738 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Geneva Mosses.* — A. Gruinet gives an account of a moss-hunt on 

 the Plaine de Rocailles, near Geneva, in March 1910. He indicates the 

 species found respectively at the base and on the north side of the 

 erratic calcareous blocks so characteristic of the landscape, on the south 

 side of these blocks, on the surface of small "garides," amongst junipers, 

 on the ground, shaded or open, on stumps, etc. The presence of some 

 mountain species at an unusually low altitude is of interest. Special 

 notes on the habit of Rhodobryvm roseum, Fndlania Tamarisoi, and 

 Bryum argenteum var. lanatum, are added. 



Mosses of the Italian Islands.f — A. Bottini gives an account of 

 the moss-floras of the various Italian islands, namely, the southern 

 islands, Lampedusa, Linosa, and the Maltese group — Malta, Comino, 

 Gozo. Sicily and the Lipari group. The Neapolitan group — Capri, 

 Ischia, Procida, Nisida. Sardinia. The Tuscan Archipelago. The 

 Tremiti group in the Adriatic. The principal results are a total 

 number of 151 species recorded for Sicily ; 74 for Malta ; 68 for Sardinia ; 

 54 for Pantelleria. The most interesting species are Catymperes 

 Sommieri and Thamniwn cossyrense — novelties from Pantelleria, the 

 former being a moss of tropical affinities, and growing only beside a 

 volcanic steam outlet ; also Barbella strongylensis, a new member of a 

 genus previously known only from India and Ceylon. 



Polytrichacese of Western North America.^ — T. C. Frye publishes 

 an account of the Polytrichacea? of Western North America. He gives 

 a description of the family, followed by a synopsis of all its genera, and 

 a key to the seven genera found in North America. Similarly he 

 supplies a description of each of these genera and a key to its species. 

 In fine, he describes and figures each of the thirty-seven species 

 occurring in the area in question. 



Philippine Mosses.§ — V. F. Brotherus publishes a third contribu- 

 tion to the bryology of the Philippine Islands, comprising 144 mosses. 

 Among them are twenty-nine new species and a new genus, Psewlo- 

 racelopus, a remarkable member of the Polytrichaceas, occupying a 

 position between Racelopus and Pogonatum, and differing from the 

 latter by having its leaves destitute of all papilla? and its seta papillose ; 

 and from Racelopus by the structure of the leaves. 



Mosses of Western India.— H. N. Dixon || gives a description of 

 Brachymenium tvrgidum, a new species collected by L. J. Sedgwick in 

 the Western (ihats of South India. The internal lamella? of its peri- 

 stome teeth are very strikingly developed. It is allied to B. nepalense, 

 Jl. lanceolatum, and B. glaucum. 



L. J. Sedgwick H" gives an annotated list of thirty-five mosses from 

 Western India, collected in Mahablesbwar, Thana, Kanara, and other
