stinct. _Ovary_ has two styles with feathery _stigmas_ white at first, but turning deep purple while withering. This delicate and small grass occurs here and there as mere tufts especially in sheltered situations. It usually flourishes in black cotton soils amidst cholam (_Andropogon Sorghum_), although it thrives equally well in other rich soils. This is considered to be a very good fodder grass. _Distribution._--It is fairly common all over the Madras Presidency, and goes up to 3,000 or 4,000 feet. It occurs in Africa, America and Italy. [Illustration: Fig. 82.--Panicum flavidum.] =Panicum flavidum, _Retz._= This plant is a tufted annual. It branches freely from the base; branches are tufted, decumbent at first but soon becoming erect, slender, glabrous, compressed and leafy, varying in length from 1 to 3 feet. Leaves are somewhat distichous. The _leaf-sheath_ is compressed, glabrous, sometimes with a tinge of purple, the lower ones swollen at the base and the mouth is hairy. The _ligule_ is a fringe of hairs. Nodes are glabrous. The _leaf-blade_ is flat, thinly coriaceous, linear-lanceolate and acuminate, or ligulate with a rounded tip, 3 to 5 inches in length, 3/16 to 5/16 inch wide, glabrous or very thinly scaberulous, base rounded or slightly cordate with long white ciliate hairs on the small basal lobes. [Illustration: Fig. 83.--Panicum flavidum. 1 and 2. Front and back view of a portion of spike; 1a and 2a. the front and back view of a spikelet; 3 and 4. the first and the second glume, respectively; 5 and 5a. the third glume and its palea; 6 and 6a. the fourth glume and its palea; 7. anthers and ovary; 8. grain.] The _inflorescence_ is a raceme of spikes, 5 to 10 inches long, erect or inclined on a short or long, glabrous, strongly channelled peduncle; the main rachis is grooved, angled and scaberulous. _Spikes_ are few or many, 1/4 to 1 inch long, erect, pressing on the rachis of the inflorescence along the groove, distant and sessile; the lower spikes are very much shorter than the internodes, but the upper equal to or longer than the internodes; the rachis of the spike is angular, flattened below, erect or slightly recurved. The _spikelets_ are white, in two rows on a flattened rachis, obliquely ovoid or gibbously globose, glabrous, sessile, 1/8 inch in length. There are four _glumes_. The _first glume_ is suborbicular, about half the length of the third glume, usually 3-nerved. Th
