TWENTY-SEVENTH ANNUAL MEETING. 153 



1849 first propounded and explained the alternation of generation in his 

 splendid book, "Die Entschung des Embryos der Phanerogamen", showing 

 the whole course of development of Muscineae and vascular cryptogams; and 

 the true relation between the asexually-produced spore, and the sexually- 

 produced embryo or sporophore, as well as the genetic relation of Crypto- 

 gams and Phanerogams. 



After these men came Prof. W. P. Schimper, also a German, who was, in 

 his day, the greatest living authority on Music. His greatest work, "Bry- 

 ologia Europaea", is a standard work of great value, adding very much to the 

 knowledge of bryology. 



Mueller, Hampe and Lindberg were all well-known bryologists and also 

 Germans. 



Of the English bryologists, the most prominent are: Wilson, now dead. 

 Mitten and Doctor Braithwaite, who are still living and working. Doctor 

 Braithwaite has just published a valuable book called "Handbook of English 

 Mosses", which is very clear, concise, and accurate. 



Renauld and Cardot are two French bryologists still working, who have 

 identified and named most of the Kansas mosses thus far reported. 



The first work on mosses in America was done by Doctor Muhlenberg, a 

 Lutheran minister of Lancaster, Penn., who published a catalogue of over 

 170 species; principally named by Hedwig and Beauvois. 



Later came Sullivant, who published his first edition of 205 species of 

 mosses, and later, in the year 1856, the second edition, containing 410 species. 



James and Lesquereux began their "Manual of North American Mossejs"; 

 but before it was completed James died (1882), so that Lesquereux finished it 

 in 1884, with some aid from Watson, Renauld, and others. This manual de- 

 scribes 128 genera, and nearly 900 species; but only the northern and eastern 

 states were thoroughly represented, as but little collecting had as yet been 

 done beyond the Mississippi river, or in the gulf states. 



There are a number of active bryologists in the United States now, though 

 most of them are comparatively young. Of these older ones, Macoun, Eugene 

 Rau and D. C. Eaton are best known, while of the younger ones, Mrs. E. G. 

 Britton and C. R. Barnes are most prominent. Mrs. Britton is now writing 

 a "Handbook of Mosses of Northeast America", which will be a very valuable 

 addition to American bryology. This will be published soon, we hope. 



Next in importance comes C. R. Barnes's "Artificial Key to North Amer- 

 ioon Mosses", published in 1890. This is a very great help in identifying 

 mosses, in connection with Lesquereux and James's Manual, making the 

 latter twice as clear, and hence more valuable. 



Recent additions to North American mosses have increased the number to 

 something over 1,000 species; and still but little territory has been studied. 



Kansas, like most of the western states, has had but little work done on 

 her mo&fces. In 1884, the first list of Kansas mosses was published in the 

 "Washburn College Bulletin", edited by Prof. F. W. Cragin. The collecting 

 was done by Professor Cragin's students chiefly, while the specimens were 

 sent to Eugene Rau for determination. 



This list contained but 12 species, all from the immediate vicinity of To- 

 peka. A'lditional species were reported from time to time, and the lists 

 publisheJ in the "Washburn College Laboratory Bulletin", giving new locali- 

 ties for mosses previously reported, until the fourth and last list was published 

 in 1886, numbering 53 species in all. These last lists included collections 

 from various counties over the state, many specimens being collected in
