In continuance of his studies in the Annonaceae, the writer finds that the silky annona of French Guiana (Annona sericea Dunal) is the type of a natural subgroup of the genus Annona, which should be segregated as a section. Tlxis will be composed of at least ten species, several of which have not hitherto received names. In addition to defining the section and characterizing the species, it has been possible in this paper to present photographs of a number of the type specimens, including that of Annona echinata and the flower of A. sericea, described and figured by Dunal in his classical mono- graph of the Annonaceae. For the photographs of the latter, the types of which are in the De Candolle Prodromus Herbarium, the writer is indebted to M. Augustin de Candolle. For that of A. trini- tensis he is indebted to the Director of the Royal Gardens at Kew. The remainder of the photographs, including those of A. spraguei, A. holosericea, and A. jamaicensis were taken in Washington under the writer's direction. The accompanying drawings were made by Mr. A. B. Boettcher and Mr. J. M. Shull, those of the essential parts being reproduced from camera lucida drawings of the writer. SYSTEMATIC TREATMENT. The species here described form a fairly well-defined genus sec- tion, for which the name Pilannona is proposed, to give it coordi- nate rank with the sections Eu annona (based upon Annona muricata L.), Atta (including Annona squamosa, A. cherimola, and their allies), llama (based upon A. diversifolia Safford), Annonella (based upon A. globiflora Schlecht.), 1 and Chelonocarpus (based upon A, scleroderma Safford). 2 As in other natural plant groups there are 1 See Safford, W. E. The Genus Annona: The Derivation of its Name and its Taxonomic subdivisions. Journ. Washington Acad. Sci. 1: 118. 1911. 2 See Journ. Washington Acad. Sci. 3:103-109. 1913. 263 264 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. certain species which appear to ^orm connections with allied groups, so in the section Pilannona the tj r pe species, A. sericea Dunal, appears to be allied to the 6-petaled A. pdludosa Aubl. and sometimes has 3 imperfectly developed inner petals; while, at the opposite end of the series, A. jamaicensis Sprague approaches A. cherimola, belonging to the section Atta. Notwithstanding these connecting links, the group may be regarded as sufficiently distinct, and the species composing it are most conveniently set apart for study as a section by themselves. The section may be characterized as follows: ANNONA, section PILANNONA Safford. Flowers normally 3-petaled, spheroid or rarely oblong in bud, the petals valvate, thick, concave, and not keeled within nor triquetrous; receptacle convex, often clothed with short fine straight bristle-like hairs; stamens numerous, with the connec- tive expanded into a terminal head above the two parallel pollen sacs, the surface of the head being either minutely papillose or echinate, and in some cases bearing a number of erect or slightly curved hairs; carpels numerous, crowded, more or less covered with sericeous hairs, with club-shaped styles and minutely tuberculate or echinate ovoid stigmas. As compared with the common custard apples of commerce (Annona reticulata, A. cherimola, and their allies), the fruits of this group are small, in many cases no larger than a plum or peach and sometimes the size of a strawberry. In nearly all the spe- cies the surface of the fruit is velvety, especially during the early stages, and the seeds are surrounded by scant pulp. As the name indicates, the young growth of the type species and its close allies is sericeous or velvety, and the leaves of most of the species are more or less velvety or sericeous, at least on the lower surface. In a few cases they become glabrate at length. KEY TO THE SPECIES.

