580 SUMMARY OF CURRENT RESEARCHES RELATING TO 



The same author * records the discovery of Ccphalozia catenulata at 

 Cherbourg by A. Martin, the chief interest being that this hepatic, 

 which is very rare in France and had been found only in high mountain 

 forests in the Vosges, Jura, Pyrenees, and Auvergne, gains at Cherbourg 

 a connecting link with the distribution of the species in the British 

 Isles, where it occurs as far south as Tunbridge Wells. The author 

 draws up in tabular form the characters by which the species is dis- 

 tinguished from its two nearest allies, C. lunulsefolia and C. connivens. 



Mosses of Central Europe.f — W. Migula publishes part v. of his 

 Kryptogamen-Flora, a continuation of Thome's Flora von Deutschland, 

 Osterreich und der Schweiz. Each part contains thirty- two pages of 

 test and six plates of figures, in black and white and in colours. Key 

 to the species, &c. are provided, and the descriptions are sufficiently 

 short. The present part deals with the Grimmiaceae and Orthotrichaceae. 

 The work is in German and the instalments appear at intervals of about 

 one month. 



Bohemian Species of Bryum.J — J. Podpera writes on the geo- 

 graphical distribution and natural grouping of the species of the genus 

 Bryum which occur in Bohemia, adding critical remarks on the com- 

 parative distribution and development of the same groups throughout 

 the whole of Europe. The two great subgenera, Cladodium and Eu- 

 hryum, are mainly northern and southern in their distribution, attaining 

 their greatest variability in the Baltic and Mediterranean regions re- 

 spectively. Nearly four-fifths of the species of Cladodium (50 in 

 number) are exclusively northern, and nine are confined to the Alps. 

 Only five are found in Bohemia. On the other hand Eubryum is richly 

 represented in Bohemia. Nearly 72 of its species occur in Europe, 

 and half of these reach their highest development in the Mediterranean 

 region, while only twelve are purely northern. The author groups the 

 species in a synoptical table according to their natural affinities, adds 

 an artificial key, and deals with the individual species in detail, dis- 

 cussing their variability and distribution. 



Mosses of Madagascar. § — E. G. Paris publishes a third contribu- 

 tion to the moss-flora of Madagascar in collaboration with Renauld and 

 Cardot. The list contains 35 mosses, including 13 new species and 

 4 new varieties ; also five hepatics, three of which are new, determined 

 by Stephani. The plants were gathered in the following districts, — 

 Sakalave, Ankazobe, Betafo, and Moramanga. Critical notes are added. 



Australian Mosses. || — K. Midler's third and last posthumous con- 

 tribution to the biology of Australasia consists of 39 descriptions of 

 new species, gathered for the most part in Victoria and New Zealand, 

 and for the rest in Tasmania, New South Wales, Queensland, and New 

 Guinea, by various collectors. 



Bryological Notes.^I — E. S. Salmon continues his bryological notes, 

 his chief point being that the Burmese genus Thiemea cannot be main-
