The _leaf-blade_ is soft, narrowly linear, finely acute, acuminate or pungent, somewhat glaucous, conspicuously distichous at the base of the stem and, in non-flowering branches, scabrid along the margins. The _inflorescence_ consists of two to eight smooth, digitate, green or purplish spikes, 1 to 3 inches long; _rachis_ is slender, compressed or angular, scaberulous. [Illustration: Fig. 191.--Cynodon dactylon. 1. A portion of spike, front view; 2. back view of a bit of spike; 3. spikelet; 4. first glume; 5. second glume; 6. third glume; 7. palea of third glume and rachilla; 8. lodicules, ovary and anthers; 9. hairs on the margin and keel of third glume.] _Spikelets_ are laterally compressed, sessile, imbricate, arranged alternately in two series along one side of the rachis; _rachilla_ produced beyond the first two glumes and hidden at the back of the palea between the two keels, small, slender and blunt when old and with a membranous imperfect glume when young, less than half the length of the spikelet. There are three _glumes_. The _first_ and _second glumes_ are shorter than the third, empty, ovate-lanceolate, acute, membranous with one thick green nerve in the middle, keeled, upper margin and keel scaberulous. The _second glume_ is usually a little longer than the first, but occasionally also slightly shorter than the first. The _third glume_ is longer than both the first and second glumes, obliquely oblong to ovate, subacute, membranous, boat-shaped, smooth, keeled, 3-nerved, one central along the keel and two marginal, keel scabrid below with stiff pointed hairs above, tip and lower margins scabrid or pilose, _palea_ linear oblong, a little less than the third glume, obtuse, 2-nerved and with two scabrid keels. _Stamens_ are three with pale purple anthers. _Lodicules_ are two. Stigmas are purplish. Grain is oblong, slightly flattened, dorsally rounded, dull reddish-brown. This is the common Hariali grass. It is also called "Devil's grass." _Distribution._--It is cosmopolitan. [Illustration: Fig. 192.--Cynodon intermedius.] =Cynodon intermedius, _Rang. & Tad._= This grass is a widely creeping perennial. The stems are slender, glabrous, creeping superficially and rooting at the nodes, but never rhizomiferous, leafy with slender erect or geniculately ascending flowering branches, and varying in length from 12 to 18 inches. _Nodes_ are slightly swollen, glabrous, green or purplish. The _leaf-sheath_ is smooth, glabrous, slightly compressed, sparsely bearded at the mouth, shorter than the internode, except the one enclosing the peduncle which is usually long. The _ligule_ is a shortly ciliated rim. The _leaf-blade_ is linear, flat, finely acuminate, scaberulous above and along the margins, smooth below except in some portions of the midrib, 1/2 to 7 inches in length and 3/16 to 1/4 inch in breadth.
