Stem tall, erect like A. Boyleanus, or low and densely tufted. Leaves 1-3 in., 

 glabrous or hairy. Spihes J-IJ in., slender or stout. Spikelets J— | in.; gl. I 

 yellow with red-brown tips, or dark brown with yellowish tips, glabrous or clothed 

 with red-brown shiny hairs, tips retuse ciliate with minute or long hairs j II 

 3-nervedor nerveless, sides sharply inflected, angles smooth or scabrid; III nearly 

 = I, tip ciliolate ; IV very narrowly oblong or almost linear, awn two to six times 

 as long as the spikelet; palea very short and convolute. — Very variable, and 

 doubtfully separable from Boi/leanus which is stouter with stouter spikes. Wight's 

 original , specimen (Cat. n. 2352) is 18-20 in. high, very slender, leafy upwards, 

 with slender pale spikes, and glabrous gl. I; it strongly resembles some specimens 

 of Itoyleanus, and is I suspect perennial. This and a var. zeylanicws {Wightii, 

 Thw.) with more hairy, darker gl. I, forms Hackel's Subsp. genumus. His Subsp. 

 mangalurensis includes short densely tufted states, with shorter red-brown densely 

 hairy and loiig-ciliate gl. I ; it is the common Deccan form, and includes Thwaites' 

 A., Bechettii. The difference between the narrow gl. IV of all states of A. 

 Wigita, and the much broader hyaline one of A. B^oyleanus, is one of degree only.

Stems slender, stiff, widely creeping and rooting, with short geniculately ascend- 

 ing flg. branches, 2-6 in. high. Le:ii>es 1—2 in., linear, acuminate, smooth, sparsely 

 hairy, margins thickentd, suhscaberulous ; sheath open ; ligule 0. Spikes J-l in. 

 i in. diam., very pale ; rachis slender, ciliate. Spikelets -^ in.j gl. I broadly cunei- 

 form, ciliate with long hairs, 7-9-nerved ; II oblong, obtuse, 3-nerved, lateral nerves 

 Bubmarginal, keels ciliate ; III oblong or lanceolate, glabrous, nerveless ; IV awn 

 \-l in., brown, not dilated at the base ; palea 0. Pedicelled spikelets, gl. I spathulate, 

 truncate, villous, sides recurved ; II as in the sessile spikelets.

Annual or perennial slender grasses. Leaves short, liroad, deeply 

 cordate. Spikelets 1-fld., solitary or with a rudimentary pedicellea 

 second, sessile on binate digitate or fascicled jointed spikes. Glumes 4, 

 I largest, usually strongly tubercled, not embracing the inner ; II keeled, 

 3-nerved ; III small, hyaline ; IV shortest, lanceolate, keeled, hyaline, 

 with usually a long dorsal or basal awn; .palea minute or 0. Lodicules 

 subqaadrate. Stamens 2-3. Styles short or 0, stigmas long, laterally 

 ■exserted. Grain narrowly linear. — Species 8, tropics of Old "World.
