 and Bolampatti Hills, 2500 ft. alt., 1911 (Nos. 25, 56), c. fr. ; all 

 leg. Fischer. On trees, Lonavla, Western Ghats, 1903, leg. G. A. 

 Gammie, comm. Sedgwick (No. 101), c. fr. The leaves in this 

 species vary much, from almost entire to closely and finely serru- 

 late, even in different leaves on the same stem. 



Bryosedgwickia, Card. & Dixon, gen. nov. Entodontacearum. 



Habitus, folia, theca, &c. Pylaisiae. Peristomium internum ab 

 externo liherum ; membrana basilaris alta, pergranulosa ; pro- 

 cessus filiformes, nodosi, papillosi, haud perforati, dentibus ex- 

 ternis subaequilongi. Perist. externum Pylaisiae. 



It may possibly be a question whether some of the genera of 

 this Order, allied to Pylaisia, and differing inter se but little in 

 vegetative characters, are not founded on somewhat minute differ- 

 ences of peristome ; but accepting such a classification as, e. g., 

 that of Brotherus (in Engler & Prantl, Pflanzenfamilien), the plant 

 on which we have founded this genus certainly stands clearly 

 apart, and to unite it with any of the existing genera could only 

 be consistently done by a total reconstitution of the Order, and by 

 " lumping " together a number of well recognized generic groups. 

 Platygyrmm, for example, and Platygyriella Card., a new Mexican 

 genus, scarcely differ from Pylaisia except in the absence of a 

 basal membrane, and Giraldiella C. M. in little but the estriate 

 outer teeth ; and the character of the endostome in our genus is 

 distinctly of more importance than such differences as these. 

 Pylaisia nana Mitt., from Japan has, as Mons. Cardot informs me, 

 a granulose basal membrane, but the processes are broad and of 

 the normal Pylaisia type. The new genus will therefore probably 

 be considered by most bryologists as a very well founded one. 

 We have named it after the collector, Mr. Sedgwick, from whom 

 I have received many interesting Indian mosses.
