internodes £-1 lin. long ; pedicels solitary, extremely short, setu- 
losely bearded, setules 1J lin. long. Spik elets closely contiguous, 
broad-oblong, obtuse or subacute, up to over 2J lin. long, greyish- 
green with a usually deep-purple lower glume, silky hirsute. Glumes 
membranous, equalling the spikelet or the lower slightly shorter ; 
the lower broad-oblong, clasping the lower floret, emarginate, glabrous, 
11-nerved, with very few cross-veins upwards ; upper similar to the 
lower if not broader, 9-7-nerved, with more numerous prominulous 
cross-veins, loosely hirsute, the hairs white, appressed, longer upwards 
and exceeding the tip of the glume. Lower floret almost as long 
as the glumes : valve similar to the glumes, 5-nerved, with numerous 
cross-veins, glabrous along the middle, otherwise hairy like the 
upper glume ; valvule as long as the valve, broad-oblong, acute, 
keels hardened, more or less recurved upwards ; anthers 1J lin. 
long. Upper floret oblong, obtuse or minutely apiculate, con- 
stricted at the base, 1J lin. long, milk-white, more or less glossy ; 
valve and valvule crustaceous, obscurely pitted,. — Panicum dicty-

or geniculately ascending, terete or somewhat compressed, 4-5- 
noded, simple, glabrous, internodes exserted. Leaves 8-9, rather 
crowded at the base ; sheaths rather tight, compressed, smooth 
and glabrous, the basal rather short ; ligules a ciliolate mem- 
branous rim ; blades linear from an equally broad base, gradually 
tapering to an acute point, 2-4 in. by 2J lin., subconvolute,* pale 
green, glabrous or somewhat hairy on the upper side near the base 
and pubescent at the junction with the sheath, rigid, pungent, 
margins cartilaginous, the outer remotely serrulate, the inner smooth, 
primary nerves about 4 on each side, inconspicuous. Inflorescence 
of 2 secund suberect spiciform racemes, the lower subsessile, reaching 
up to the base of the other ; common axis very slender, flat, glabrous 
and smooth, purple-brown. Racemes simple, 2-seriate, about 2 in. 
long ; rhachis very slender, flat, glabrous except at the pubescent 
base, purple-brown or blackish, internodes about 2 lin. long ; pedicels 
solitary, more or less curved, up to J lin. long, with swollen tips and 
stiff yellowish setules, about 3 lin. long. Spikelets contiguous,
