194 CLXXIII. GBAMINEJ:. (J. D. Hooker.) \_Andropogon. 



52. A. Hackelii, Hook. f. ; stem tall stout, leaves narrow finely 

 acuminate, panicle oblong, rachis strict, branches smooth crowded in many 

 superposed whorls short very unequal smooth spreading simple each 

 with a solitary spike, sessile spikelets i-| in. golden yellow, callus very 

 short beard fulvous brown, gl. I obtuse glabrous, II glabrous awned, awn 

 of IV f-1 in., pedicelled spikelets rather shorter than the sessile, gl. I 

 oblong acute quite glabrous 5-7-nerved not awned keel eciliate, II shortly 

 awned. Chrysopogon, Wall. Cat. n. 8783. Wight Herb. n. 1030 (in 

 Herb. Kew). 



TBAVANCORE, Wight. NILGHIEI HILLS ; Gondaloo Ghat, alt. 4500 ft., Lawson. 



Stem 4-5 ft., or more, as thick as a goose-quill below, leafy, quite smooth, 

 branching upward, branches erect. Leaves 2-3 ft., by i- in, coriaceous, smooth, 

 pale glaucous green, striate, margins sub-scaberulous ; sheath subterete, keeled, 

 smooth, glabrous; ligule a ridge of hairs. Panicle 46 in.; branches in 6-10 

 whorls, -| in. apart, the longest about 1 in. long, rather stiff, tips hardly oblique, 

 beard of spreading rufous hairs. Spikes solitary. Sessile spikelets yellow ; gl. I 

 4-uerved, polished ; II subcymbiform, tip 2-lobed, 3-nerved, margins ciliolate, keel 

 rounded and thickened, awn shorter than the gl. ; III linear-oblong, obtuse, hyaline, 

 ciliate, nerveless ; IV very narrow, 1-3-nerved, hyaline, base and column of awn brown. 

 Pedicelled spikelets pale green ; yellow or purplish, male, pedicels = -| nearly \ the 

 sessile spikelets truncate, margins densely villous with long rufous hairs, the upper 

 of which = half the spikelets, gl. I thin, nerves subequidistant, or 2-3-nate pairs 

 submarginal margins narrowly incurved ; II lanceolate, 3-nerved ciliate ; III 

 oblong, 2-nerved, ciliate ; IV narrowly lanceolate, 1-nerved ciliate. A very 

 handsome plant with a bright golden panicle. Wight's n. 1030 (which is not a 

 catalogue number) is referred by Hackel to A. Trinii var. increscens, with the 

 locality Courtallam, taken from Steudel. It differs from the n. 1030 in Herb. Kew in 

 the villous sheaths with tubercle- based hairs, the leaves hairy on both surfaces and 

 panicle branches 4-8, and is no doubt rightly referred to Trinii. 



53. A. velutinus, Hook. /. ; stem not tall compressed, leaves linear 

 broad flat acuminate puberulous on both surfaces, sheaths strongly com- 

 pressed keeled, panicle with flexuous rachis and short flexuous scaberulous 

 branches minutely bearded at the truncate tips, sessile spikelets pale, 

 callus very short rufous bearded, gl. I compressed keel ciliolate above the 

 middle, keel of II hirsute, awn of IV 1 in., pedicelled spikelets oblong 

 truncate strongly 7-nerved not awned keels ciliate dorsally glabrous 

 or hirsute, pedicels very short. Chrysopogon velutinus, Arnott in Herb. 

 Wight n. 2314. 



MYSOEE ; at Cuddapah, Wight. 



Stems 18 in. high, rather stout, soft, tufted, leafy from the base. Leaves 

 6-10 by - in., distichous, flaccid, 5-9-nerved, slender midrib beneath and 

 margins spinulosely ciliolate and with a few long hairs at the base ; lower sheaths 

 equitant, 5 in. broad, strongly compressed and keeled, keel spinulosely ciliate, upper 

 sheaths finely pubescent. Panicle (imperfect) 2 in., branches -1 in. Sessile 

 spikelets ^ in., pale yellow; gl. I with minutely ciliolate margins; II margins 

 eciliate, gls. Ill and IV in both sessile and pedicelled spikelets as in A. monticola. 

 I have seen only one specimen of this plant which differs widely in habit and foliage 

 from any form of A. monticola, in the broad flat flaccid pubescent leaves and 

 sheaths. It is a native of a botanically unexplored district. 



54. A. polyphyllus, Hack. mss. in Herb. Duihie; stem simple or 

 fastigiately branched quite glabrous, leaves many long narrow rigid 

 acuminate flat pale glaucous-green glabrous coriaceous, sheaths terete,
