In the summer of 1886 I published for free distribution a key to the genera of mosses recognized in the Manual of Lesquereux and James. A large edition of that key was soon exhausted, and I have been frequently assured that it proved of real service to students of mosses. Although much misgiving was felt as to its accuracy very few changes have been found necessary, and it is now presented for the third time substantially as it was at the first, ex- cept for the changes involved in its extension to include the sub-genera of Hypnum, most of which, as given in the Manual referred to, are certainly of generic rank. Encouraged by the approval of the key to genera, in May, 1890, I published keys to the species of North Ameri- can mosses recognized by Lesquereux and James. These keys were printed in the eighth volume of the Transac tions of the Wisconsin Academy of Sciences, Arts and Let- ters, and a considerable edition of separates was also struck off. In those keys I included the comparatively small number of new species which had been described since the the issue of the Manual. The work made no pretensions to a critical study of North American mosses, but was de- signed only as a convenience for students. The new edition here presented is meant to serve the same purpose more fully. THE NEW EDITION. Three reasons have induced me to prepare a new edition. (1) The separate edition printed in 1890 was exhausted sev- ly BULLETIN OF THK UNIVERSITY OF WI800N8IN, eral years ago, and requests for copies of it were being re- ceived continually. (2) It will be several years before the new Manual of North American mosses can be com- pleted, and much information is needed to make critical study for that work possible. (3) A very large number of new species have been described since 1890, about which it is especially desirable to have more accurate information. I was fortunate in being able to associate with me in this work Mr. Fred D. Heald, sometime fellow in botany in the University of Wisconsin, who has prepared the first draft of the revision. Of some particular parts of the work for which credit is due him I shall speak later. COLLECTED DESCRIPTIONS. Comparatively few who would be glad to collect and study mosses have access to the various publications in which the species new to our flora have been described. We have thought it best, therefore, at the risk of adverse criticism, to append to the keys collected descriptions of all species not found in Lesquereux and James' Manual. For the specialist this may be looked upon as wasted energy; but these keys are prepared chiefly for amateurs, who will doubtless be glad to have these descriptions brought to hand. The source of the descriptions reprinted in the Appendix is always cited. The descriptions are not always the orig- inal ones, though generally they are if the species is one recently named. We have not thought it necessary in other cases even to cite the original description which can be found readily from the clue given. KINDBERG'S NEW SPECIES. A great number of new species have been described by Dr. N. C. Kindberg, of LinkOping, Sweden, and by Dr. C. MftUer, of Halle, in collaboration with Kindberg, from the collections brought together by John Macoun, botanist of . ^ ^ . - ■„ . p.j^ ^ ..-^j;'|-- ^ ^^.^-^ UN, )re being re- s before the m be com- lake critical e number of about which information, th me in this otany in the le first draft tie work for collect and jlications in 1 described. c of adverse icriptions of les' Manual, a as wasted >r amateurs, descriptions le Appendix .ys the orig- 3cies is one ary in other hich can be escribed by id by Dr. C. •g, from the , botanist of BARNES — NORTn AMERICAN MOSSES. T the Dominion of Canada. There is good reason to believe that a majority of these are not well founded. It is, of course, true that species as such do not exist in nature, and, therefore, that there will be diverse judgments as, to what individuals should be grouped to form a species. But there is a general agreement that changes induced by the immediate action of the environment upon the individ- ual can not furnish a proper basis for specific distinctions. Many o£ Kindberg's species are established upon such slight differences in size, shape or habit as may readily be induced by the immediate action of deficient or excessive moisture, light or shade, etc. Other species are based upon wholly insufficient material. When immature or barren specimc" * if Barbula and Bryum are described as new species, one w'. knows the remark- able variability of the vegetative parts oi plants can not but doubt the value of distinctin basr to overthrow varieties, but it lateurs keep in eek to bring to his problem, so ined. To facil- )ns of varieties arietal descrip- tated, are with BARNES — NORTH AMERICAN MOSSES. VU I the making of have therefore I Cardot's Musci 3 upon that list ) the nomencla- in neither the 1892 and 20: 1-32. Qost unfortunately, • present names nor the autonomy can be maintained. But it enables us to avoid constructing new names in this pub- lication, so that it need not be cited in the future litera- ture of taxonomy. This list also saved us much labor of compilation, both of names and of geographical distribution. Only such changes were made in the species included as seemed warranted by the special studies before mentioned. To the species therein enumerated we have added those described since its publication up to January 1, 1896. We have departed from this list and published mono- graphs in only two genera. In Dicranum we have used the results of the study of Barnes and True, and in Am- blystegium those of Cheney (both at present unpublished), so far as the omission of certain species of these genera is concerned. We have not included some new species yet in MSS., believing that this bulletin is not a suitable pi ice for publishing them. It is scarcely necessary to add that no attention has been paid to nomina nuda. CITATIONS. For the sake of brevity we have cited Macoun's Catalogue of Canadian Plants, Part VI. Mosses, by Macoun and Kindberg, simply as Mac. Cat. , to which its independent paging lends itself. Likewise RabenhorsVs Kryptogamen- Flora von Deutsch- land, CEsterreich und der Schtoeiz, Part IV. Die Laubmoose, by Limpricht, is cited as Limpr. Laubm. Other citations are given in full or with abbreviated accurate titles. In all cases we have cited the original publication of Renauld and Cardot's Musci Americce Septentrionulis in the Revue Bryologique. ACKNOWLEDGMENTS.

