524 SUMMARY OF CURRENT RESEARCHES RELATING TO 



German Muscinese.* — K. Osterwald reports to the commission on 

 the German Flora upon the literature published in 1899-1901 upon 

 mosses and hepatics — 135 papers ; and gives alphabetical lists of the 

 new species, varieties, &c, and the new geographical records embodied in 

 the literature quoted. 



0. Jaap f in enumerating the cellular cryptogams of Rom Island, 

 North Friesland, quotes 113 mosses and 35 hepatics, with one new 

 species Bryum romoense. 



Italian Mosses. J — A. Bottini publishes a list of the pleurocarpous 

 mosses of the Tuscan Archipelago. These are 38 in number ; 8 of the 

 varieties are new to Italy and 4 are described for the first time. 



North American Mosses. § — A. J. Grout describes Polytrichum 

 Smithied,, a new American species resembling P. gracih and P. Ohioense ; 

 also a new form of P. commune. 



E. G. Britton || clears up the synonymy of Hypnum (Stereodon) 

 revohitum, a subarctic and alpine moss of the old and new world. 



J. W. Bailey ^ gives an interesting list of mosses which are commonly 

 found on Acer macrophylla, a large tree plentiful in the Western States. 

 Each of the 17 species mentioned always selects some particular part of 

 the tree, e.g. root, stem or branch, which suits it best. 



J. M. Holzinger ** shows that certain mosses gathered in Southern 

 France and named Seligeria tristiclia are referable to S. tristichoides 

 Kindb., a plant hitherto known only from Norway and North America. 

 Its European distribution is likely to be extended further. 



R. S. Williams ft nas made the interesting discovery that (Edipodium 

 Griffithianum, a British moss which is known also from Scandinavia and 

 Greenland, occurs in the Alaskan collections of the Harriman Expedition. 



J. Cardot and I. Theriot %% described 45 new species and varieties as 

 collected by the Harriman Expedition in Alaska ; 18 of the descriptions, 

 with critical notes, are reproduced in the Bryologist. 



Moss Flora of Australia. §§— W. W. Watts and T. Whitelegge, 

 having compiled a catalogue of the mosses of Australia and Tasmania, 

 publish the first part of it — 534 species of Sphagnacese and Haplo- 

 lepideous Acrocarpi. All available sources, such as published lists and 

 herbarium records, have been employed ; but great difficulty was ex- 

 perienced in dealing with the diverse principles of determination adopted 

 by such authorities as Wilson and Mitten on the one hand and C. Mueller 

 and Brotherus on the other. The question of synonymy was found in 

 several cases to be a matter of great uncertainty.
