re from 1/2 to 2 inches; _rachis_ is slender, flexuous, flattened, scaberulous, with a few long hairs scattered singly along the margins or without these hairs. [Illustration: Fig. 98.--Panicum distachyum. 1 and 2. Front and back view of a portion of a spike; 3, 4, 5, and 6. the first, second, third and the fourth glume, respectively; 5a and 6a. palea of the third and the fourth glume, respectively; 7. anthers and ovary.] The _spikelets_ are glabrous, ovate-oblong, acute, 1/8 inch, 1- or 2-seriate, subsessile, pale green, occasionally purplish on one side. There are four _glumes_. The _first glume_ is membranous, broadly ovate, obtuse with margins overlapping at the base, hardly half the length of the third glume, usually 5-nerved but occasionally 7-nerved. The attachment of the first glume is not close to that of the second glume but is far lower. The _second glume_ is ovate-acute, 7-nerved. The _third glume_ is equal to the second, 5-nerved, paleate, empty; the _palea_ is narrow, hyaline, acute. The _fourth glume_ is ellipsoidal, obtuse, chartaceous, minutely and obscurely rugulose, faintly 3-nerved, with the base somewhat thickened. _Palea_ is similar to the glume in texture. _Anthers_ are orange-yellow. _Lodicules_ are minute and fleshy. Style branches are purple. This grass is fairly common in open and loamy and sandy soils. The form (var. _brevifolium_, Wight & Arnott) is fairly common in Coimbatore District. _Distribution._--Plains of India and Ceylon. Not recorded from the Bombay Presidency. It occurs in China, Malaya and Australia. [Illustration: Fig. 99.--Panicum interruptum.] =Panicum interruptum, _Willd._= This is a large perennial grass with stems reaching 5 to 6 feet in length, flourishing in marshes and in the edges of ponds and tanks. The stems are long, stout and spongy below, ascending from a creeping and rooting or floating root-stock; the lower internodes are often 1/2 inch or more in thickness, with nodes bearing in fascicles long stout roots clothed with fine lateral roots; and the upper internodes are long and slender. The _leaf-sheath_ is glabrous, striate. The _ligule_ is a short broad membrane. The _leaf-blade_ is soft, flat, many-nerved, linear, finely acuminate, margins smooth, base rounded or subcordate, glabrous, 6 to 12 inches long, 1/4 to 1/2 inch broad. The _inflorescence_ is a strict spike-like panicle, 6 to 12 inches long by 1/4 to 1/3 inch broad, cylind
