| GENERA. ES Ab gt o N. G KINDBI PREFACE. The present treatise is an introduction to a synopti- cal Moss-Flora of Europe and N. America, ready as manuscript. lt is an essay to define all here belonging genera of Bryinee and to dispose themselves in natural families with attention also to exotic genera and species. To clear their natural affinity I have often found that the com- mon habit (»habitus») of the plants indicates the place in the system; it is also a »criterium« not to depreciate. To state »a priori» the vegetable organs, of which . the characters are to be chosen, does not agree with | nature, There are to be found in a certain genus constant characters, which in another are very variable. »Cha- racter non dabit speciem, sed species characterem». . Recent bryologists have attached too great an im- portance to the organisation of the peristome. The exo- stome (the outer or the simple peristome) is in many genera, also in individuals, variable. The endostome of — the capsule gives indeed good constant characters also E m in. Tr by the author examined genera and species. 1 E^ neglected.

The author was borne his MR Mode. in me Oo iality pe = 4 I have made longer travels for this purpose also in Norway (9 summers in the alpine district), in the Pyrenees 1855, in northern Italy 1888, in the Switzerland 1888, 1889, 1892 and 1895, also several times in Germany. My collections have been augmented by contributions from many bryologists. Many typical specimens, collected by Austin, Berggren, Bottini, Breidler, Brotherus, Cardot, Drummond, Hartman, Howe, James, Lesquereux, Levier, Lindberg, Lorentz, Milde, Philibert, Renauld, Roell, Schim- per, Sullivant, Venturi, Zetterstedt and others, have been very useful. I have also received larger collections by D:r C. Mueller (mostly exotic species), Mr J. Husnot (Musci Gallize), the Rev:d A. C. Waghorne (about 1,000 specimens from Labrador and N. Foundland) D:r V. F. Brotherus (mostly from Finland), D:r E. Levier (from Spain and Portugal), Mr J. M. Macoun (from Alaska), D:r T. Heldreich (from Greece), Prof. J. Arcangeli (from Italy), Messrs G. A. Holt and T. Rogers (from Britain) D:r R. Gyllencreutz (from Spetsbergen). : I wish therefore to thank sincerely my friends and correspondents for valuable assistance, especially D:r Mueller, which had the benevolence to examine the greater part of my new American species. (more than 200), and Prof. | . Macoun, having sent about 7,000 specimens, collected in — N. America in long travel: during many years. Haakooping Sweden : 12 Octob. 1896. -Section atylepidece.

Species of European and Northameriean bryines (Mosses) synoptieally deseribed by N. Conr. Kindberg. Part 1. Pleuroearpous ooe Iinköping, Linköpings Lithografiska Aktiebolag 1896. Preface. Since the publication of Schimpers Synopsis muscorum euro- peorum (1876) and Manual of the mosses of N. America by Lesquereux and James (1884), the bryology is enriched by many new species. Also several very important bryological manuals, viz. by. Boulay, Braithwaite, Husnot and Limpricht, have contri- contributed to a more complete knowledge of the mosses. The present treatise is an essay to revise and compare all hitherto known species and subspecies of Bryinez, found in Eu- rope and N. America. Excluded species are regarded as varieties or not sufficiently known. I believe that the greatest importance is to attache to the natural affinity of such species as could be joined to common types (subgenera or groups) Affinity is not to be defined through a few artificial characters, stated »a priori». It needs therefore to select characters, peculiar and constant to each genus. Some characters are in some genera variable, but in others constant. I have therefore not described selected specimens in all their parts but generally omitted such characters, as evidently are too variable. When some species are critical or hitherto not well-known, I have tried to propose all their necessary di- stinctive characters. To facilitate the determination of sterile specimens, so often occurring, I have accurately described the areolation of the lea- ves and the common habit of the vegetals. My descriptions are not transscribed from other authors but based on my own microscopical researches and studies in nature. I have therefore in Europe visited northern and southern districts and their different regions up to the glaciers and the perennial snow, also augmented my collections through contributions by many correspondents. The geographic distribution and the sta- tions of N. American mosses are accurately observed principally by Prof. J. Macoun, D:r J. Roell and the Rev:d A. C. Waghorne, also (in Greenland) by Prof. S. Berggren. | In some few cases, when I not have had occasion to exa mine specimens of a very rare species, I must cite the descri tions of their authors or describe the species following good drawings, viz. Icones muscorum by Sullivant. | About 1600 species and 340 subspecies are described in m manuscript. Common to Europe and N. America about 620 species. Peculiar to N.
