and pedicels -05- -08" long, villous one or both sides and callus scantily 

 bearded. Sessile spikelets subimbricate, gl. i oblong, rarely elliptic- 

 oblong, obtuse, 5-nerved betAveen keels, tip neither winged not den- 

 ticulate, shoulders hispid and with long cilia and back more or less 

 hairy, rarely glabrous ; ii with ciliolate margins ; iii glabrous or 

 ciliolate ; iv awn -S-'S" long. Ped. spkt. about as long as sessile 

 rather narrower, gl. i 7-8- rarely 11 -nerved between the keels.

The spikes are sometimes compouud and the brandies have ciliate tubercles in 

 their axils otherwise their peduncles are glabrous. 



3. D. Clarkei, comb. nov. Syn. Andropogon Clarkei, Hack. 



A very distinct and pretty species, very slender and much branched, 

 12-18" high ; nodes mostly pubescent. Leaves 2-4" linear to almost 

 linear-lanceolate, up to -15— -2" broad in the middle, cuspidately 

 acuminate, ligule of hairs. Spikes solitary -7-1" long, on capillary 

 peduncles scarcely exserted from the spathiform leaf-sheaths or leaves 

 (the bases of which embrace them). Easily recognised from the 

 contrast of the very white villous joints and pedicels, white-tomentose 

 gl. i of the sessile spikelets, and dark brown glabrous pedicelled spike- 

 lets. Sessile spkts. distichoush^ secund, pedicelled distichous. 



Parasnath, at the top, Clarke ! Fl. Sept.-Oct. Annual. 



Joints and pedicels sulcate, two lowest pairs of spikelets neixter. Other sess. 

 spkts. '12" long, gl. i elliptic-oblong truncate 2 toothed, keels scaberulous, calkis 

 very short; ii white, narrowly cymbiform, margins ciliate; iii oblong hj'aline 

 ciliate ; iv, aAvn 'o-l" long. 



73. HETEROPOGON, Pers. 



Short or usually tall grasses with linear or sub-ensiform leaves and 

 solitary terminal many- jointed spikes. Spikelets 2-nate, sessile and 

 pedicelled, lowest 2-8 prs. closely imbricate subsimilar in shape and 

 colour and alike in sex, male or neuter, awnless, their joints hi-mly 

 cohering, the sessile and pedicelled spkts. of other pairs very different 

 and their joints disarticulating. Sess. spkts. subcylindric, callus long 

 and often pungent Avith a barb of hairs ; gl. i sub-cylindric or oblong ; 

 ii cymbiform or linear AA'ith a rounded keel in Avhich the aAvn of iv lies, 

 aw^nless ; iii hyaline ; iv reduced to the base (or base hardly any) of 

 a long aAA-n Avith a stout column. Pedicelled spkts. male or neuter, 

 very different from the heterogamous sessile, often similar to the 

 homogamous, more or less concealing the sessile ; gl. i usually many- 

 nerved ; iv hj^aline, aAvnless. Lodicules fleshy obeuneate-quadrate 

 with depressed glabrous top.

(Sambalpur) ; Dauria, Sinkola, Or. ; The Spear grass. 



A tufted and usually densely gregarious grass, 1-3 ft. high on poor 



soils, often 5 ft. in valleys and rich soils, often fastigiately branched. 



Leaves somcAvhat glaucous 4-12" by •1--2", acute or obtuse, scabrid 



above and on midrib beloAv, sometimes somcAvhat hairy, sheaths keeled 



and also sometimes hairy, ligule very small scarious truncate ciliolate.
