578 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Bridge in June 1904, growing in large patches on blocks of millstone 

 grit. The plant is about the size of L. gracilis, but that species is con- 

 fined to limestone and bears no stipules. L. atlantica had been recorded 

 for Britain only once previously, namely, from Caithness, D. Lillie, 

 1001 ; but it now appears to have been found by AV. B. Waterfall in 

 Cumberland, so long ago as 1886, and in Clyde Isles by S. M. Macvicar 

 in 1906. It is also found in Norway and the Faroe Isles. (2) The 

 author also points out the characters which are most useful for 

 distinguishing L. badensis Schiffn. {Jimgermannia acuta a Lindenb. ; 

 J. luridula Wils.) from L. turhinata Steph., with which it has been much 

 confused. He appends its distribution — namely, Scandinavia, Scotland 

 (4 stations), England (4 stations in Yorkshire and 1 in Sussex). 



C. A. Cheetham * contributes brief notes on two Yorkshire mosses, 

 namely Leslcea catemdata and Orthothecium rufescens, which have been 

 omitted in recent lists. 



Muscineae of North Devon.f— C. E. Larter publishes lists of 181 

 species of mosses and 62 hepatics gathered by himself, C. A. Briggs, 

 •W. Mitten (in 1875), and others, in 'the botanical districts of Braunton 

 and Sherwill in North Devon. Among them is Lophocolea (data Mitt., 

 a new species collected at Lynmouth by W. Mitten in 1875 : it is 

 described and figured. Notes on the earliest British records of 

 Dumortiera irrigua are given, Taylor having discovered the plant in 

 Ireland in 1820, and Wilson in 1829, and Ralfs in North Devon at 

 Combemartin in 1842. Fissidens MUfenii Tindall was found near 

 Barnstaple by Mitten in July 1875, and has never been gathered again. 

 The author has been aided in his work by Mitten, Dixon, and Macvicar. 



Moss-flora of Hamburg.|— G, R. Pieper and R. Timm give some 

 new results arising from a study of the Hamburg flora. These consist 

 of records of 21 hepatics, 4 sphagna, 36 mosses, with some notes on the 

 localities. 



European Sphagna.§— C. Warnstorf gives a conspectus of the 

 sphagna collected by Max Fleischer in different regions of Europe, 

 namely, in Norway, Switzerland, and France. Critical notes are 

 appended to the following : S. crassicladum, S. rufescens, S. Pylaiei var. 

 sedoides, all of which were gathered in Brittany. 



Swiss Mosses.ll— H. N. Dixon publishes notes on the more interest- 

 mg mosses collected by him in the Bernese Oberland, in the neighbour- 

 hood of Adelboden and on the Gemmi Pass. In the Alps the best 

 hunting-grounds for mosses are in the sub-alpine woodland and near the 

 the suow-hne. The pastures and pinewoods of the intermediate zone are 

 less productive. The northern approach to the Gemmi Pass is almost 

 glacial in its surroundings and in its flora ; but there is a sudden 

 transition in the moss-flora as the sheltered southern Valaisian zigzags 

 of the pass are descended, high alpine species being abruptly replaced by 

 sub-alpine and even meridional types. At an altitude of 6500-7500 ft.
