326 SUMMARY OF CUKRENT RESEARCHES RELATING TO 



Mansfield, Vermont. It had been previously slathered in northern 

 Labrador by Macoun in 1896, and described by Kindberg. 



Swiss Mosses. — C. Trautmann* describes a few of the mosses 

 collected by him in the Bernese Oberland, of which the most interesting- 

 and imT^ovtiint'was Orthotrichum perforatum Limpricht. This w'as origin- 

 ally found growing plentifully in one locality in Tyrol, and also in Styria. 

 It is here recorded from four different situations in the Bernese Oberland, 

 all above 2000 m., where it is not at all plentiful. The author finds it a 

 very variable species, the only part of it which remains constant being 

 the calyptra. With 0. perforatum was growing 0. Sardaynanam Vent. ; 

 and other rare and interesting species are recorded. 



Ch. Meylanf last year searched the Jura mountains of Berne and 

 Soleure, and succeeded in adding four genera and twelve species to the 

 Jura flora. Six of these species are alpine. The erratic blocks of the 

 district have yielded some interesting species. The list contains 70 

 mosses and 26 hepatics. 



Mosses of the Erzg-ebirge.l — J. Roll gives a summary of the 

 results ol)tained by him from a study of the moss-flora of the Erzgebirge 

 during a period of thirty-two years. First he enumerates the stations 

 visited and the principal species gathered at each in the different years. 

 He then reviews briefly all the papers which he has himself published in 

 connection with this subject, and also the publications relating thereto 

 of SchiflFner, Bauer, and Monkemeyer. He defends himself against the 

 criticisms of Warnstorf, and maintains that the right principle of 

 working is to study the plants in the field rather than in the herbarium, 

 and to take into account the innumerable forms and connecting links 

 between the so-called types. He then supplies a list of the species 

 recorded for the Erzgebirge, with their localities ; and a similar list of 

 Sphagnacete, in great detail of varieties and forms. The moss-flora of 

 the Erzgebirge is less rich than that of the Fichtelgebirge or the Harz, 

 and the Saxon part of the range is less rich than the Bohemian 

 w^atershed. 



Mosses of the Austrian Protectorate.§ — J. Glowacke publishes the 

 second part of his bryological contributions from the protectorates of 

 Bosnia and Montenegro. He gives lists of the mosses collected in 23 

 additional localities, indicating the height above sea-level and the 

 geological nature of the soil where each collection was made. 



Bryophytes of Majorca. — W. E. Nicholson|l publishes lists of 78 

 species of mosses and 9 hepatics gathered by him in Majorca during a 

 short visit in June, 1905. The phanerogamic flora is remarkable as 

 containing three per cent, of endemic plants : but the moss-flora 

 presents no such peculiarity. Under the influence of the very dry 

 climate the species are few, even in the mountains, and tend to the 

 xerophytic type ; and there is apparently a total absence of the genera
