fted, leafy at the base and occasionally with creeping stems rooting at the lower nodes varying in length from 10 to 21 inches. The _leaf-sheaths_ are glabrous, compressed, upper sheaths somewhat inflated; mouth of the sheath is bearded with long hairs in the leaves of young branches and quite glabrous when old and in flower-bearing branches, margins are thin and membranous. The ligule is a thin narrow membranous ridge. The _leaf-blades_ are rather narrow, linear, flat, acute, glabrous when old, and with scattered long hairs in the leaves of young branches, varying in length from 2 to 9 and sometimes even 15 inches and in breadth about 1/8 inch or less. [Illustration: Fig. 198.--Chloris virgata. 1. Spikelet; 2 and 3, the first and second glumes; 4 and 5. the third glume and its palea; 6. lodicules, stamens and the ovary; 7. the fourth glume; 8. grain.] The _inflorescence_ consists of from four to nine spikes digitately arranged on a long peduncle and the leaf-sheath enclosing the inflorescence is somewhat large and inflated. Spikes are 1 to 1-1/2 inches long with fine, angular rachis, scaberulous in the edges. _Spikelets_ are about 1/10 inch, 2-awned, shortly stalked and consist of only four _glumes_. The _first glume_ is small lanceolate, glabrous, with the keel scaberulous, 1-nerved. The _second glume_ is about one and a half times the first, oblong-lanceolate, 2-fid at the apex, glabrous, but the keel scaberulous and nerve produced between the lobes into a short scaberulous awn. The _third glume_ is oblong-ovate, lanceolate, 2-fid at the apex, and awned in the sinus, awn being about 1/4 inch long bearded at the base, the margins are slightly ciliate up to about the middle and then closely ciliate with long hairs almost to the tip, but not to the tip; on the two sides of the dorsal nerve there are two shallow grooves one on each side, with short scattered appressed hairs; the palea is narrow oblanceolate, minutely 2-fid at the tip, with margins folded inward and embracing the _stamens_, _ovary_ and the _lodicules_. Grain is narrow, trigonous, oblong, translucent and shining. The _fourth glume_ is borne by a short rachilla which is about 1/3 the length of the third glume or less, shorter than the third, cuneiform, empty and awned. This grass grows well and produces a fair amount of foliage. _Distribution._--This is not very common. So far collected only from Hosur in Salem district and Bellary district
