210 SUMMARY OF CURRENT RESEARCHES RELATING TO 



latitudes, but has hitherto not been found below about 62° N. latitude 

 (in Scandinavia). It was growing at an altitude of about 1600 ft. 



J. B, Duncan has discovered Octodiceras julianum Brid., an aquatic 

 moss resembling in general appearance young plants of Fontinalis, 

 growing on submerged timbers, stones, and boulders in the river Severn, 

 at and near Bewdley in Worcestershire and Shropshire. The plant was 

 previously known throughout Europe, and from North Africa to North 

 America. It is suggested that it may have been introduced with foreign 

 timber. 



Kabenhorst's Cryptogamic Flora of Germany (Musci). — The 36th 

 part of this work, by Dr. K. G. Limpricht, completes the account of the 

 genus Hylocomium, and of the Hypnaceae. The remainder of this part 

 and the whole of Part 37 are occupied by additions and revisions of the 

 descriptions of the families, genera, and species in the preceding parts. 



Lists and New Species. — F. Stephani * gives a list of 187 species 

 of hepatics, including 55 new species, gathered in the rich forests, &c, 

 of West Patagonia and South Chile by P. Dusen, who describes in an 

 introduction to the paper his travels and the geographical distribution 

 of the more interesting species. 



The same authors f treat the hepatics of the Magellan' s-Straits 

 territory in similar fashion. 136 species are recorded, and of these ten 

 are new. 



V. F. Brotherus J has described 66 new species in a list of 192 

 mosses gathered in Brazil and Paraguay, by C. A. M. Lindman during 

 his Eegnell expedition. 



P. Dusen § also gives a list of 24 vascular plants and 38 mosses, 

 one of which is a new species, collected in the arctic island of Jan 

 Mayen during Nathorst's expedition to the east coast of Greenland 

 in 1899.

Remarks on (Edogonia with. Semicircular Foot-cell.|| — A. ScherfFel 

 here describes the germination of the zoospores of (Edogonium rufescens. 

 This may take place in one of two different ways, according to whether 

 they become fixed to some substratum or remain free in the water. In 

 the former case there arises directly through a circular opening an 

 (Edogonium filament ; while in the case of those spores which remain 

 free in the water, the cell-contents break up into swarm-spores, which 

 in their turn escape. The zoospores of 0. Virceburgense behave in the 

 same manner. The oospores of both species were observed by the author, 

 but no antheridia. The attraction possessed by the oogonia for the 

 Bwarm-spores is noticed, and this may be attributed, according to the 

 author, either to a chemotactic influence, or, which is less likely, to 

 the fact that the oogonia form a convenient surface attachment for the 

 swarm-spores. In the concluding paragraph is described an interesting 

 malformation in 0. Vircebergense.
