Spikes narrowly winged; spikelets subsilky with slender (not clavellate) hairs 4. D. longiflora. [Illustration: Fig. 71.--Digitaria sanguinalis, _Var. ciliaris_.] =Digitaria sanguinalis, _Scop._= _Var. ciliaris._ This is an annual grass either with erect tall stems or long prostrate stems, varying in length from 1 to 3 feet or more. The _leaf-sheath_ is herbaceous, loose and glabrous. The _ligule_ is a distinct membrane. The _nodes_ are glabrous. The _leaf-blade_ is linear-lanceolate or linear, flat, glabrous or very sparsely hairy, varying in length from 2 to 5 or 6 inches and in breadth from 1/6 to 1/3 inch. The _spikes_ are usually few, 2 to 6, 3 to 6 inches long, with a triquetrous, narrowly winged rachis. The _spikelets_ are oblong, acute, binate, one pedicel being shorter than the other, usually appressed to the rachis and not spreading. [Illustration: Fig. 72.--Digitaria sanguinalis. _Var. ciliaris_. 1. A portion of the spike showing the binate spikelets; 2. a spikelet; 3. the minute scale-like first glume; 4, 5 and 6. the second, third and the fourth glume, respectively; 7. the palea of the fourth glume.] There are four _glumes_ including the minute glume. The _first glume_ is a very minute scale. The _second glume_ is about half as long as the third glume, membranous, usually 3-nerved and sometimes 3- to 5-nerved, distinctly ciliate. The _third glume_ is oblong-lanceolate, acute, membranous, 3- to 5-nerved, sparingly hairy in the lower spikelet and densely bearded with soft spreading hairs in the upper spikelet. The _fourth glume_ is lanceolate, or oblong-lanceolate, acute, somewhat chartaceous, paleate; _palea_ is like the glume in texture. _Anthers_ are pale yellow. _Stigmas_ are white. There are two small cuneate _lodicules_. This is an excellent fodder grass. It grows well in all kinds of soils, rich or poor, and is very common in dry fields brought under cultivation. _Distribution._--Throughout India. =Digitaria sanguinalis, _Scop._= _Var. Griffithii._ This is an annual with stems ascending from a prostrate or geniculate base, glabrous and varying in length from 1 to 3 feet. The _leaf-sheath_ is glabrous, thinly herbaceous and loose. The _ligule_ is a distinct membrane and the _nodes_ are glabrous. The _leaf-blade_ is linear or linear-lanceolate, flat, acuminate, varying in length from 2 inches to 12 inches and in breadth 1/6 to 1/3 inch. The _inflorescence_ is of several slender spikes, usually drooping, 2 to 4 inches; the rachis is filiform and trigonous. The _spikelets_ are linear-lanceolate, solitary or in distant pairs, glabrous or ciliate, pedicelled and when binate the upper pedicel often longer than the spikelets, usually spreading and not appressed to the rachis.
