7. R. a cumin at a, Hack. Monogr. Androp. 291 ; annual, spikes short, 

 gl. I of sessile spikelet broadly ovate acuminate winged above the middle, 

 coriaceous below it with 3 to 6 dorsal transverse echinulate or warted 

 ridges. 



The DECCAN PENINSULA, Q. Thomson ; N. Canara ; Carwar, Talbot. 



Stem 312 in. , ascending from a creeping base, compressed, leafy. Leaves 

 flaccid, lower 2-3 in., linear-lanceolate from a narrow base, acuminate, upper shorter 

 spreading and recurved ; sheath turgid, compressed, keeled, mouth hairy ; ligule 

 short, truncate, glabrous. Spikes 1-2 in. ; joints subelavate, much shorter than the 

 sessile spikelets, base not excised. Sessile spikelets \-% in., callus obscure ; gl. I 

 5-nerved in the narrow coriaceous part between the wings ; II elliptic-lanceolate, 

 acute, 3-nerved ; III elliptic, paleate, male ; IV short, oblong, obtuse; palea small, 

 2-lobed, nerveless. Pedicelled spikelet ; gl. I winged on one side, 5-nerved, base not 

 tubercled ; II 3-nerved; IV male, lanceolate, many times longer than the joint. 



Var. Stocksii ; diffusely branched from the root, gl. I of pedicelled spikelet | in. 

 subulate-lanceolate erect or recurved narrowed into a slender scaberulous awn not or 

 obscurely winged. Mai war, Stocks. The long gls. of the pedicelled spikelets give 

 this variety a very different appearance, but intermediates occur, and the specimens 

 were mixed with those of R. acuminata proper. 



8. R. divergrens, Hack. Monogr. Androp. 293; annual, spikes short, 

 gl. I of sessile spikelet crossed below the middle with echinulate ridges 

 ovate 2-mucronate or 2-aristate with broad hyaline wings above the middle.

EAST INDIES, Huegel. The CONCAN and CANAEA; Belgaum, Ritchie; Satara 

 and Mahableshwar, Lisboa. 



Stem 4-10 in., erect or ascending, slender, terete, nodes 2-3 all with 2-nate 

 flowering branches. Leaves 1^1^ in., narrowly linear, hairy beneath and on the 

 margins; sheath compressed, naked, hairy; ligule short, membranous, rounded. 

 Spikes about f in., slender, erect, pale; joints shorter than the spikelets, subclavate, 

 excised, outer margins of the cavities ciliate. Sessile spikelets tVi in., broadly 

 oblong, dorsally with 7 lines of small pits (Hackel) or rugose with long or short 

 transverse tubercled or echinate ridges or crests, mucros or awns erect scabrid 

 sometimes as long as the spikelet; II shorter, ovate, acute, keeled, 3-nerved, 111 

 broadly ovate, nerveless, empty ; IV = 1II, ovate-oblong, obtuse, nerveless. Pedicelled 

 spikelets lanceolate ; gl. I smooth, 5-nerved, broadly inflexed on one side with a 

 winged keel, on the other produced into a mucro ; II lanceolate, acute, keel winged; 

 pedicel adnate. The ridges on gl. I of the sessile spikelet are very variable, and 

 are sometimes replaced as it were by vertical rows of incurved spinules on the 

 nerves. 



9. R. Talboti, HooJc. f. (non Lisboa); annual, leaves linear, spikes 

 solitary short, gl. I of sessile spikelet lanceolate narrowed into a slender 

 scabrid awn, and with 3 transverse ciliolate ridges towards the base 

 broadly winged above it, pedicel of upper spikelet adnate to the joint of 

 the rachis. 



GOA DISTEICT, Talbot. 



Stems 6-8 in , slender, erect or base geniculate, subsimple. Leaves 2-3 in., 

 narrow, smooth; sheath glabrous; ligule short, membranous. Peduncles 2-3 in., 

 rery slender, flexuous. Spikes % in. diam., green, joints very short, tumid, excavate 

 opposite the spikelet, top broad, cavity very large, margins thick hispidulous. 

 Spikelets closely imbricating, in. long including the awn ; callu* annular, ciliolate ; 

 gl. I of sessile spikelet many-nerved on the coriaceous disk; II much short* r, hyaline, 

 ovate-oblong, acute, 1-nerved ; 111 broadly oblong, tip rounded, faintly 3-nerved, 

 male ; IV small, oblong, obtuse, nerveless, palea as long nerveless. Pedicelled
