312 RECORDS OF THE BOTANICAL SURVEY OF INDIA. 
Brachythecium indico-populeum Dixon sp. nov. (Plate I). 
Habitu B. populeo persimile, Differt costa plerumque in acuminis 
basi evanida, foliis perichetialibus argute dentatis, seta ubique minute 
distincte muriculata. 
Hab. Kunkar Valley, Bahai Pass, N.-W. Front. Prov., 6500— 
13,000 ft., July-Aug., 1924 (1060), type. Ibidem (1067). Bindi Pass 
‘and Kishongunie Valley, Kashmir, 8,000—14,000 ft., Aug. 1924 (1137), 
forma robusta, latifolia. 
Of the B. populeum group this differs at once from that species as 
well as from B. glabratum Broth. and B. spurio-populeum Broth. in the 
seta finely muriculate in all its length, and in the sharply denticulate 
perichetial bracts. No. 1137 is of very different habit, with large broad 
leaves, but structurally agrees exactly both in vegetative and fruiting 
characters. 
Brachythecium obsoletinerve Dixon sp. nov. (Plate I.) 
Subgen. Velutinium § Julacea Broth. 
Densissime cespitosum ; pallide viride, intus fuscescens; parum 
nitidum ; caules intertexti, breves, dense pinnatim ramosi, ramis brevi- 
bus, circa 4 mm. longis, apice decurvatis. 
Folia caulina parva, 1-1-25 mm. longa, deltoideo-ovata, cito breviter 
anguste acuminata, plicata, marginibus planis, superne minute denti- 
culatis ; costa pertenuis, seepe obsoleta fere, ad medium folium raro at- 
tingens ; cellule superiores parve, angustissime ; basin versus paullo 
latiores, alares plures subquadrate, pellucide. 
Folia ramea angustiora, oblongo-lanceolata ; plerumque falcata, pro- 
funde plicata, sensim breviter acuminata, cetera caulinis similia.

Hab. Tragbol, Kashmir, 12,000 ft. Aug. 1919, coll. R. R. Stewart

13,000 ft., Aug. 1924, coll. Garrett & Lillie (1097), co-type. 
A very distinct species, allied to B. curvatulum Broth., which differs 
in the recurved margin, strongly denticulate above, the very long subula 
of the perichetial leaves, ete 
The nerve is exceedingly narrow and thin, sometimes almost invisible, 
and often lost in a fold of the leaf. 
The co-type differs somewhat in habit, having the leaves less falcate, 
and branches less curved at the tip, very julaceous with the densely
