3. V. fulvibarbis^ Stapf. Culms moderately stout, sparingly 
branched, up to 6 ft. high, most of the middle and upper nodes 
exserted. Leaves very similar to those of the two preceding species, 
but rather smaller or at least narrower. Panicle oblong, 4-8 in. by 
1J-2 in., slightly contracted, erect or more often slightly nodding 
and secund ; rhachis slender, smooth ; whorls 6-8 with up to over 
12 rays ; branches obliquely erect, usually slightly curved, naked 
for up to 1J in., finely filiform, smooth or slightly rough. Racemes 
up to 2 in. long, very slender ; joints 3-4 lin. long, tips very oblique, 
very minutely ciliolate, smooth; pedicels similar but shorter. Sessile 
spikelet subulate-linear (seen from the back), acuminate, 3-4 lin. 
long, pale ; callus up to § lin. long, acute, fulvously bearded on the 
sides and at the base of the upper glume, hairs up to 1 lin. long. 
Glumes subcoriaceous ; lower rigidly ciliate or ciliolate on the sides, 
smooth on the back except sometimes towards the rough tips, finely 
3-5-nerved ; upper glume similarly ciliate from the keel, aristulate 
from the minutely 2-dentate tip, reversedly ciliate along the margins, 
faintly 3-nerved. Valve of lower floret almost as long as the glumes,
