only from the Carpathian Mountains of Roumania. It is a remarkable 

 thalloid hepatic allied to Freissia qnadrata. 



South American Bryophyta.* — E. Irmscher gives an account of 

 the Bryophyta collected in Columbia by E. Mayor, namely, fifty-two 

 mosses, two sphagna and nineteen hepatics, among which were nine 

 new mosses, described by Irmscher and Brotherus. The sphagna and 

 hepatics were submitted to Warnstorf and Stephani respectively. 



African Mosses.f — H. N. Dixon publishes a list of thirty-one 

 African mosses, partly from the herbarium of the late W. Mitten, 

 partly from H. A. Wager and other collectors. Most of the specimens 

 were gathered in the Transvaal, others in Cape Colony, tropical East 

 Africa, Mauritius, Angola, Congo. Lindhtrgia is a genus founded on 

 a North American species by Kindberg ; Brotherus added a few species 

 from Asia, Abyssinia, United States ; Dixon now adds two more from 

 South Africa, which much resemble Pseudoleskea and Haplocladimn in 

 habit, but distinguished by the erect symmetrical capsule and by the 

 peristome characteristic of Lindhergia — the absence of processes on the 

 inner peristome, the densely papillose outer teeth, and the large spores. 

 In all, the author describes and figures ten new species and intercalates 

 many critical notes. 



Mosses of Lord Howe Island. J — V. F. Brotherus and W. W. Watts 

 give a hst of the mosses collected by Watts on Norfolk Island in 1911, 

 mostly on the twin mountains, Lidgbird and Gower, and in the deep 

 Erskine Valley between them, that is, at the south end of the island. 

 More than ninety species were collected, and twenty-two of these and 

 a few varieties are described, as being new to science. In an appendix 

 the works of previous authors on the bryology of the island are cited, 

 and hsts of their new species are given. 



Mosses of New Guinea.§ — M. Fleischer reports on the mosses 

 collected by the Dutch scientific expedition to New Guinea, namely, 

 by A. C. de Kock in 1911 and by E. F. Janowsky in 1912. He 

 describes and figures eight new species, one of which {Br other ohr yum 

 Dekockii) is the type of a new genus. A remarkable fact is the wide 

 distribution of Schlollieimia in the central mountains of New Guinea ; 

 for this genus has its centre in the Andes of South America ; and 

 Fleischer concludes that there a great land-mass must have existed 

 between these two regions. An interesting discovery is that the dwarf 

 male plants of Schlotheimia Koningshmieri germinate in the old fruit- 

 capsules and develop there to full maturity. A number of critical 

 remarks add to the value of the systematic part of the paper.
