the ground that its stem-structure is not of the type of the Ortho- 

 trichacefe, among which Amphklmm is usually placed. In Anisotheci- 

 oideae he employs the generic name Pseudephemeriun (Lindb.) for 

 Pleuridium axillare. In Dicranoideaj he creates the new genus 

 Gongronia for Cynodontium strumifenim, Kiseria for the falcatum group 

 of Dicraiiam, and ScytaUna for Dicranurn montanum and D. fiageJlare. 

 In treating of the species he gives his reasons for converting several of 

 them into varieties of other species ; and he describes some nine new 

 varieties. 



British Bryophyta.* — AV. Ingham publishes the twenty-first annual 

 report of the Moss Exchange Club, in which P. G. M. Rhodes states that 

 a larger number of critical and atypical specimens have been gathered by 

 the members during the past year. The critical notes published in the 

 report are accordingly the more valuable for this reason, and treat of 

 both mosses and hepatics. 



Rare Mosses from the Iberian Peninsula.f — A. Luisier publishes 

 a series of chapters on new and rare mosses gathered in Spain and 

 Portugal : — 1. Triquetretta is a genus hitherto found only in Australia, 

 South Africa and Patagonia ; but T. arapilensis, a new species with 

 remarkable papillte, described and figured by the author, extends the 

 distribution of the genus to S.W. Europe. 2. Bruchia voyesiaca Schw. 

 and Didymodoii Ehrenlergii Kindb. (Trichostomum Lorentz) are very 

 rare species from the Vosges and Sinai respectively, and have been 

 detected by the author in the Iberian peninsula. 3. The North American 

 genus and species Claopodium WJdppleanum (SuU.) Ren. and Card, is 

 represented in Portugal by Leslcea algarvka Schimp., a synonym, and in 

 Spain by a cavern-variety. 4. Desmatodon meridional is, a new species 

 from the south of Portugal, is described and figured. 5. Brachymemum 

 lusitaaicum, a new species described and figured by Hageu, adds to 

 Europe a- genus hitherto known only from tropical and sub-tropical 

 regions. 6. The author adds nine species to Casares Gil's recent list of 

 Iberian mosses. 



Japanese Bryophyta. J — S. Okamura publishes an illustrated con- 

 tribution to the bryological flora of Japan, including descriptions and 

 detailed figures of a new hepatic, and twenty new species and five 

 varieties of mosses. He also describes Meteoriella, a new genus founded 

 on Meteor ium solutum. He also gives some excellent figures of a few 

 previously known mosses ; for example, Schist ostey a osmundacea Mohr. 

 The plants enumerated come from Sachalin, Liuchu Islands, and Corea.