SILKY ANNONA OP FRENCH GUIANA. Anona sericea Dunal, Monogr. Anon. 69. pi. 5. 1817. A small tree; young branches slender, clothed at first with soft ferrugineous or dark red silky hairs; leaves distichous; petioles short (4 to 8 mm. long), ferrugineous-seri- ceous; upper leaves on flowering branches longer and relatively narrower than those near the base, oblong to oblong-lanceolate or obovate-oblong, 10.5 to 18 cm. long and 3.5 to 5.5 cm. broad, acute or acuminate at the apex, short-acute or rounded at the base, membranaceous, finely and densely pellucid-punctulate, glabrate above with impressed midrib and inconspicuous lateral nerves (18 to 25 on each side), subtomentose beneath, the prominent midrib and slightly curved parallel nerves clothed with dark red or maroon silky hairs; lower leaves on the flowering branches ovate or elliptical, often obtuse or emarginate as in many other Annonaceae; flowers normally 3-petaled, globose in bud; peduncles solitary or sometimes in pairs, extra-axillary, straight, 11 to 16 mm. long, 1-flowered, appressed ferrugineous pubescent, with a minute caducous tomentose scale at the base and an inconspicuous bracteole near the middle ; unopened flower buds 10 to 12 mm. in diameter; calyx gamosepalous, 3-lobed, the lobes broadly triangular-ovate, abruptly acuminate or cuspidate, clothed on the outside with appressed dark red hairs; petals broadly ovate or suborbicular (12 to 16 mm. long and 10 to 12 mm. broad), obtuse, thick, valvate, concave, clothed on the outside with fine ferrugineous-sericeous pubescence and on the inside with golden brown or pale ful- vous tomentulum; torus 6 mm. in diameter, convex, clothed with straight yellowish diaphanous caducous hairs and bearing numerous crowded stamens 1.8 to 2.2 mm. long; filaments very short, flat; pollen sacs linear, parallel, 1.5 to 1.7 mm. long, pale straw-colored, the connective expanded above them into a hood-like covering, yel- lowish, finely papillose, covered with minute points and bearing a number of erect stiff 266 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. sharp whitish diaphanous hairs; carpels together with the styles about as long as the stamens, the ovaries rufous-sericeous, the styles club-shaped, chocolate brown, micro- scopically granular on the surface, the terminal stigmas swollen at the time of polli- nation and minutely tuberculate; fruit (immature specimen collected by Poiteau) ovoid or heart-shaped, muricate with sharp fleshy points, like a minature fruit of A. murieata in appearance, 2.5 cm. long, 1.8 cm. in diameter; seeds small, ovoid, somewhat compressed and bearing a swollen caruncle at the base.

Annona sericea, though normally 3-petaled, has sometimes 3 additional inner petals. These when present are linear-lanceolate in shape and are sometimes imperfect, as in abnormal flowers of A. globiflora. They are alternate with the 3 outer petals and appear to close the seams between them, as if to protect the essential parts of the flower from moisture, as in the case of A. angustifolia Huber, a closely allied shrub of Brazil, regarded by Martius as a narrow-leaved variety of A. sericea (A. sericea var. angustifolia Mart.). 2 These 6-petaled forms appear to connect A. sericea with A. paludosa Aubl., in which the flowers are normally 6-petaled. Annona paludosa further resembles A. sericea in the soft, velvety lining of its leaves and its small, ovoid fruit covered with fleshy prickles, very much like the fruit collected by Poiteau in French Guiana (fig. 42). 3 The two species are undoubtedly distinct, both of them being recorded as common in French Guiana, where they are known by the common name guimame. According to Sagot A. sericea is distinguished from. A. paludosa as guimame savane. The latter is known simply as guimame, or as corossol sauvage (from the resemblance of its fruit to a miniature soursop). 4 1 Patris, J. B.

His collection, which probably included twelve or fifteen hundred species, and which has been estimated at two thou- sand, on account of duplicates, was presented by the chevalier Turgot to Lhe'ritier and was acquired by A. P. de Candolle, when he purchased Lhe'ritier's herbarium Patris's plants, which form more than half the Guiana species of the original herbarium of the Prodromus, bear neither the signature of Patris nor a record of the exact locality in which they were collected. Patris was in communication with de Rohr and Ro- lander. His specimens were prepared with great care, and were probably represented by either a single sheet or by two or three .

It is, however, to be found in the Systema. 1 The type is in an excellent state of preservation, and the drawing of it here presented (pi. 86) proves that Dunal 's figure is fairly accurate, showing the flower to be extra-axillary, though he erroneously describes it as axillary, and the peduncles possibly to have been geminate, as shown in plate 85. He does not, however, figure the details of the essential parts of the flower, a deficiency supplied in plate 86. The flower of the type itself (see pi. 91, A), kindly lent for the occasion by M. Augustin de Candolle, is in excellent condition and has not the least appearance of being, as it actually is, more than a century old. In this type specimen the carpels and stamens are cemented in place by the glue-like exudation from the stigmas, to which some of the pollen grains still adhere. The type plant collected by Patris formed part of Lhritier's herbarium. 2 In another specimen of the same collection (pi. 85) and bearing a similar label the peduncles are geminate. The leaves are exactly similar to those of the type speci- men, the lower surface of the young ones being covered with reddish silky hairs, while the older ones are subtomentose beneath and of an olivaceous color between the nerves, sharply contrasting with the bright reddish silky-tomentose midrib and lateral nerves. Annona sericea is represented in Brazil by a narrow-leaved form, A, angustifolia Huber, to which reference has already been made. A broad-leaved ally on the Island of Trinidad, which was included by Sprague in A. sericea, is below segregated as A. trinitensis. EXPLANATION OP PLATES 85, 86.

