BRYOLOGICAL NOTES 

 V. Scapania nimbosa from Norway 



By a. LeRoy Andrews 



Of the remarkable "Atlantic species" of the northwestern 

 European coasts washed by the Gulf Stream, obviously relicts 

 of an older flora, two Scapanias stand out sharply from their con- 

 geners. The one of wider distribution, commonly known as 

 Scapania planifolia (Hook.) Dum., should according to Pearson 

 bear the earlier specific name S. ornithopodioides (Dill.) Pears, 

 It is known from various stations on the west coasts of the Brit- 

 ish Islands, from the Faroes and a few localities on the west 

 coast of Norway. According to M tiller* it is certainly identical 

 with species known from isolated stations in Hawaii and the 

 Himalayan region of India. f S. nimbosa Tayl. was hitherto 

 known only from relatively few places on the western coasts of 

 the British Islands. 



* Rabenhorst, Kryptogamenflora, VI, 521. 1915. The author's earlier (1905) 

 monograph of Scapania is not at present accessible to me. 



t This conclusion is also accepted by Stephani, Spceies Hepaticarum, I\\ i36f. 

 1910.
