464 SUMMAEY OF CURRENT RESEARCHES RELATING TO 



Wandel and Hovgaard ; 13 species are recorded, among them being one 

 novelty, Br achy thee ium Turqueti, and two new varieties. All the plants 

 collected were sterile. 



Muscineae of French Guiana.* — E. G. Paris publishes a list of 

 mosses and hepatics collected in this region in 1905, between Kourou 

 and Remire. The pleurocarpous mosses are, with one exception, species 

 common in the warm and temperate zones of Eastern inter-tropical 

 America ; but the interest of the collection lies in the six species of 

 Ckdymperes, all of which are new. Up to the present only five species 

 had been recorded for the three Guianas. Eight hepatics are recorded, 

 of which two are new. 



African Mosses.f — E. G-. Paris publishes a list of 25 mosses and 12 

 hepatics collected by Pobeguin in West Tropical Africa in the French 

 Niger Protectorate. Eight of the mosses and two hepatics are new, and 

 have been determined with the help of Brotherus and of Stephani 

 respectively. 



Australian Mosses.J — W. W. Watts and T. Whitelegge continue 

 their catalogue of the frondose mosses of Australia and Tasmania, col- 

 lated from available publications and herbaria records. The present 

 part, No. II., completes the acrocarpous species. It includes plants from 

 the Melbourne herbarium, and records 918 species, belonging to 44 

 genera. 



North American Mosses. §— E. G. Britton publishes a sixth chapter 

 of notes on nomenclature of mosses, basing her remarks upon Brotherus' 

 work in Parts 222 and 223 of Engler and Prantl's Pflanzenfamilien, and 

 calling attention to the points in which Brotherus has arrived at conclu- 

 sions similar to those recently arrived at by herself. 



A. J. Grout || replies to a criticism by E. G. Britton (in the same 

 journal in September 1904, p. 78) as to the determination as Playiothe- 

 cium Groutii Card, of a specimen referred to Raphidostegium recurvans 

 by other experts. The same author IF publishes notes on and descriptions 

 of sundry species, among them being Tetraplodon av.stralis, a new form 

 of Anaeamptodon splachnoides, Burnettia fabrofolia (sp.n.), B. subcapillata, 

 which has figured under Homalotkecivm, and five other genera. 



P. M. Towle ** gives the dates of maturing of the antheridia and 

 archegonia and spores in three species of Milium, together with other 

 facts in their life-history. 



Index of Mosses.ft— E. G. Paris publishes the final part of the 

 second edition of his alphabetical index of the mosses of the whole 

 world. In it are recognised 14,067 species and 397 genera. A map, 

 tables of distribution, and a concise summary, are appended. In the
