concave between the keels, which are neither Avinged nor margined 

 {i. e., of course, omitting the ordinary inflexed margins of the glume 

 common to the genus) or sometimes narrowly margined, scabrid or 

 ciliolate, nerves 2-4 or between the keels. Joints of rhachis and 

 pedicels subclavate with toothed tips. Ped. spkts. equal or rather 

 longer than the sessile, narrowly lanceolate, purplish, gl. i 7-9-nerved. 



Patna, Wall. (No. 8793 c) ! Fl. April. 



One of the Oil-grasses. See Stapf in Ken- Bulletin, 1906. Patna is outside its 

 normal distribution, but it was probably collected near the Ganges. 



2. C. Martini, Stapf. Syn. Andropogon Schoenanthus, F.B.I; Sail 

 tati, K. ; Nanha-dudhi-ghas, S. ; Rusa-oil grass. 

 A tall SAveet-scented grass 5-8 ft. high Avith glabrous straAv-coloured 

 leafy-stems and flat usually broad leaves with a rounded or sub- 

 cordate base, more or less glaucous beneath, those below the inflores- 

 cence rarely under 9" long b}^ -4" wide at the base but often 1" wide 

 beloAv, tapering from a little aboA^e the base or from the middle to a 

 fine tip, glabrous except for the scabrid margins, margins sometimes 

 smooth near the base. Geminate spikes •5--75" long oblique or 

 divaricate or less often deflexed. Peduncle about half the length of 

 the •75—1" long spatheole, several spatheoles and their peduncles from 

 a spathe of a loAA-er order, these arranged in long usually narrowly 

 oblong panicles not more than 1-5-2" Avide, but sometimes panicle 

 Avith many branches and broader. Joints and pedicels slenderly 

 clavate (exc. the much thickened lowest) about |- sessile spkts., tips 

 Avith lanceolate tooth or 3-t'oothed, margins long-villose. Sess. spkt. 

 •15--2" long, gl. i (above the loAACst spkt.) AA'ith lanceolate centre 

 becoming oblanceolate or oblong from the keels being membranously 

 winged above the middle, back with vertical median depression beloAv 

 middle corresponding to a ridge on the inside : ii cymbiform AA'ith the 

 dorsal keel AAinged aboA^e, minutely ciliate below. 



Chieflj^ on rocky hills with sparse forest. Mongiiyr, Mokim ! Gaj'a, common 

 on the ghats! Santal Parg. and Chota Nagpur, all districts, common, ascending 

 to the top of Parasnath, chiefly in the A'alleys and on the northern or shady sides 

 ■of the hills, locally abundant! Angul ! Sambalpur ! An undoubted perennial 

 {Hooker says "annual ?") forming buds in the autumn from a thick nodose root- 

 stock. Fl., Fr. Oct.-Dec. 



.'3. C. nardus L.* Syn. Andropogon nardus, L. 



A tall grass 5-7 ft. high copiously branched above and forming a 

 large decompound nodding panicle. Culms up to -4" diam. at the base, 

 solid, pale polished, AAdth black finely pubescent or glabrescent nodes. 

 Leaves narroAv Avith conspicuous Avhite midrib, loAAer several feet long 

 and about -6" wide, upper cauline rarely over -35" AAide, narrowed to 

 the base, apex filiform, glaucous beneath, glabrous except sometimes 

 at top of sheath, Avith scabrous margins ; ligule scarious -OS-'l" long 

 glabrous or ciliate. Panicle ultimate branches strict with 2-3 ped- 

 uncles and spathules from each spathe. Spathules -4 to about -1", 

 peduncles of spatheoles filiform •5--7" very shortly exserted from the 

 spathe ; spikes soon strongly reflexed on their common -4" long 

 peduncle, base SAVollen ciliate. Spikes •4--5" long unequally pedi- 



* This is not C. nnrdug according to Stapf who confines that species to the 

 ■cultivated awuless plant.
