quite smooth. Leaves $- in. bi'oad, flaccid, flat, margins smooth, nerves 3-5 on 

 each side of the slender midrib ; sheaths of lower short open, of the upper long 

 rather loose, quite glabrous ; ligule very short, membranous, glabrous. Panicle 2-4 

 in. ; rachis and branches stiff, angular, subscaberulous, rather stout, green. Spikes of 

 1-3 pairs of rather distant white spikelets ; joints = f the sessile spikelet, stout, shortly 

 villous truncate, pedicels= the spikelet, more slender. Sessile &pikelet terete ; callus 

 very short, stellately bearded with white hairs ; gl. I and II very coriaceous both with 

 strongly incurved sides, nerves very slender with many cross -nervules ; III oblong, 

 truncate, hyaline, 2-nerved, ciliate; IV short subrhomboidal, cleft to the middle into 

 triangular acute ciliate lobes; awn in the cleft f in., smooth, slender; palea linear- 

 oblong, ciliate, nerveless. Anthers long. Pedicelled spikelets very narrow, imperfect, 

 neuter, gl. I lanceolate, 9-nerved, bicuspidate ; II shorter, 5-nerved. A closely 

 allied species, with similarly densely silky white spikelets, has been collected by 

 Lunt in Southern Arabia, where it is stated to be cultivated. It is a stout plant 

 with much larger leaves and the habit of the ordinary Sorghum. The spikelets 

 are shorter and broader than in A. Stagfii, and are collected in a dense oblong 

 panicle. 



38. A. serratus, Thunl. Fl Jap. 41 ; tall, erect, leaves narrowly 

 linear, base narrow, lower branches of subsimple narrow elongate panicles 

 whorled, spikes solitary 2-8-jointed, joints pedicels and callus shortly 

 villous with rufous or purple hairs, sessile spikelets |- in. ovoid ellipsoid 

 or lanceolate, gl. I rufously hirsute towards the pale tip and sides, IY 

 shorty awned or awnless. Hack. Monogr. Androp. 520 ; Grah. Cat. Bomb.

Perennial. Stem 3-4 ft., subsimple, nodes bearded. Leaves 4-20 by -f in., 

 setaceously acuminate, glabrous or sparsely hairy on both surfaces, hairs often 

 tubercle-based, midrib broad ; sheaths terete below keeled upward, more or less 

 hairy ; mouth silkily villous ; ligule very short, truncate. Panicle 4-12 in., oblong, 

 rachis glabrous ; branches capillary, about equalling the spikes, glabrous or scaberulous, 

 whorls distant. Spikes i 1 in., red-brown ; joints and pedicels = the sessile 

 spikelets, margins shortly yillous. Sessile spi&elets, callus acute; gl. I coriaceous, 

 dark brown or nearly black, glabrous and polished on the middle dorsally, tips pale ; 

 II rather longer, lanceolate, acute, 1-nerved, hairy upwards ; III shorter, lanceolate, 

 acute ; IV small, oblong, entire or 2-lobed, awned or not. Lodicules ciliate. Pedicelled 

 spikelets narrower than the sessile, paler, hairy ; gl. I 7-nerved ; II 3-nerved ; III 

 and IV linear, ciliate. Roxburgh does not seem to have known this grass.
