Drier parts of India ; from the Paojab to Burma, and southward to CErLoir.— 

 DiSTRiB. Westwards to Sicily ; trop. Asia, Africa, and Australia. 



Very variable in habit and stature, rarely 12 in. high, tufted, annual or perennial ; 

 stem sometimes creeping and rooting, usually ascending from a leafy base, slender, 

 even filiform ; nodes sometimes densely bearded. Leaves 2-12 by ^^ -\ ip., acute or 

 acuminate, glabrous except at the ciliate base, rarely hairy, surfaces scabcrulous, 

 dull green ; sheath hardly compressed, glabrous or villous ; ligule short, membranoas, 

 truncate. Spihes pale or purplish ; joints and pedicels very slender = ^ the sessile 

 spikelet ; gl. I of sessile spikelet subacute, coriaceous; II 1-3-nerved; III linear, 

 oblong, obtuse, glabrous ; IV, awn i-f in., capillary, base slightly dilated ; palea 

 minute or 0. Pedicelled spikeleU like the sessile, male or neuter ; gl. I 7-13-nerved, 

 glabrous, pitted or not, keels ciliolate throughout their length ; II lanceolate, 6- 

 nerved, ciliate ; III linear-oblong, glabrous ; IV short or 0. — Lisboa describes the 

 spikelets as aromatic when crushed. Hackel has the following Indian varieties, all 

 of which, except longifolius, are united by various intermediates. 



a. genuinus ; gl. I thin not shining more or less villous below the middle, spikes 

 3-9. — Common. 



;3. Wightii ; sheaths villous, nodes long bearded, spikes about 15. — " Panvanasum," 

 Wight Cat. n. 1696. 



€. longifolius; tall, erect, stout from a woody stock, 2-4 ft. high, nodes densely 

 bearded, leaves 12-18 by J in. hairy, sheaths hirsute, lower spikes branched, spikelrts 

 quite glabrous, gl. I of lower spikelet coriaceous. A. Arnottianus, Nees in Wight 

 Oat. n. 2338.— Andropogon, Wall. Oat. n. 8803.— Ceylon ? Wight.— A very different 

 looking plant from the other forms of A. periusus. 



1). insculptus ; sheaths glabrous, gl. I of sessile spikelets 1-2-pitted truncate, 

 keels longer ciliate. A. insculptus, A. Rich. Tent. Fl. Ahyss. ii. 458. A. bifoveolatns 

 & subnnifoveolatus, Steud. Syn. O-ram. 380. — Not uncommon. 



19. Ai Foulkesii, Sook.f.; stem erect or ascending very slender, 

 nodes glabrous, leaves narrowly linear, sheatlis terete, spikes 3-6 1-1^ in. 

 long digitately fascicled long-stipitate slender purplish, joints and pedicels 

 shortly ciliate, sessile spikelets ^-J^ in. oblong-lanceolate dorsally de- 

 pressed in the middle line imperforate 7-nerved glabrous keels peotinately 

 ciliate. 



NiLOHiEl Hills, Wight ; Kaity, Foulkes ; Pykora, King. 



Perennial. Stem 12-18 in. Leaves 6-10 by ^-^ in., finely acuminate, glabrous 

 or hispid on both surfaces with spreading hairs, midrib very strong; sheath glabrous, 

 mouth and lignle villous with long hairs. Spikes 1-li in., special peduncles J-1 in., 

 very slender, axils bearded with long soft hairs ; joints and pedicels slender, flat with 

 thickened margins and diaphanous centre. Sessile spikelets -J— i in., tip 2-tootlied, 

 callus bearded ; gl. I dorsally flattened or convex, nerves obscure or distinct ; II 

 acuminate, S-nerved, keel scaberulous above, margins ciliate ; III shorter, lanceolate, 

 nerveless; IV awn 4-| in., capillary, palea 0. Pedicelled spikelet longer and 

 narrower than the sessile; gl. I strongly 9-nerved. — Resembles A. Ischcemum, 

 differing in the much shorter hairs of the joints and pedicels and glabrous spikelets. 



20. A. concanensis, Hook. f. ; slender, erect, leafy, leaves very 

 narrow sheaths terete, nodes glabrous, spikes 5-8 2-2|^ in. long loosely 

 fascicled long-stipitate slender flexuous pale, joints and pedicels slender 

 compressed not deeply sulcate sparsely shortly ciliate, spikelets | in. 

 ovate- or oblong-lanceolate narrowly truncate glabrous 7-nerved keels very 

 shortly ciliate. 



Bombay, Woodrow {Herb. Bomb. u. 28). 



Perennial. Stems many from a nodose stock, 28-24 in., firm, smooth, terete, 

 leafy. Leaves 8-10 by ^-\ in., finely acuminate, smooth on both surfaces; sheaths
