except casually in A . macrophyllwn, lucidum, and perhaps some other species.
21. ADIANTUM, § EUADIANTUM. 115
Hab. Ramparts of Canton, Hance, 7542. — This much resembles A. tremulum; but the
petioles are shorter, and the lower pinnae opposite and round, not dimidiate.
5. A. caudatiim, Linn. ; st. 2-4 in. 1., tufted, wiry, spreading, dark chesnut-
lirown, tomentose ; fr. 0-12 in. 1., simply pinnate, often elongated and rooting at
the extremity ; pinnce ^-| in. 1., j in. deep, dimidiate, nearly sessile, the lower
line straight and horizontal, the upper rounded, more or less cut, often deeply
and repeatedly, the point usually blunt, the lower ones slightly stalked ; texture
coriaceous, the veins prominent, the rachis and both surfaces of the frond villose ;
sori roundish or transversely oblong on the edge of the lobes. — Hk. Sp. 2. p. 13.

Hab. Arabia Felix, Himalayas (3,000 ft.), and Hongkong, southward to Ceylon and
Java, Madagascar, Mauritius, Zambesi Land, Angola, banks of the Niger, and Cape
"Verde Islands. — A. soboliferum, Wallich (Hk. Sp. v. 2. t. 74. A.), appears to be a form
of this with winged petioles and stipes. A similar form of A. lunulatum has been
gathered by Drs. Kirk and Welwitsch in South Africa.
6. A. calcareum^ Gard. ; st. slender, filiform, 2-3 in. 1., polished, blackish,
naked ; fr. 4-6 in. 1., or prolonged and rooting at the extremity ; pinnm \-\
in. br., \ in. deep, varying in shape from a quarter to nearly half a circle, lobed
from the circumference towards the centre 2 or 8 times half the way down, and
the main lobes again cleft less deeply ; texture tliinly herbaceous ; rachis and
both surfaces naked ; sori roundish or transversely oblong, placed in small
depressions at the apex of the lobes. — Hk. Sp. 2. p. 15. Ic. PL t. 467.
Hab. Province of Goyaz, Brazil ; gathered by Mr, Gardner. — A more tender plant
than A. caudatum, which is not known in America, but not clearly distinct. A. rhizo-
phytum, Schrad., also from Brazil, is closely allied, or may be the same.
*^* Polj/sorotis group. — Fronds once or more pinnate, the fruit in numerous
roundish or oblong or transversely reniform marginal patches. Sp. 7-31.

fr. 6-12 in. L, 3-4 in. br., with a large terminal lol)e and 1 to 12 alternate jomwte
on each side, the lowest 2-3 in. ]., ^-1 in. br., cordate and auricled broadly at
the base aljove, roundly out away on the lower side, slightly stalked, and

Hab. Mexico and West Indies, southward to Brazil and Peru. — This and the next
are the only species of the group with a clearly-defined midrib.
8. A. obliquum, Willd. ; st. 3-6 in. 1., erect, Aviry, polished, blackish, slightly
pubescent ; fr. 0-12 in. 1., 2-4 in. br., with a terminal lobe and 3 to 12 pairs of

1-2 lin. \ir.—Hk. Sp. 2. p. 0. t. 79. A.
Hab. West Indian Islands, Columbia, and Guiana.— Very doubtfully distinct from
A. Kaulfussii. The characters relied upon are the thicker texture of this, its more con-
tinuous sori, and the absence of a glaucous tinge on the under side of the leaves. Grise-
bach refers the obscure A. dcnticulatum, Swartz, to this species.

Hab. Mexico, province of Oaxcaca, at an elevation of 3,000 ft., Galeotti, 6561. — Avery
distinct species, easily recognized by its large round equal-sided pinnules. The venation
is very clearly marked on the under side of the frond, but is quite flabellate, and there is
no central rib which is stronger than the others.
10. A. Pcruvianum, Klotzsch ; st. 6-9 in. 1., strong, erect, nearly black,
polished, naked ; fr. simply pinnate, or with 1-3 branches at the base, or even
with some of the latter again slightly branched ; pinnules 2 in. or more br.,

acuminated point, tinely toothed and lobed round the upper and outer edge, the
lowest on stalks ^-| in. 1. ; texture papyraceo-herbaceous ; rachis and both
surfaces naked ; sori in interrupted patches round the sides of the pinnules. —