Perhaps his most diflftcult task was in preparing the new part of the key to the genera of Hypnaceae, and the keys to the species of Eypnum. The incorporation of the many new species in the keys to the larger genera, such as Sphagnum, Barbula, Orimmia and Bryum, was also a difficult task, made doubly difficult by im- perfect descriptions and want of figures. There is scarcely a key which he has not altered more or less to permit these insertions, and some are completely rearranged. In this work advantage has been freely taken of the suggestions, and sometimes of the very characters, in the keys found in Limpricht's Laubmoose, Braithwaite's British Moss Flora, Husnot's Mvscologia Oallica, and Warnstorf 's Char- acteristikund Vebersichtdernord-, mittel-, und sudamerikanischen Torfmoose. For the key of Dicranum thanks are due to Professor R. H. True and for that of Amblystegium to Professor L. S. Cheney, both of the University of Wisconsin. The first draft of the manuscript prepared by Mr. Heald I have carefully edited, revised, and, in some parts, re- ar- ranged. In the absence of Mr. Heald from the country, the not inconsiderable labor of attending to the details of publication has fallen upon me. For corrections to the previous edition acknowledgments are due to Mrs. E. G. Britton, Miss Clara E. Cummings, Mr. E. A. Rau, Dr. C. W. Swan, Mr. Marshall A. Howe, Mr. Edo Claassen, Professor L. S. Cheney and Professor R. H. True. The unfailing kindness of Mrs. E. G. Britton in supply- ing specimens, information as to particular species, and copies of several inaccessible descriptions receives also our grateful recognition. Professor Conway MacMillan has also put us under ob- ligations by the loan of periodicals not accessible here.

The first three orders each have a single genus only. To the genera of the fourth order, Bryales, the key upon the fol- lowing twelve pages is devoted. In this key thre are always at least two choices pre- sented, whose equivalence is indicated by similar numbers or signs preceding the line, or by equal indention o! the lines, which usually begin with the same word or its op- posite. When the second member does not follow on the same page a reference to the page upon which it does oc- cur follows the first. For an example see page 158. When there are more than two choices offered, all except the first and last are followed by a number or sign to indicate that a succeeding one is to be sought. For an example see page 160. When the accepted choice is followed by a dotted line leading to the name of a genus, the description of that genus will be found in Lesquereux and James' Manual of the Mosses of North America on the page indicated by Arabic figures of ordinary face (999). The key to the species of that genus will be found on the page of this work indi- cated by the bold face figures (999) following. If the genus be not described in the Manual it will be found described in the Appendix, on the page indicated by italic figures (999.) In the keys to species the correlative choices are indi- cated in the same way. Arabic figures (999) following the name of a species show that the species will be found de • scribed in the Manual on the page named. If followed by italic figures (999), a description will be found in the Ap- pendix on the page indicated. APOLOGIA PRO LAHORE SUO.

Yet in another it is vital. It is in itself of only temporary value. It perishes with the using. The user may soon get beyond the need of a crutch. The only justification for such work ia its usefulness to amateurs, who may by its help put bryologists in posses- sion of facts regarding the distribution, variation, and re- lationships of our moss flora which could not be gained without their aid. These keys are published, therefore, purely as an encouragement to the study of our mosses.' which with the Hepatic^ are more neglected than any other group of which we have accessible descriptions. An earnest student equipped with patience, some skill in dissection, a compound microscope, and the Manual, ought to be able with the assistance of these keys to determine the names of most of the mosses which he can collect. Those which remain uncertain he can refer to those who possess the illustrations and exsiccati which are often in- dispensable for identification. Charles R. Barnes.
