Lophosin Baiieriana Schiffn., Lophocolea alata Mitt., Scapania ohliqua 

 Schiffn., Madotheca riviilavis Nees. He agrees with Schiffn. and 

 Arn eil in regarding Lophosin Baueriana as a valid species, and he 

 indicates the characters which are most useful for distinguishing it 

 from L. lycopodioides and L. Floerkei; and he Sketches out the distri- 

 bution of these three species in Britain. As to Lophocolea alata, 

 a new species published after Mitten's death by C. E. Larter in 

 Trans. Devon. Ass. Adv. Sei. 1906. p. 285, and founded on a Single 

 small specimen, Macvicar has examined several additional speci- 

 mens from the original locality in North Devon and elsewhere, 

 and finds that they vary so much in the specific characters emphasised 

 by Mitten, that he prefers to regard the plant as a subspecies of 

 L. ciispidata, which is not so common in England but more com- 

 mon in Scotland. He also records the occnrrence of Scapanm obliqua 

 in Britain, shows how it is distinguished from 5". undtdata und 5". 

 uliginosa and gives its British distribution. Finally he gives the 

 main characters and British distribution of Madotheca rivularis var. 

 siniplicior and var. faeroensis. A. Gepp. 



Nicholson, W. E., Cephalosiella patida (Steph.) Schiffn. in Bri- 

 tain. (Journal of Botany. XIV. July, 1907. p. 279, 280.) 



The author found in Crete, in the spring of 1906, a hepatic 

 identified for him as C. Baumgartneri by Schiffner, who has sub- 

 sequently shown it to be synonymous with C. patula Steph. Nicholson 

 has gathered the same species on chalk blocks near his own home 

 at Lewes in England. He contracts the plant with its close ally 

 C. integevrima Warnst., recently added to the British flora, showing 

 the differences of habit and habitat. A. Gepp.