Hab. Peru ; gathered by Mathews, and lately again by Spruce. — A very fine and
well-marked species, which the size and shape of its pinnules will readily distinguish in
the group.
11. A. svhcordatvm, Swartz ; st. 6-12 in. 1., strong, erect, blackish, naked,
polished ; fr. 1-2 ft. 1., 1 ft. br., deltoid, tripinnate ; lovjer pinnce deltoid, 1 ft. 1.,
6-9 in. br. ; scgm. about 2 in. 1., 1 in. br,, ovate-acuminate, equal at the base, or
the lower side obliquely truncate, slightly lobed, on stalks \-\ in. 1. ; texture

Hab. Guiana and Brazil. — This resembles in general habit A. trapeziforme, but differs
in the shape of the pinnules, which are equilateral or slightly oblique at the base on the
lower side.
12. A. intermedium, Swartz ; st. 6-12 in. 1., erect, strong, polished, but
somewhat tomentose ; fr. with a terminal pinna 6-9 in. 1., 2-3 in. br., and
1 to 3 small spreading lateral ones on each side ; pinnl. 1-1^ in. 1., j-| in. br.,
unequal-sided, but not dimidiate, the lower half being the smallest, about the
inner third being cut off, the point bluntish or acute, the inner edge nearly
parallel with the stem, the upper nearly straight, scarcely toothed ; texture
subcoriaceous ; rachis tomentose ; S07'i in interrupted marginal patches, 1-2 lin.
across, placed round the upper edge and outer two-thirds of the lower one. —
Hk. Sp.2. 2>. 25. A. iOvea.r\iin, Hadcli. A. triangulatum, A'ae^//".
Hab. Tropical America, from Mexico and the West Indies southward to Peru and Rio
Janeiro. — A widely-diffused and well-known species, distinguished from A. tetraphijllum
by the outer edge being often brought down so as to be parallel with the upper edge,
so that we have two opposite rows of sori instead of one at an acute angle with the
other.
ft Ultimate segments dimidiate, the stems naked and polished. Sp. 13-20.
13. A. Shcpherdi, Hk. ; st. 3-4 in. ]., naked, polished, blackish ; fr. 6-12 in. ].,
simply pinnate ; pinnce | in. br., J-^r deep, dimidiate, the lower line nearly
straight, the upper rounded and, like the two bluntly rounded sides, broadly
lobed, quite sessile and usually reflexed, so that the pinnules of the opposite sides
of the rachis are brouglit face to face, the inner quarter of the blade being
imbricated over the stem ; texture subcoriaceous ; rachis and both surfaces naked ;

round the outer edge. — Hk. Sp. 2. p. 9. t. 73. B.
Hab. Mexico, gathered originally by Mr. Bates in 1834 ; and fine specimens have
been received lately from Morelia from Mr, Glennie. — In the texture of the frond and
form of the sori this curious plant closely resembles A. Galeottianuni, but the stem is
quite simple, so far as we know, the form of the pinnules quite different, and the habit
is very peculiar.
14. A. sinuosum, Gard. ; st. 4-8 in. 1., erect, naked, polished, nearly black ;
ft: with a long terminal central pinna, 2-3 in. br., and 1 or 2 pairs of erecto-
patent branches at the base ; pinnl. l|-in. br., ^-| in. deep, the lower line obliquely
decurved, the upper irregularly rounded and deeply lobed, the lobes again
crenate, the lower ones on stalks J-^ in. 1. ; texture papyraceo-herbaceous ;
racMs and surfaces naked ; sori obreniform, placed in rounded sinuses of the
crenations of the lobes. — Hk. Sp. 2. p. 35. Ic. PL t. 504.
Hab. Brazil, Gardner, 3552, Bnrchell, 6752 ; and a similar plant has been gathered by
Prof. Jameson near Guyaquil. — This resembles most A. Capillus-veneris in the segments.
They come generally about halfway between the flabellato-cuneate and truly dimidiate
types of form, so that its position may be said to be about midway between that species
and A . trapeziforme.
15. A. diapliamim, Blume ; st. 4-8 in. 1., slender, erect, blackish, polished ;
fr. 4-8 in. 1,, 1 in. br., simply pinnate or with 1 to 3 branches at the base, which
are sometimes nearly as large as the terminal one ; pinnl. ^ in. br., j in. deep,
the lower line rather decurved, the upper nearly parallel with it, crenate like
the blunt outer edge ; texture thin ; rachis naked, surfaces nearly so ; sori

