I- '.If. SUMMARY OF CURRENT RESEARCHES RELATING TO 



canals a few species are found. There is no trace of moss or lichen on 

 tree-stems, save on old and shaded willows near water. The wooded 

 region of the mountains, especially the pine forests, provide a number of 

 species. The author gives lists of the species found on rotten trunks, 

 rocks, river banks, etc. The alpine region is fairly rich in species. The 

 total moss-flora is about 220 species, and includes no species of Andrcsea 

 and Sphagnum. Hepatiea? are rare. The moss-flora is akin to that of 

 Europe, only two genera — Drummondia and Tndusiella — being extra- 

 European. The number of endemic species, apart from several forms of 

 Bryum, is about ten. 



Bryophyta of German Central Africa.* — F. Stephani gives an ac- 

 count of the hepatics collected by J. Mildbraed during the expedition of 

 Adolph Friederich von Mecklenburg in German Central Africa, princi- 

 pally between Victoria Nyauza and Ruwenzori. The number of species 

 is 56, and 48 of these are described and figured as new species. 



< '. VTarnstorf t has determined the Sphagnales of the same expedition, 

 five species and a variety. Three of the species are new. 



V. F. Brotherus $ treats of the mosses of the expedition. In 250 speci- 

 mens he found 137 species, 57 of which are new. Also 7 varieties and 

 the genus Leptodontiopsis are new. The plants were collected in the 

 following districts : — Bukoba-Bezirk, Ruanda, Rugega-Wald, Yulkan- 

 Gebiet, Ruwenzori, Beni, Gr. Kamerunberg. 



Bryophyta of Tropical "West Africa.§ — E. G. Paris publishes his 

 twelfth article on the Bryophytes of French tropical Africa, the present 

 consignment having been collected in Fouta Djallou, in French Guinea, 

 by Pobeguin ; near Bammako, by the Lieut-Governor of Haut- 

 Senegal-Niger ; in middle Casamance, by Etesse ; and at Assikasso, 

 on the Ivory Coast, by de Gondillac. In all, forty-six species and 

 varieties are enumerated, and fifteen of these are described as new. 

 Also ten hepatics, one of which is new, are recorded. 



Bryophyta of North America. — G. B. Kaiser || gives some field-notes 

 about sundry good collecting-grounds for Bryophytes and Lichens in the 

 Catskill Mountains. 



R. S. Williams IT publishes a description of Trichodon borealis, a new 

 moss collected by him near Dawson, Yukon Territory, in July 1899. It 

 appears to be allied to the Scandinavian T. oblongus. 



E. J.Winslow,** while collecting in a Sphagnum bog in Brownington, 

 Vermont, in July 1910, discovered the rare moss Paludella squarrosa, 

 which was previously unknown in New England, though recorded several 

 times for Canada. 



E. B. Chamberlaintt describes a peculiar form of Hylocomium pyre- 

 naicum from Quebec, in which the leaves, instead of being acuminate, 

 have a fringed 2-3 lobed apex. The meaning of the fringing processes 

 is not apparent.
