The _leaf-sheath_ is short, smooth, compressed with scattered long hairs at the mouth. The _ligule_ is a narrow membrane with the edge cut into narrow lobes. The _leaf-blade_ is flat, linear, acute or subacute, scaberulous, 1/3 to 3-1/2 inches long, 1/8 to 3/16 inch broad. [Illustration: Fig. 195.--Cynodon Barberi. 1. Front and back view of a portion of spike; 2. a single spikelet; 3. a spikelet with the flower out; 4. the third glume, its palea and the produced rachilla with a minute glume; 5. clavellate hairs; 6. ovary; 7. lodicules; 8. grain.] The _inflorescence_ consists of three to five digitate spikes, 3/4 to 1-1/2 inches long, erect or spreading, pale green or purplish. The _spikelets_ are compressed laterally, sessile or obscurely pedicelled, imbricate, alternately biseriate on the ventral side of the rachis, 1-flowered; the _rachilla_ is produced into a bristle behind the palea, with or without a minute glume. There are three _glumes_. The _first glume_ is lanceolate, acute, shorter than the second, with a keel which is scabrid. The _second glume_ is lanceolate, acuminate, equal to or a little longer than the third glume with a scabrid keel. The _third glume_ is obliquely oblong to ovate, subacute, truncate or 2-toothed, boat-shaped, sub-chartaceous, 3-nerved, paleate and distinctly keeled; the keel and the margins of the glume are densely covered with distinctly clavellate hairs; _palea_ is firmly membranous, equal to or slightly smaller than the glume, linear-oblong, 2-keeled, densely hairy with clavellate hairs along the keels, and 2-nerved. There are two _lodicules_ and three _stamens_. The _ovary_ is ovoid with two style branches. Grain is free within the glume, oblong, smooth, transparent, and the embryo is about one-third the length of the grain. This species is closely allied to _Cynodon dactylon_, Pers., but differs from it in the following respects:--The absence of stoloniferous underground branches, leaves short and not finely pointed; spikes not exceeding five; the _second glume_ is always equal to or longer than the _third glume_; presence of clavellate hairs on the keels and margins of the third glume and on the keels of the palea. _Distribution._--So far collected in Coimbatore, Salem, Tinnevelly, Chingleput and Godavari districts. 36. Chloris, _Sw._ These are annual or perennial grasses. Spikes are solitary or many in terminal umbels or short racemes, erect or spreading. Spikelets are unilateral, sessile, crowded, biseriate on a slender rachis with four to six glumes and 1 to 3-flowered; the rachilla is produced and disarticulating above the empty glumes. The first two glumes are unequal, narrow, keeled, membranous, 1-nerved, persistent, acute, mucronate and the second glume awned shortly. Floral glumes narrow or broad, acute, obtuse or minutely 2-toothed and awned, paleate; sterile glumes are small, without palea. There are two lodicules and anthers are rather small. Grain is narrow and free.
