68 SUM.MARY OF CURRENT RESEARCHES RELATING TO 



the species out of Riccia ; it is allied to Ricciella crystalline/,. He gives 

 critical remarks on four rare species of Lophozia, on Pedinophyllum 

 interr upturn. Pedinophyllum, being more closely related to Mylia and 

 to Chiloscyphus than to Plagiochila, should be kept separate from the 

 latter genus. Finally Evans treats of Frullania inflata and of F. saxicola 

 Austin. The latter is a good species ; but how far it may beconspecific 

 with the European F. cleistostoma of Scbiffner and Wollny, he is not 

 prepared to say until he has examined specimens of the latter. 



North American Bryophyta.* — 0. E. Jennings gives a brief descrip- 

 tion of the great Pymatuning Swamp in north-west Pennsylvania, and 

 of its main plant-associations. He was surprised to find one small urea 

 covered with Polytrichum strictum Banks, a northern alpine never before 

 recorded from so far south nor from so low an elevation. 



A. Lorenz f publishes some brief notes of her collecting experiences 

 during a European trip, principally in Germany and Switzerland, and 

 compares the moss-floras of the localities visited with those of similar 

 spots in the United States. 



E. J. Hill $ gives an account of the collection of mosses made by 

 J. Roll in the United States and Canada in 1888-9, and of the late 

 C. R. Barnes's contribution to the determination of the species. 



W. W. Calkins § gives a list of fifty-one mosses collected in Cook 

 County, Illinois, and all found growing within a radius of ten to twenty- 

 two miles from Chicago.

Mexican Mosses. || — J. Cardot publishes his seventh article on 

 Mexican mosses, and gives descriptions of seventeen new species, a few 

 varieties and two new genera Barmsia and Morinia, both members of 

 the tribe Trichostomese. The former is named after the late C. R. Barnes 

 of Chicago ; and Morinia is named after Morin, author of a paper 

 on the histology of leaf -nerve of the mosses. The specimens upon which 

 the paper is based were collected by Pringle, by Barnes and Land, by 

 Purpus, and others. 



Moss-flora of Bolivia. 1" — T. Herzog publishes some further contri- 

 butions to the moss-flora of Bolivia, founded on two collections ; one 

 made by himself, and the other sent by 0. Buchtien to J. Kaulfuss. 

 Herzog's gathering contains twenty-one species, seven of which are new. 

 Buchtien's contains twenty-five species, four of which are new. In all, 

 some 700 species have been recorded for Bolivia. 



Bryophyta of the Philippine Islands.** — E. D. Merrill and M. L. 

 Merritt in their account of the flora of Mount Pulog, in the Philippine 

 island of Luzon, include a list of twenty-three hepaticas and thirty-four 

 mosses determined by F. Stephani and V. F. Brotherus respectively. A 

 description of the ascent is given, and the flora of the various zones is 

 discussed and compared with that of other regions.
