186 CLXXIII. GRAMINEJS. (J. D. Hooker.) [Andropoyon. 



few or many in a whorl flexuous, spikes subsolitary, joints pedicels and 

 callus villous with long white or red brown hairs, sessile spikelets 3 in. 

 oblong-ovate, gl. I 5-7-nerved villous all over tip acute, II 2-fid, awn long 

 stout. Hack. Monogr. Androp. 524. Sorghum purpureo-sericeum, Asch.

Stem 3-4 ft., erect; stout or slender. Leaves 8-10 by -J in., linear, finely 

 acuminate, sparsely hairy, margins hardly scabrid ; sheath, ribbed, glabrous or 

 margin fimbriate, mouth villously silky ; ligule very short, ciliate. Panicle 4-10 

 in., erect; rachis glabrous ; branches ^-1 in., capillary. Spikes 1-1^ in., rarely of 

 3 joints, sometimes of one sessile and 2 pedicelled spikelets, joints about % the 

 sessile spikelet. Spikelets erect or spreading or pendulous, dorsally flattened ; gl. I 

 coriaceous, margins involute from base to apex, keels rounded, villi red-brown or 

 snow-white ; II as long as I, acuminate or aristulate, dorsally rounded, coriaceous ; 

 III hyaline, epaleate, 2-nerved, ciliate ; IV very fragile, 3-nerved, below the middle 

 ciliate with long hairs; awn 1-1^ in., column stout red-brown twisted glabrous; 

 palea minute, ciliate. Pedicelled spikelets usually shorter paler and narrower than 

 the sessile; gl. I thinner, 7-nerved, shortly silky ; II and III as in the sessile; IV 

 lanceolate, acuminate, 1-nerved, ciliate, male. The Indian differs from the African 

 plant in having rather smaller spikelets, in gls. I and II of the sessile not or less 

 scariose at the tip. The pubescence of the spikelet is more copious and pure white 

 in a Deccan specimen from Woodrow, and in a Pan jab ? one from Stewart. Hackel 

 has named Duthie' s specimens A. purpureo-sericeus var. variegatus. 



Subgen. VI. VETIVERIA, Hack. Spikes panicled, branches of panicle 

 many, whorled; joints 3 or more and pedicels linear filiform dorsally 

 convex not channelled, tip truncate. Sessile spikelets laterally or dorsally 

 compressed, awned or not; gl. I coriaceous, narrow, margins inflexed or 

 involute, keels muricate ; II awned or not ; III hyaline ; IV entire or 

 2-fid, awned. Lodicules glabrous. 



But distinguished from Chrysopogon by the absence of a beard of rigid hairs on 

 the tip of the branchlets, seen after the fall of the spike. A. venustus is removed to 

 Amphilophis. 



40. A. squarrosus, Linn. f. Suppl. 433; stem stout, leaves long 

 rigid, sheaths strongly compressed, panicle narrow, branches simple strict, 

 spikes many-jointed joints and pedicels glabrous, sessile spikelets linear- 

 oblong glabrous, gl. I coriaceous acute dorsally flat, margins broadly 

 inflexed muricate, IV linear-oblong mucronate or shortly awned. Vahl
