The _leaf-sheath_ is glabrous and close. The _ligule_ is a short, fimbriate membrane. _Nodes_ are glabrous. The _leaf-blade_ is narrow, flat, acuminate, glabrous on both sides, 3 to 10 inches long. The _panicle_ is erect, narrow, contracted, with branches in pseudo-whorls and varying in length from 6 to 18 inches, branches are slender, filiform, two or more arising from the same level, 1 to 3 inches long. The _spikelets_ are small, pedicellate, smooth, usually 6 to 14-flowered, pale but often tinged with red, the rachilla is jointed between the flowering glumes, and breaks away from above downwards. The empty _glumes_ are very small, subequal, ovate-oblong, hyaline, obtuse and 1-nerved. Floral _glumes_ also are small but slightly longer than the empty ones, ovate-oblong, obtuse and paleate, palea is linear-oblong with smooth or scabrid keels. _Stamens_ are two with small anthers. Grain is obovoid. [Illustration: Fig. 217.--Eragrostis interrupta. Var. Koenigii. 1. Two spikelets; 2 and 3. empty glumes; 4. empty glumes with two flowering glumes and their palea; 5. flowering glumes and palea; 6. ovary and two stamens; 7. grain.] This grass is a very variable plant and has a few varieties. The one described above is Var. _Koenigii_ Stapf., and this is the one that occurs very widely. The other two varieties which occur very rarely are (1) _diarrhena_ Stapf. and (2) _tenuissima_ Stapf. The former is a tall plant with very narrow panicle and spikelets and the latter either tall or short and with a panicle bearing very slender divaricate branches. This grass usually occurs in clayey soils especially on the bunds and in the paddy fields. _Distribution._--Throughout India, Burma and Ceylon. Also in tropical Asia and Africa. =Eragrostis amabilis, _W. & A._= This is an annual tufted grass with slender, glabrous, erect or geniculately ascending stems, 6 to 18 inches, leafy chiefly at the base. The _leaf-sheath_ is glabrous and smooth. The _ligule_ is absent or very obscure. The _leaf-blade_ is lanceolate-linear or linear, narrowed from a broad subcordate base to an acute tip, smooth and flat. The _panicle_ is ovoid-oblong or oblong, open or contracted, sparingly branched; branches are fi
