212 SUMMARY OF CURRENT RESEARCHES RELATING TO 



South American Species of Riccia.* — V. Schiffner treats of some 

 South American species of Riccia. 1. Riccia ochrospora Mont, et Nees, 

 collected in Chile by Bertero ; the original specimen in Herb. Liuden- 

 berg, being re-examined, proved to have a ripe sporogonium ; and thus 

 enabled a description of the spores to be given. '2. R. synspora Schiffn. 

 is a new species collected by Reineck and Czermak in Brazil, and 

 formerly referred to R. membranacea Lindenb. and Gott. by Schiffner, 

 but now carefully distinguished from that species and furnished with a 

 description. 3. R. echinatispora Schiffn. is a new species, the descrip- 

 tion of which will appear in the forthcoming report on the Brazilian 

 Expedition ; but in the meantime some notes on the development and 

 structure of the sporogonium and spore are given. 



Muscinea? of French Guinea.! — E. G. Paris publishes a bryological 

 flora of French Guinea, comprising 183 mosses and 33 hepatics. Six 

 years ago not a moss nor an hepatic was known from that district, but 

 thanks to the exertions of H. Pobeguin and two other French officers, 

 the present total has been reached. Of the mosses, 72 p.c. are endemic ; 

 of the hepatics, 13 p.c. Five new species of mosses are described ; and 

 descriptions of most of the others published in recent volumes of the 

 Revue Bryologique are reprinted in the present paper. 



Congo Mosses.J — J- Cardot publishes a second article on the 

 mosses of the Belgian Congo and the Casamance, in which he gives 

 preliminary diagnoses of ten new species collected by Hens, Vanderyst, 

 and Laurent on the Congo, and by Mathieu on the Casamance. He 

 describes three new genera : Fissidentella (Fissidentaceae), Nanomitriopsis 

 (Funariaceaj), Bry omnium (Bryacea?). 



Moss-flora of Java.§ — M. Fleischer publishes the third portion of 

 his monograph on the Musci der Flora von Buitenzorg, and treats of the 

 remaining seventeen families of the Isobryinse, and of the four families 

 of the Hookerinfe. He describes all the genera and species known to 

 occur in Java, adding numerous notes on families, genera, and species 

 which are found outside the limits of the island. Having submitted 

 the group of mosses to a rigorous examination, he has come to some 

 conclusions which are at variance with those expressed by Brotherus in 

 Engler's Pflanzenfamilien, and has been compelled to institute some new 

 genera and rearrangements. 



Hepaticse of the Philippine Islands. || — F. Stephani describes three 

 new liverworts — Anthoceros Mmeri, Playiochila Elmeri, Trichocolea 

 Elmeri — collected by A. D. Elmer, in Luzon, one of the Philippine 

 Islands. 



Two New Genera from Japan. IT — S. Okamura publishes an illustrated 

 account of two new Japanese genera of mosses, recently described by