Annona holosericea is distinguished from all its congeners by its orbicular leaves and its velvety essential parts, of which both the connectives of the stamens and the outer stigmas (before becoming cemented together at the time of pollination) are con- spicuously hairy, as seen under the lens. The connectives differ from those of the stamens of A. sericea and its close allies in being covered with very many fine hairs instead of comparatively few coarse ones, and the stigmas resemble miniature echinate burs instead of being covered with rounded tubercles as in the species referred to.

Williams, April, 1908, flowers, fruit and leaves, "A tree 50 feet high, with a trunk 14 inches in diameter." To this species should probably be referred Sutton Hayes's no. 127, collected at Obispo Falls, near Barbacoas, Isthmus of Panama, cited by Hemsley as "Anona sp. ('iAnonae sericeae, var. foliis pedalibus)," 1 and described by T. A. Sprague under the name Anona uncinata? The latter name is unavailable, having been previously used by Lamarck. 3 If Hayes's plant, which I have not had the opportunity of comparing with the material upon which the present species is based, proves to be identical with the latter, it must assume the new specific name. The leaves of Hayes's plant are considerably larger than those of the material exam- ined, and a photograph of the fruit in the Kew Herbarium shows it to differ from that of Williams's specimen in the New York Botanical Garden in being ovoid-globose instead of spheroid and in having the claw-like tips of the carpels directed toward the peduncle instead of away from it, as in the latter (fig. 43). Annona spraguei is named in honor of Mr. Thomas Archibald Sprague, of the Royal Botanic Gardens, Kew, by whom Dr. Hayes's plant was described, as a tribute to his valuable work in botanical taxonomy.

(PLATES 95, 96.) Type in the Prodromus Herbarium of De Candolle at Geneva (ex Herb. Lhe'ritier), collected about 1795 at "Cayenne" (French Guiana) by J. B. Patris. DISTRIBUTION: Guiana and probably Brazil. SPECIMENS EXAMINED: FRENCH GUIANA "Cayenne," Patris, type collection, leaf, stamens, and tip of carpel; Mana, Sagot 6, leaf and stamens, from Kew Herbarium. This species is undoubtedly closely related to A. sericea Dunal, but differs conspicu- ously from that species in the character of the indumentof the leaves and tlie absence of hairs on the swollen terminal head of the connective of the stamens. Its ovoid, echinate fruits resemble miniature soiirsops (A. muricata L.). The recurved carpel tips are somewhat like those of A. cercocarpa described above, but differ from them in their less length and in their much finer, appressed pubescence, the carpels of A. cercocarpa being prolonged into tail-like appendages covered with relatively coarse, etrigose hairs (fig. 44). The present species is also sharply distinct from the preceding in the shape and texture of its leaves, as indicated by the accompanying illustrations. EXPLANATION OF PLATES 95, 96.

SPECIMENS EXAMINED: JAMAICA Without definite locality, 1849-50, Alexander Prior, in Gray Herbarium (with ovoid flower bud); roadside near Hampton, Santa Cruz Mountains, alt. 700 meters, September 4, 5, 1907, N. L. Britton 1196, in herb. New York Botanical Garden (with almost mature fruit) ; Sheldon Road, St. Andrew, alt. 750 meters, September 10, 1897, William Harris, 6861, in U. S. National Herba- rium (with fully developed flower and fruit). Annona jamaicensis has been known hitherto from specimens in which the flowers were evidently immature. The petals were described by Sprague as ovate, obtuse, 11 to 12 mm. long and 8 mm. broad. The accompanying drawing (pi. 99) shows them to be longer and relatively narrower when fully developed, approaching the shape of the petals of A. cherimola and its allies, but distinguished from them in not being triquetrous or keeled on the inner face. Moreover, the connective of the sta- mens is not so much swollen as in the section to which those species belong; and the incurved tips of the mature carpels serve also to prevent the confusion of this species with A. cherimola Mill., which is sometimes cultivated in the mountains of Jamaica. The flower buds somewhat resemble those of A. sericea when immature, but the indument of the petals in the present species is more velvety and of a more reddish color, while the stamens never bear hairs on the connective terminal. In addition to these points of difference the leaves are relatively broader and are never clothed with the dark red, soft, velvety lining of the leaves of A. sericea and its close allies.
