There are three glumes. The _first glume_ is concave, 3- to 5-nerved (rarely 3- to 7-nerved). The _second glume_ is flat, 5-nerved, with two strong sub-marginal nerves, sometimes with shallow transverse pits along the margins. The _third glume_ is thickly coriaceous, brownish, shining, minutely striolate, margins roundly incurved throughout its length, paleate; the _palea_ is similar to the glume in structure and colour, margins strongly inflexed and with two broad membranous auricles almost overlapping just below the middle. There are three _stamens_. The _stigmas_ are white both when young and while fading. The style branches are diverging widely and then straight. There are two oblong cuneate fleshy _lodicules_. [Illustration: Fig. 70.--Paspalum scrobiculatum. 1 and 2. Front and back view of a portion of spike; 3, 4 and 5. spikelets; 6, 7 and 8. the first, second, and the third glume, respectively; 9. palea of the third glume; 10. the ovary, stamens and the lodicules.] This grass flourishes all over the Presidency in moist places, such as, bunds of wet lands, edges of ponds and lakes and in marshy land. There are two forms of this grass, one with round and another with ovate oblong spikelets. They also vary in the size of the spikelets--some forms have small spikelets and others large. Sometimes the spikelets show variation in the number of glumes. This grass is also cultivated for its grain. In cultivated forms the spikelets are larger and the whole plant grows bigger. It is grown both in wet and dry land. _Distribution._--Throughout India (wild and also cultivated). 2. Digitaria, _Rich._ Annuals or perennials. The spikelets are lanceolate, 2- to 3-nate, in digitate or racemose spikes, jointed on the pedicels but not thickened at the base, 1-flowered. There are usually four dissimilar glumes in the spikelet. The first glume is hyaline very minute, sometimes absent in the same species. The second glume is membranous, 1- to 5-nerved or nerveless. The third glume is membranous, almost equal to the fourth, usually 7- to 9-nerved, the nerves being straight, close, parallel and prominent, with a minute palea or without a palea. The fourth glume is chartaceous or sub-chartaceous, usually 3-nerved and paleate; palea is equal to and similar to the fourth glume, 2-nerved. Lodicules are two, small, broadly cuneate. Stamens are three. Styles are distinct with plumose stigmas exserted laterally near the apex of the spikelet. Grain is enclosed in the fourth glume and its palea. KEY TO THE SPECIES.
