BBYOSEDGWICKIA, novum genus ENTODONTACEABUM, 



WITH FURTHER CONTRIBUTIONS TO THE BrYOLOGY OF InDIA. 



By H. N. Dixon, M.A., F.L.S. 

 (Plate 517.) 



In this article I continue the study of mosses received from 

 various parts of India {cf. Journ. Bot. 1911, p. 137). Since the 

 publication of the last article a further small collection made by 

 Mr. C. E. C. Fischer, in the Nilgiris, has come to hand, and 

 a considerable number of mosses collected by Mrs. F. Eoper, in the 

 spring of 1911, about Darjeeling have been placed in my hands for 

 study by Eev. C. H. Binstead. 



Before proceeding with these I should add that, in describing 

 the new genus Hyoiohilojpsis {op. cit. p. 137), reference should have 

 been made to the genus Beccaria C. MiilL, doubtfully and pro- 

 visionally reduced by him in the Genera Muscorum Frondosorum, 

 and treated by Brotherus as a section of Pottia (which includes 

 also Hyophila, Rymenostylium, &c., in C. Miiller's arrangement). 

 An examination of the specimens of Beccaria in the British 

 Museum shows that it closely resembles Hyophiloysis, but differs 

 in one or two important and essential characters ; the peristome 

 is wanting, not rudimentary as in HyopMlopsis, and the papillae 

 of the leaves are not on the face of the cells, but consist of coarse 

 tubercles on or near the cell divisions, giving a remarkably rugose 

 and striking appearance to the leaf. I may add that in a later 

 gathering of Hyophilopsis entosthodontacea received from Mr. 

 Sedgwick (No. 119), the papillae are very sparse and often wanting.
