324 SUMMARY OF CURRENT RESEARCHES RELATING TO 



by him on one day at two localities in the neighbourhood of the Milse- 

 burg in the Rhongebirge. This list is of the nature of an appendix to 

 the 222 mosses recorded by A. Geheeb in his paper ' Die Milseburg im 

 Rhongebirge und ihre Moosflora' (Festschrift ties RMncliibs, 1901). 



L. Loeske * publishes a handbook to the mosses and hepatics of the 

 Harz Mountains, adding many species to the list contained in E. Hampe's 

 Flora Hercynica (1873). The book consists of an introduction, keys 

 to the genera and species, critical and distributional remarks on the 

 species, and a bibliography. 



W. Monkemeyer f calls attention to the rich moss-flora of the Fick- 

 telgebirge, which though studied a century ago by H. C. Funck and 

 later by Laurer and by Molendo was far from exhaustively examined, 

 especially as regards the hepatics ; and he publishes a preliminary list 

 of 24 hepatics and 62 mosses, of which 7 and 14 respectively are new 

 to the district. 



The same author J gives a list of 127 mosses and 13 hepatics and 

 numerous varieties gathered in the Wesergebirge. 



F. Matouschek § describes a new variety of the widely distributed 

 Pylaisia polyantha with crispate leaves, analogous to the crisped form 

 of Leucodon sciuroides described by him last year. 



Austrian MuscineaB.|| — F. Matouschek has examined the collections 

 of Breidler and others, and drawn up a localised list of 161 mosses and 

 62 hepatics gathered in Moravia and Austrian Silesia. There are no 

 new species. 



Italian Mosses. If — A. Bottini publishes a list of the acrocarpous 

 mosses gathered in the Tuscan Archipelago by Beguinot, Sommier, and 

 Marcucci at various times in the past thirty years, and recently worked 

 up by himself. Some six varieties are new to science ; one species is 

 new to Italy and 40 are new to the Archipelago, while the mosses of 

 Pianosa and Montecristo are recorded for the first time. The pro- 

 montory of Monte Argentario is regarded as belonging to the archi- 

 pelago rather than to the mainland. 



North American Mosses.** — N. C. Kindberg insists upon the im- 

 portance of a close comparison of the moss-floras of Europe and North 

 America. Several examples are cited of species which, though regarded 

 as exclusively American, have turned out to be identical with European 

 species ; and again of species which are sterile or rare in Europe and in 

 America are found to be fertile or common respectively. And amid 

 some further critical remarks he introduces descriptions of three new 

 species of Brywn and one of Orthotrichum — all from North America. 



Mosses of Alaska.tf — J. Cardot and I. Theriot give the bryological 

 results of the Harriman Alaska Expedition — a list of 280 species, in-