Hab. S. E. China, Aneiteum, Java, Fiji, New Caledonia, Norfolk Island, N. Zealand, N. S.
Wales. — This is nearest the next species, but is much less branched, and the pinnules are
thinner in texture. In habit it shows an approximation towards the pedate group. It
is not unlikely that A. erecfum, Kunze (Bot. Zeit. 1848, p. 211), is the same.
16. A. aji7ie, Willd. ; st. 6-9 in. 1., erect, polished, blackish, glossy ; fr. with a

which seems strikingly different from the normal form in habit, but resembles it closely
in other respects. In the shape and size of the pinnules this species is not strikingly

Hab. Gathered in an expedition fiom Western Texas to El Paso, New Mexico, October
1849, C. Wright, No. 816. — This difl'ers from C. tomentosa by being coated with distinct
scales instead of mere woolly hairs on the stipe, rachis, and midrib of the pinnse beneath,
and by being matted with tomentum on the upper surface. Gordon's Colorado plant is
perhaps the same, but is more slender and less distinctly scaly. We are indebted to
Prof. Eaton for the elucidation of the United States species of the genus.

Hab. Tropical America, from Venezuela along the Andes to Peru. — P. muricata, Hk.,
differs from j8 principally by its lower pinnje being conspicuously stalked at the base.
This species much resembles P. deflesca in general appearance, but may be known readily
by its muricated rachises. A muricated plant, gatheied by Dr. Spruce in the Central
Andes (Nos. 5707 and 5665), is probably distinct. The stipe is strong and distinctly
prickly, and is marked in one of the numbers as 5, and in the other as 12 feet in length.
One of the pinnte is 2 feet long, the largest pinnule 10 inches, and the largest ultimate
segment 1 inch long, 2 lines broad. The venation is fainter than in P. coriacea, and both

Hab. West Trojiical Africa, Mauritius, Bourbon, Hindostan (ascending in the Hima-

from the West Indies southward to Brazil. — This differs only from P. quadriaun'la in
the pinnae being less deeply pinnatifid, and the bases of the midribs of the segments being
connected by an arching vein. This arch springs normally from the bases of the midribs,
but sometimes begins and ends at points between them. It is sometimes triangular, but
sometimes very low, and in what Agardh considers as P. nemoralis, Willd., we have the
venation considered as characteristic of hianrita combined with the entirely free vena-
tion considered as characteristic of quadriaurita in one and the same frond, so that they
must be regarded as very doubtfully distinct. P. Galeotli, Fee ; P. amosna, Blume ;
P. aliovircns, Willd. ; and P. armata, Presl, are apparently allied plants ; and C. Kleini-
una, Presl, and C. Anamallayensis, Beddome, I cannot distinguish clearly.

scandent, with long spreading rigid branches, and is said to attain a length of 10 yards.
In a form gathered by Capt. Carmicliael in the island of Tristan d'Acunlia, the veins do
not anastomose at all ; often there is only a single arch on each side of the costa at the
base of a segment, and in specimens, otherwise quite similar, there is copious joining
towards the edge. Sometimes the sori are confined to the sinuses, as in Lonehitis.

but the Australian one has now been traced into a pinnate form, and the Polynesian
into a simple form in the fertile state, and in each case I cannot find any character to
distinguish these from the other supposed species. As in most of others, the fronds are
occasionally in part sterile and in part fertile. The pinnae are fewer and more distant
from one another than in any of the species that follow, and their decurrent base is
broader and more couspicuous.

Hab. Sandwich Islands and Sumatra. — A fine plant, which combines the habit of a
small Cyathea with the fructification of a Blechnum. The original S. pallida, H. & A.,
is a mere form with a paler rachis ; but a plant thus named by Mettenius, gathered by
Dr. Hillebrand, is less rigid in texture, with flatter, broader, and blunter pinnules, and
quite conspicuous venation. Probably this is Brackenridge's pallida, which is said to
have a somewhat paleaceous rachis ; and we have also another plant from Dr. Hillebrand

single lower pinna of this resembling a wliole frond of that. We cannot in any way dis-
tinguish the New Caledonian A. sororium, Mett., of which the trunk is not known, from
the less deeply lobed form of this, and have what appears to be the same from the Society
Islands.

\ The character furnished by the shape of the involucre divides the original Aspidium
into two unequal halves. The two genera tlius obtained have a closely similar range of
variation in cutting and venation, and it is by no means clear in which of the two several
species should be placed. It is perhaps scarcely needful to warn the young student to
bear constantly in mind that an Aspidium with an abortive or obliterated involucre is
not distinguishable from a Desmobryoid Polypodium. The number of species which have
been originally described as non-indusiate, in which a more or less (often very slightly)
developed involucre has been afterwards found to exist, is very considerable, and no doubt
more will be added to the list.

