reduced, sometimes split in 2, upper very narrow, rigid, except at the 
hyaline margins, subacute to acuminate, 1—-3-nerved, nerves often more 
or less confluent into a broad rigid midrib. Valves oblong or lanceolate 
in profile, elliptic to broadly oblong when expanded, distinctly or 
obscurely keeled, at least in the upper part, truncate or minutely 
3-toothed, hyaline, glabrous, hairy along the nerves, finely 3-nerved ; 
callus bearded. Pales equalling the valves, faintly 2-nerved. 
Lodieules 2, minute, cuneate. Stamens 3. Ovary glabrous; styles 
slender, distinct ; stigmas laterally exserted. Grain oblong, sub- 
terete or slightly compressed from the sides; embryo about } the 
length of the grain ; hilum punctiform, basal. 
Dwarf densely tufted perennials, rarely annuals; blades setaceous; ligule 
hyaline, ciliate, short; spikes very slender, straight or gradually curved ; 
mS closely or loosely 2-ranked on the opposite or subopposite sides of the 
acnis. 
Species 6, in the dry regions of India, Algeria, and South Africa. 
The renewed examination of this genus has led me to the conclusion that its 
proper place is in Chloride near Microchloa, notwithstanding the superficial 
resemblance to Lepturus. It includes also the North African genus Kralikia, 
Coss. (Kralikiella, Coss. & Dur.; Arcangelina, O. Kuntze). 
or quite glabrous, scaberulous on the upper side, smoot below ; 
spike 1—% in. long, erect, straight, very slender, with the base 
enclosed in the uppermost sheath ; rhachis slender, quadrangular, 
sides striate; spikelets 1-11 lin. long, 1-flowered; rhachilla con- 
tinued as a short glabrous bristle ; lower glume of lateral spikelets 
suppressed, upper lanceolate-subulate, acute or acuminate, 13-1; lin. 
long, rigid, except at the hyaline margins, 3-nerved ; valve lanceolate 
in profile, 3-toothed, 1 lin. long, hyaline, 3-nerved, nerves pereurrent 
or very shortly excurrent ; anthers linear, 1 lin. long ; grain /inear- 
oblong, subterete.
