Andropogon.] CLXXIII. GRAMIXEJJ. (J. D. Hooker.) 191 



Stem several feet high, stout, terete, leafy, quite smooth. Leaves \\ ft. or more 

 by 4 a m > flat) rather thin, many- nerved, beneath and midrib quite smooth, base 

 rather contracted ; sheath terete, smooth, glabrous; ligule a ridge of minute hairs. 

 Panicle 6 by 2 in., peduncle stout as thick as a duck's quill ; rachis stout, terete ; 

 branches very unequal, longest 2-3 in., each with usually 23 spikes. Sessile 

 spikelets, callus -$ in. ; gl. I 4-nerved, polished ; II 2-lobed, awn as long as itself, 

 margins not ciliatej III oblong, obtuse, hyaline, 2-nerved; III the linear hyaline 

 3-nerved eciliate base of the awn. Pedicelled spikelets pale green, pedicels sparsely 

 villous on the margins and back with short rufous hairs, unequal, and shorter 

 than the sessile spikelet; gl. I narrowed into an awn often as long as itself, lateral 

 3 nerves on each side submarginal ; II and III lanceolate, acuminate, retrorsely 

 ciliate, II 3-nerved, III 2-nerved. The specimen in Herb. Wallich consists of a 

 portion of a stem a foot long, a panicle fully emerged from a leaf-sheath, with 

 suberect branches which will probably spread later on, and several leaves. Another 

 in Hamilton's Herbarium (now at Edinburgh) corresponds precisely. It is nearly 

 related to asper, but a very robust tall plant, the branches of the panicle are much 

 more numei*ous and longer, the leaves glabrous and not spinulosely margined, the 

 spikelets much larger, the callus shorter, and the margins of gl. II of the sessile 

 spikelet eciiiate. It may prove to be a form of A. verticillatus. 



Glumes I and II of pedicelled spikelets both, awned. 



48. A. Wigrhtianus, Steud. Syn. Gram. 395 ; leaves linear acute 

 glabrous or pubescent spinulosely serrulate, lower sheaths compressed, 

 rachis and branches of panicle minutely hairy, sessile spikelets % in., callus 

 long densely bearded all round, gl. I laterally compressed above, minutely 

 truncate glabrous below hispid above, II long-awned hispid above on the 

 keel and sides, awn of IV 2-2 in., pedicelled spikelets lanceolate pubescent 

 much longer than the sessile. A. aristulatus, Hochst. ex Steud. Syn. Gram.

Variable in habit ; stems short or tall, erect or ascending from a short stout 

 creeping stock. Leaves 3-10 in., rigid, from glabrous to pubescent on both surfaces 

 and with sometimes tubercle -based hairs; sheath glabrous ; ligule very short, villous. 

 Panicle 3-5 in., contracted, lower branches long, few in a whorl. Spikes solitary, 

 green or brownish. Sessile spikelets subcylindric ; callus long, hairs rusty ; gl. I 

 obscurely 4-nerved, tip 2-dentate ; II chartaceous, tip 2-lobed, awn as long as the 

 gl. or shorter ; III linear-oblong, 2-nerved, ciliate ; IV awn with a narrowly dilated 

 2-lobed base, column hispid. Pedicelled spikelets nearly ^ in. ; pedicel truncate, 

 margins shortly villous ; gl. I glabrous or pubescent, 7-nerved, awn longer than the 

 gl., keels ciliate; II lanceolate, 3-nerved, awn as long as the gl, or shorter; III 

 oblong, 2-nerved, ciliate; IV very narrow, ciliate, nerveless. I have seen no Ceylon 

 specimen of this species ; Thwaites' C.P. n. 3248 in Herb. Kew, is a starved specimen 

 of A. zeylanicus. Nor have I seen Burmese or Anam ones. 



49. A. distichopyllus, HooTc. f. ; stem stout fastigiately branched, 

 leaves distichous erecto-patent narrowly linear rigid smooth, sheaths 

 terete, panicle very long-peduncled narrow, branches very unequal erect 

 smooth with one terminal spike, sessile spikelets ^ in. callus elongate 

 shortly villous all round, gl. I 2-cuspidate quite glabrous, II glabrous, 

 awn of gl. IV 2| in., pedicelled spikelets longer than the sessile lanceolate, 

 gl. I glabrous 7-nerved keels ciliate at the tip only.
