470 SUMMARY OF CURRENT RESEARCHES RELATING TO 



mosses and 18 hepatics made by R. Pampanini in the heart of the 

 dolomitic Alps of Cadore. He gives a list of the localities visited by 

 Pampanini, some notes upon the previous bryological literature concern- 

 ing this region, and adds some notes upon distribution. Three species 

 and 11 varieties are new to the Italian moss-flora ; 13 mosses and 

 6 hepatics are new for the province of Belluno ; and 39 species or varieties 

 are new for the province of Veneto. Specially notable are the very rare 

 species Grimmia Holleri and Bryum bimoideum. 



North American Mosses.* — A. J. Grout publishes the fourth part 

 of his " Mosses with Hand-lens and Microscope," a non-technical hand- 

 book of the more common mosses of the north-eastern United States. 

 It is freely illustrated from standard works, provides keys to the 

 genera and species, and emphasized descriptions with helpful annota- 

 tions. The purpose of the book is to enable moss-students to identify 

 all the less rare species with as little microscope work as possible. 



Hepaticae of Puerto Rico.f — A. W. Evans publishes his ninth con- 

 tribution to the study of the hepatic^ of Puerto Rico, giving an account 

 of the following genera : — Brachiolejeunea, Ptychocoleus, Archilejeunea, 

 Leucolejeunea, and Anoplolejeunea. 1. Two species of Brachiolejeunea 

 were already known from the West Indies ; to these is now added a 

 new species, B. insular is. 2. Ptychocoleus Trev. is here used to replace 

 Acrolejeunea as defined by Spruce and by Schiffner : P. polycarpus 

 occurs in Puerto Rico and is re-described by Evans. 3. Archilejeunea 

 is represented by A. viridisima in Puerto Rico ; a careful description of 

 this species is supplied. 4. The widely distributed Leucolejeunea xantho- 

 carpa occurs in Puerto Rico, and is re-described. 5. Anoplolejeunea of 

 Schiffner was monotypic. Evans finds the type to be indistinguishable 

 from Lejeunea conferta Meissn., and unites the two, giving a detailed 

 description of the species. Many critical annotations are included in 

 the paper. 



Mosses of the Canaries.! — H. N. Dixon gives an account of a small 

 collection of mosses made by Miss Wells in the Canary Islands. They are 

 twenty-two in number ; four of them are additions to the moss-flora of 

 the Canaries, and five to the moss-flora of the Atlantic Islands as a 

 whole. Brachythecium purum var. canariense is a curious novelty from 

 Palma. 



Bryophytes of French Guinea.§ — E. G. Paris reports upon a further 

 collection of mosses collected by Pobeguin in Fouta-Djallon, in tropical 

 French West Africa, including 20 mosses, six of which are new, and 

 3 hepatics, one of which is new. In a brief summary the author 

 points out that before 1902 not a Bryophyte was known from French 

 Guinea, but that owing to the efforts of three French collectors — 

 Normand, Maclaud, and especially Pobeguin — in six years 176 mosses
