HOW figured. Until fruiting specimens are found there must be doubt 

 as to whether it is a true species, or a state of B. argenteum or some 

 other species growing in an abnormal habitat. A. Gepp. 



New Species of Aneura. — C. Massalongo {Bull. Soc. Bot. Ital., 

 1917, 80-82). A description of Aneura crinita, a new hepatic found 

 among mosses in a damp wood in the province of Perugia. In habit 

 and size it approaches A. pinguis, but differs in its calyptra, which is 

 beset with numerous long radicle-like hairs. A. Gr. 



Taxilejeunea ptero^onia and Certain Allied Species. — -A. W. Evans 

 {Bull Torrey Bot. Club, l'J21, 48, 107-36, 1 plate and figs.). A 

 detailed and critical description of four tropical American species of 

 Taxilejeunea, two of which are new to science. The genus belongs to 

 the section of Lejeunefe with bifid leaves, and contains large and con- 

 spicuous plants ; one of its most distinctive features is found in the 

 branches which bear the female inflorescences. These are short and 

 small-leaved, and on one or both sides produce short innovations termi- 

 nated by a female inflorescence. Thus a complicated branch-system of 

 cymose character is formed. A. G. 



Further Additions and Rectifications to the Moss-flora of 

 Switzerland. — J. Amann [Bull. Soc. Vaud. Sci. Nat., 1920, 53, 

 p. 81-12.5, figs.). The first series of "additions" was published in 

 Bull. Soc. llurithienne du Valais, 1918-19. The present series is 

 founded on collections made in Valais, on the Alps of 8aas and Zermatt 

 by the author, on the Great St. Bernard by Bender, in Ticino by 

 Jaggli, near Basle, etc. A careful study of the high Alps has yielded 

 interesting results, and shown that the moss-flora is even yet imperfectly 

 known. The stunted and sterile condition of the plants makes them 

 difficult to study ; but they are the more interesting as ecological 

 adaptations to severe conditions. The following species are described 

 as new to science : Barbuda pmnma, Syntrichia gelida, Bryum appendicu- 

 latum, B. britannise. Milium amblystegium. Nine other species are 

 added to the Swiss flora ; and twenty-eight new varieties and forms are 

 described. A critical study is made of the European species of Mnium, 

 especially those of the M. orthorltynclium group, from the point of view 

 of cellular tissue. The sporophyte of Ptychodium pallescens Amann is 

 described. A synoptic table for the determination of European species 

 of Hygroamblystegium is provided, as well as a revision of the Swiss 

 species. A. G. 



Mosses from the Kanara District. — H. N. Bixois {Journ. of Indian 

 Botany, 1921, 2, 174-8, 1 plate). A list of mosses collected by L. J. 

 Sedgwick in Western jMadras, partly in N. Kanara, partly in the drier 

 and more inland district of Dharwar. Ten species and a variety are 

 described as new to science, and figures of them are given. Critical 

 notes are appended to several other species. A. G. 



Bahama Mosses. — Elizabeth G. Britton {Bryologist, 1921, 24, 

 17-9, 1 pi). A list of thirty-three species of mouses collected in the
