7. R- acuminata, 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. 



Tbe Deccan PekinsulA, 0. Thomson ; N. Canara ; Carwar, Talbot. 



Stem 3-12 in. , ascending from a creeping base, compressed, leafy. Leaves 

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

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

 short, truncate, glabrous. Spikes 1-2 in. j joints subdavate, much shorter than the 

 sessile Bpikelets, base not excised. Sessile spiielets ^-i in,, callus obscure ; gl. I 

 6-nerTed in the narrow coriaceous part between the wings ; II elliptic-lanceolate, 

 acute, S-nerved ; 111 elliptic, paleate, male ; IV short, oblong, obtuse ; palea small, 

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

 tubercled; II S-neryedj IT male, lanceolate, many times longer than the joint. 



Yar. 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. — Malwar, 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. dlvergrenS) Satk. 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.

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

 flowering branches. Leaves IJ— IJ in., narrowly linear, hairy beneath and on the 

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

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

 excised, outer margins of the cavities ciliate. Sessile spikelets ■YS'i '"•> broadly 

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

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

 sometimes as long as tbe spikelet ; II shorter, ovate, acute, keeled, 3-nerved, III 

 broadly ovate, nerveless, empty ; IV =111, ovate-oblong, obtuse, nerveless. Pedicelled 

 spikelets lanceolate ; gl. I smooth, 6-nerved, broadly inflexed on one side with a 

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

 pedicel adnata. — 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 tbe 

 nerves.

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

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

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

 the raohis.
