82 SUMMARY OF CURRENT RESEARCHES RELATING TO 



melting snow at 8700 feet on Ben Muich Dhui, and was associated with 

 M. condensata, M. Stahleri^ Gymnomitrium varians, etc. A description 

 of the structural peculiarities of the plant is given. It is mainly a 

 Scandinavian species, but reaches the Alps of central Europe. 



Aplozia pusilla.* — C. Jensen describes and hgrn-esAploziapusilla, a 

 new species found associated with Dicranella secunda, Nardia h?jalina, 

 N. f/eoscyphos, Martin ellia rosacea, Rkcardia ping ids, etc. in Denmark, 

 Sweden, and Finland. It is a species which forms a sort of transition 

 between Aplozia and Nardia by having its involucral leaves connate to 

 the perianths. It is easily distingished from N. hyalina and N. paroica 

 by the cell-structure of its perianth. 



Exotic Acrocarpous Mosses. f — G. Roth publishes a supplement to 

 his Ausser-europJiischcn Laubmooseof 1910-11, adding descriptions and 

 figures of species belonging to the following genera — Andreaea (8 species), 

 Neuroloma (1), Arrhidinm (1), Briichia (1), Pleuridiwn (2), Aschisma 

 (1), Trachycarpidiuin (1), Acaulon (1), Lorentziella (1), Epliemerum (1), 

 Nanomitrium (1), Trematodon (3) ; also some critical notes on Brtichia. 



Italian Jubulacese.J— C Massalongo continues his monographs of 

 the hepatics of tlie Italian flora by publishing an account of the Jubu- 

 lacese, giving descriptions of the genera and species, analytical tables, 

 figures, etc. 



Tasmanian Bryophyta.§— L. Rod way publishes the first part of a 

 descriptive work on the Bryophytes of Tasmania, to the flora of wliich 

 150 new species have been added by the persistent labour of W. A. 

 Weymouth, whose large herbarium has been submitted to Brotherus, 

 Venturi, AVarnstorf, and Stephani. Rodway's work is not a mere 

 compilation, but consists of original descriptions of the rich material at 

 his disposal, preceded by a general structural account of the mosses from 

 the systematic point of view. 



Philippine Sphagna. ||—0. Warnstorf gives a short account of the 

 sphagna of the Philippine Islands, and records six species with their 

 varieties and forms. One of the species is new — Sphagnum Rohinsonii — 

 and its characteristic structure is described and figured.
