Throughout India j from Nepal and the Khasia Hills to the Deecan, Burma and 

 the Nicobar Islds. (not in Ceylon). — Uistkib. Malay Islds., Japan, Trop. Austral. 



Annual, much branched, leafy. Leaves 1-3 in., erect; sheaths glabrous or 

 pilose. Spikes 2, rarely 3; rachis about as broad as the spikelets, margins 

 scaberulous, costa strong. Spikelets linear, acuminate, callus villous ; gl. I slender, 

 nearly glabrous j III short, acute j palea 0. — Hiickcl has 6 varieties of this species, 

 of which more might be made. 



5. D. Woodrowiij Btapf in Hooh. Ic. PI. t. 2312 ; spikea. 2 circin- 

 ately involute, rachis rigid glabrous, spikelets very shortly pedicelled, 

 callus shortly bearded, gl. I and II subequal acute, III linear hyaline, IV 

 shortly awned. 



The CoNCAN; Batnagherry district, and near 6oa, Wbodrow. 



Annual. Stem 3-6 in. slender, leafy to the top, simple or sparingly branched ; 

 upper internode (or peduncle) with its leaf abruptly deflexed after flowering. 

 Leaves 2-3 in., linear, acuminate, erect, strict, glabrous or sparsely hairy ; ligale 

 very short, hyaline. Spikes f-1 in., at first erect, rachis dorsally convex, concave 

 ventrally. Spikelets few, rather distant, suberect, divergent as the rachis incurves; 

 gl. I glabrous or sparsely hairy ; awn of IV about twice as long as its glume ; palea 

 0. — A very peculiar species, at once recognized by the two spikelets forming together 

 a hoop. 



6. D. connivens, Hach. Monogr. Androp. 689 ; annual, i-achis of spike 

 nearly as broad as the spikelets ciliate, spikelets J in. subsessile, callus