(Andes of Ecuador, 5210), agreeing with the small forms of this with uniserial sori in
habit and texture, has the sori usually terminal on a free veinlet in the costal areolte, as
in typical Gonwphlehium , but occasionally a short veinlet is carried from the centre of the
one that bears the sorus to the next above it, which springs from the midrib, as in
P. guatemahnse, and as represented in the figure by Mettenius of P. pleurosorum, Kze. ;
so that we have then a venation midway between ihat of Gonlophkbium and Phlebodium
proper.

Sori in continuous marginal or slightly intramarginal lines. A small genus,
almost entirely/ trojncal, with free veins and grass-like fronds of subcoriaceous
texture. It has considerable claim to be placed in the Involucrate series near Lind-
iai/a. The species are very difficult of discrimination, and we have admitted here
considerably fewer than M. Fee, who has published an elaborate illustrated mono-
graph of the genus, in which he relics to a large extent upon microscopic characters
{the shape of the spores and abortive capsules') to characterize them. Tab. VI.

Hab. Himalayas and Japan to Ceylon, Madagascar, Xew Caledonia, Queensland, and
Society Isles. — We cannot determine more than one clearly-marked species, but Presl
defines ten, and De Vriese sixty. There is a considerable range of variation in the tex-
ture of the pinnae and closeness of the veins and sori, and the number of capsules which
compose the latter ; and in many of the forms there is a free veinlet, which is very
variable in length and distinctness, which begins at the edge of the frond in the inter-
space between the veins proper. Psllodochea salicifolia, Presl, is an entirely obscure
plant, supposed to have been gathered in Lahore, said to be like Ancjiopteris, but without
an involucre.

Island.— The typical plant (Smith, Ic. inedit. t. 48 ; Beddome, t. 79) has pinnules 1-1 4
in. br., serrulate principally at the apex, numerous forked veins, and submarginal synan-
gia, with 10-12 caps, on each side. To this belong M. sorhifolia, Bory, and M. elegans,
Endl. From this we cannot separate clearly many plants which have been regarded as
distinct; of which the principal are i¥. salicifolia, Schrad. (KzS. t. 38), including M. Dre-
giana and natalensis, Presl (South Africa), pinnules sharply toothed throughout, often
only 5-| in', br., veins more distant, synangia with about 6 caps, on each side, not so
close or so near the edge ; 31. salicina, Sm., De Vriese, tab. 3. fig. 18 (Society Isles),

Hab. Shores of the Mediterranean, and as far north as Guernsey, Azores, Madeira,
Guinea Coast. — The European plant is developed in winter, whilst in Britain 0. vul-
gatinn is not mature till June. 0. gramineii^m, Willd., from North and Peninsular India,
is probably identical, and the same may be said of the Australian and New Zealand
0. gramineum, R. Br. The New Zealand 0. minimum, Colenso, is not more than 1 in.
high, with the barren segment 3 lin. 1. by half as broad ; and three closely-allied forma
have been gathered by Dr. Welwitsch in Angola, — 0. gomesianum, Welw., l-l^ in. 1.,
barren segm. near the base, ^-| in l.,j2 lin. br. ; 0. luso-africanum, Welw., 4 in. I., barren
segm. central, 1^ in. 1., 2 lin. br. ; and 0. graciUimum, Welw., 1^ in. 1., barren segm.
central, truly linear, acute, 1 in. or less 1., under 1 lin. br.
2. O. rubellum, Welw. MSS. ; rootstock slightly tuberous ; fr. 1-2 in. 1., the
sterile division placed very near the base, roundish, j in. each way, without a
haft, often adpressed to the surface of the ground, thick in texture, the veining
hidden ; fertile spike j-§ in. 1., the reddish peduncle |-1 in. 1. when fully
matured.

but smaller, with the barren segment sub-basal.
3. O. htdhosum, Michx. ; rootstock tuberous, |^-§ in. thick ; fr. 2-4 in. 1., the
sterile division placed considerably below the middle, ^-1 in. 1., \ in. br., ovate,
without a haft ; texture stouter than in 0. vulgatum, the midrib and veining
quite indistinct ; fertile spike \-^ in. 1., the peduncle 1^-2 in. wlien fully

from Prof. De Vriese agrees with the American plant.
4. O. nudicaule, L. fil. ; rootstock slightly tuberous ; fr. 2-4 in. 1., the sterile
division placed not far from the base, ^-1^ in. 1., j-^ in. br., ovate or oblong,
without a haft or with only a slight one, the texture thin but the veins not
distinct ; fertile spike \ in. 1., the peduncle often 2-3 in, 1., very slender. —

