CLVII. GRAMINEiB (Stapf). 
[Panicum. 
obliquely erect, flat, thin, somewhat rigid, green, minutely and 
appressedly hairy to subglabrescent, with minutely tubercle-based 
hairs, margins scaberulous, midrib fine, whitish below, primary 
lateral nerves very fine, 3-4 on each side, distant, with 4-6 secondary 
nerves in the intervals and fine cross- veins. Panicle emerging from 
the uppermost sheath, widening out upwards, up to 6 in. long, 
divided to the fourth degree ; common axis very slender, angular, 
smooth below, like all its divisions scaberulous to scabrid upwards 
with a few fine long hairs here and there ; internodes short low down, 
then §— | in. long ; lower branches finely filiform, up to over 3 in. long, 
divided like the secondary branches from the base or some distance 
above it, the latter subcapillary, 3-4 lin. apart, its divisions up to 
4 or 5 lin. long, bearing 4-1 much scattered spikelets or in the lower 
part of the panicle barren, with small arrested spikelets ; pedicels 
capillary, J-1J (rarely the terminal 3) lin. long. Spikelets acutely 
lanceolate to lanceolate-oblong in back view, slightly oblique in 
profile, 1 lin. long, pale or greyish-green, loosely pubescent from the 
glumes. Glumes equally long, thinly membranous, very finely 
and prominently nerved ; lower broad-lanceolate, acuminate, 
3-nerved ; upper corresponding in length and outline to the spikelet 
(as seen in back view), rather concave, rounded on the back, 5-nerved. 
Lower floret barren : valve similar to the upper glume, but glabrous 
and less concave, equalling it or very slightly shorter ; valvule more 
or less reduced, keels scaberulous. Upper floret lanceolate- 
oblong, acute, £ lin. long, whitish, smooth.

79. P. Ilochstetteri, Steud. Syn. PI. Glum. i. 90. Perennial, 
loosely csespitose from a slender rhizome, from J to over 1 ft. long. 
Culms very slender to filiform, erect from a much- branched base, 
above it simple or sparingly branched, many-noded, terete, glabrous, 
smooth, lower nodes enclosed, upper shortly, uppermost long- 
exserted. Leaf-sheaths tight, terete, finely striate, ciliolate, other- 
wise glabrous or sparingly pubescent upwards, the basal very short, 
the uppermost up to 2| in. long ; ligule reduced to a ciliolate rim ; 
blades reflexed, often strongly so, linear from a slightly rounded base, 
tapering to a very slender somewhat blunt point, up to 3 in. by 2 lin., 
those of the basal shoots often much smaller, green, flat, more or less 
involute, particularly upwards, glabrous and smooth below or both 
sides loosely and shortly hairy, margins scaberulous, midrib and 
primary lateral nerves 2-3 on each side, very fine but distinct below 
only. Panicles long-exserted, widely open and loose, 2-3 in. by 2 to 
over 3 in. , divided up to the third or fourth degree ; common axis 
filiform, like all its divisions terete, glabrous and smooth or almost so, 
and more or less flexuous or wavy upwards, often purplish, lower 
internodes up to 6-8 lin. long, mostly much shorter or the lowest
