districts, followed by a general synopsis of the mosses other than Sphag- 

 num. He sets forth his views on the nomenclature of the Sphagnacese 

 and on the proper classification of the innumerable forms and interme- 

 diates. He follows Schliephacke in dividing the species into six groups ; 

 and under these groups he details the species, varieties and forms, inter- 

 spersed with notes. 



Moss-flora of Bernina.* — T. Herzog contributes a chapter on moss- 

 formations to E. Rubel's monograph on the plant-geography of the 

 Bernina Alps. He discusses the different types of habitat and the mosses 

 found thereon. One remarkable fact is the entire absence of mosses on 

 the tree-trunks, which, however, are covered with lichens. He describes 

 some half a dozen new varieties or forms and a new species. 



Mosses of Tirol. — C. Trautmann publishes a contribution to the 

 moss-flora of Tirol, comprising a list of fifty six species gathered chiefly 

 in the region of the Ortler during the month of July in 1909 and 1910. 

 The most interesting species is Orthotrichum perforatum, of which he 

 found two forms markedly different in the degree of development of the 

 peristome. 



Hungarian Mosses.} — I. Gyorffy gives an enumeration of the Sphag- 

 naceae gathered by him in the Hohen-Tatra in 1910 and determined by 

 0. Warnstorf . The list includes eleven species and twenty-eight varieties 

 and forms, with their stations, altitudes, etc. 8. imbricatum is a new 

 record for Hungary. 



The same author § publishes notes on the localities where fruiting 

 specimens of Plagiobryum demissum and Amphidium lapponicum have 

 been found on the Hohen-Tatra. 



Moss-flora of Bulgaria. || — J. Podpera, in giving an account of the 

 cryptogamic flora of the Bulgarian Alps, discusses the distribution and 

 ecology of the Bryophytes, and gives an enumeration of all the species 

 found. Some G000 specimens were examined and yielded 258 species of 

 mosses and thirty-eight of hepatics, and numerous, varieties and forms, 

 interspersed with critical notes. The interest of this moss-flora is that it 

 forms a link between the alpine floras of Europe and Asia. 



Crimean Mosses. — A. A. SapehinU" gives a resume in German of the 

 first part of his Russian paper** on the ecological, geographical, and floristic 

 aspect of the mosses of the Crimean mountains. He discusses the influence 

 of the climatic and edaphic factors upon the occurrence and adaptability 

 of the mosses of the district. He holds that the principal function of 

 the hairs and papilla? of the mosses is to scatter the radiant energy of 

 the sun. He divides the species into xerophytes and hygrophytes, not 

 according to their structure, but according to the nature of their habit.
