2. Ischsemum rugosum, Salisb. Ic. Sth-jj. Ear. (1701) p, 1, t. 1. 

 Anruuil ; stems 1-2 ft. long, erect or ascending, slightly thickened 

 beneath the intiorescence, leafy, compressed ; nodes glabrous or bearded. 

 Leaves 4-6 by ^-k in., liuear-lanceolate, acuminate, flat, glabrous or 

 sparsely hairy, the margins scabrid, the uppermost leaves often reduced 

 to spathiforra lanceolate sheaths which partially enclose the racemes ; 

 sheaths compressed, loose, glabrous, the mouth auricled, the auricles 

 membranous, confluent with the truncate ligules. Eacemes usually 2, 

 erect, pale yellow, glabrous, 1-3 in. long, fragile ; rhachis trigonous, 

 ciliate on the dorsal angle. Spikelets reaching | in. long or more, linear- 

 oblong, the sessile and pedicellate closely pressed together ; pedicel of 

 the latter very short and thick, clavate, angular, confluent with the 

 bristly thick callus of the sessile spikelet. /Sessile spilcelets : lower iuvol.- 

 glume cartilaginous for | of its length from the base, the cartilaginous 

 portion pale yellow, shining, concave, crossed by 3-6 deep smooth ridges, 

 the upper third flattened, thinner, membranous, obtuse, with green veins, 

 the margins narrowly incurved, the outer margin winged ; upper invol.- 

 glume oblong-lanceolate, acuminate, keeled, the keel with a narrow 

 ciliolate wing below the tip; lower floral glume ovate-lanceolate, acumi- 

 nate, hyaline, male or empty, paleate, the palea hyaline, nai-row ; upper 

 floral glume ^ in. long, deeply cleft into 2 acute lanceolate lobes ; palea 

 linear-lanceolate ; awn reaching | in. long or more. Pedicellate spil-elets 

 variable, rather shorter than the sessile; lower invol.-glume like that of 

 the sessile or with fewer or sometimes more or less obscure transverse 

 ridges, the upper half of the glume broader and more oblique; upper 

 invol.-glume not keeled, otherwise as in the sessile spikelet; lower floral 

 glume as in the sessile ; upper floral glume oblong, obtuse, not awned.

 3-4 ft. long, solid, suiooth, stout, leafy. Leaves 6-10 by |-| in., linear, 

 flnely acuujinate, sparsely hairy, base rounded, cordate ; sheaths 4-6 in. 

 long, smooth, glabrous or sparsely hairy above, the mouth villous. 

 Eacemes 1-2, axillary and terminal, 3-5 in. long, densely villous with 

 soft white hairs. Spikelets reaching I in. long; callus of sessile spikelets 

 ^ery short and broad. Sessile spikelets : lower invol.-glume thinly coria- 

 ceous, broadly ovate, obtuse, dorsally villous all over, many-nerved ; 

 upper invol.-glume chartaceous, obtuse, silky, keeled, the keel with a 

 narrow ciliolate wing from the middle upwards ; lovver floral glume ovate, 

 obtuse, hyaline, 3-nerved, ciliolate, paleate, the palea as long as the 

 glume, narrow, obtuse ; upper floral glume shorter than the lower one, 

 cleft to the middle into 2 lanceolate acuminate ciliolate lobes ; palea 

 small, narrow ; awn nearly | in. long, the lower half dark brown, the 

 upper half yellowish-white. Pedicellate spikelets rather smaller than the 

 sessile, with similar glumes but awnless. Woodr. in Journ, Bomb. Nat.