Hab. America from the Southern United States southward to Brazil ; New Caledonia,
Malaccas, Peninsular India, Guinea Coast, Angola. — Whether this be the original ?ji(c^i-
caule is not quite clear, but it is the plant figured under that name by Swartz and Kunze.
To the type belong 0. ypanemense. Mart. t. 73, 0. surinamense, Reich., and O.flavicaule,
Klotzsch, and probably 0. moluccanum, Schlecht. Kunze's fig. a, 0. Wightii, Hk. & Gr.,
and 0. cllipticum, Hk. & Gr. t. 40, are larger in size, with the sterile segment as thin
and the venation as plain as in redculatum, 2 in. or more 1., |-| in. br., and the stem
longer. 0. maci'orhizum, Kze. t. 29. fig. 1 (from Guiana and Brazil), is a much-reduced
variety, not more than l|-2 in. high, with the sterile division not more than 5 in. 1.,
\ in. br. The Sandwich Island 0. concinnum, Brack, t. 44, is most like this, but the
barren segment is farther from the base of the stem ; and this also appears to be the
case with the Chilian 0. melipillense, Reniy.
6. 0. vulgatum, L. ; rootstock not tuberous ; fr. 6-9 in. 1., the sterile division
generally placed about the middle, 2-4 in. 1., |-2 in. br., ovate or ovate-oblong

H,ab. Lapland to Japan and the Himalayas ; Azores, Guinea Coast, Angola, St. Helena,
Abj'ssinia, Cape Colony, IMascaren Isles, Australia, New Zealand, Sandwich Isles, Tem-
perate North America. — From the type 0. coriaceum, Hk., 0. elongatinn, R. Cunning, and
0. oratum, Borj', scarcely diverge at all. The Cape plant (0. capcnse, Schlecht.) has some-,
times, but not always, a more distinctly-marked midrib than the European one. The
Azorean 0. poly pJiy Hum, A. Br., is a small form with often several fronds from the same
root. 0. costatum, R. Br. (Hk. fil. FI. Tasm. t. 169), is also smaller, with the midrib
sometimes clearly marked. There is a tropical variety {0. pedunculosum, Desv., Kze.
p. 58. t. 29 ; 0. petiolatum, Hk. Ex. F. t. 56, and Blume) which occurs in Peninsular
India, Java, and Guiana, with the barren division like that of the type in form and size, but
thinner in texture, and with a distinct haft, which is not clearly separable from the large
foims of 0. nudicaule ; and near to this come 0. hrevipes, Beddome, t. 72, from the Neil-
gherries, with a stem under 1 in. 1., a peduncle 5-6 in. 1., very distinct areolation and
copious free veinlets ; and the Angolan and Guinean 0. ap)hrodisiacum, Welw. MSS.,
with a bulbous rootstock ^-f in. thick, and a distinct flattened midrib extending nearly
to the apex of the sterile segment.
G. 0. rcticulatum, L. ; rootstock not tuberous ; fr. 6-12 in. 1., the sterile division
placed about the middle, 2-3 in. 1., 1^-2 in. br., with a distinct haft and dis-
tinctly cordate basal lobes, the point blunt or subacute ; texture thin, the veins
distinct, usually no midrib ; fertile sjjike 1 in. or more 1., on a slender peduncle
2-4 in. 1., much overtopping the sterile segment. — Hk, & Gr. t. 20. Beddome,

as distinct both by Mettenius and Milde, is said to differ from Tricho-
manes by its conspicuously ribbed rachis, pinnse sessile from a broad
base, with a few adpressed linear and fibrillose scales on the under
surface, and broader scales destitute of a spurious nerve. — Vide Milde,
Fil. Eur. p. 69.

„ 213. Species 118*. A.lejndum, Presl, is said by Milde, Fil. Eur. p. 81,
to differ from fissum by its fimbriated, not creuate, involucre, and
thinner and glandular, not ebeneous, stem ; and he considers it a distinct
species.

„ 232. Species 214*. A. nicotiancefolium, Mett., has pinnse twice as broad as
\nflavescens, and is no doubt distinct. A. caucense, Karst., has more
distant veins, thinner texture, and pinnae slightly toothed, and is most
likely also a distinct species.
