10. H. Nyassse^ Stapf. Perennial, up to over 2 ft. high, very 
densely tufted, with numerous intravaginal innovations. Culms 
erect, slender, terete, glabrous and smooth, simple and about 3- 
noded below the panicle. Leaf-sheaths terete or those of the 
innovations more or less keeled, firm, the basal packed inside with 
wool, long persistent, the upper sparingly hairy or glabrous ; ligule 
short, truncate, scarious ; blades of the innovation-leaves very 
narrowly linear, 9 in. by less than 1J lin., flat, firm, subglaucous, 
at length reddish, usually bearded at the mouth and often hairy above 
it, those of the culm-leaves shorter and relatively broader, mostly 
glabrous or sparingly bearded at the base ; midrib slender, lateral 
nerves about 3, very slender. Spatheate panicle J-l ft. long, 
of 3-4 distant 1-3-rayed simple tiers ; rays slender, filiform, 
4-5 in. long ; subtending leaves spathaceous upwards with rapidly 
decreasing blades or quite spatheoloid. Spatheoles narrowly 
lanceolate, long-acuminate, 2-3 in. long, glabrous, scarious, reddish 
or purplish and often subglaucous, at length narrowly inrolled ; 
peduncles narrowly filiform, at first laterally, then terminally or 
subterminally and often very long-exserted from the spatheoles, 
curved below the tips with long spreading tubercle-based hairs 
from the curvature . Racemes somewhat slender, nodding, ultimately 
spreading or epinastically reflexed, f-1 in. long, 7-13-awned per 
pair, fulvously silky, the lower subsessile, the other with a slender 
filiform base, 1J-1J lin. long, pubescent in the fork, otherwise 
glabrous ; . joints very slender, filiform, very obliquely truncate 
to subauriculate, about 1J lin. long, shortly and densely ciliate, 
cilia fulvous ; pedicels very similar but rather longer and more 
slender, and produced into a small linear auricle. Homogamous 
pair of spikelets 1 at the base of the lower raceme only. Fertile 
spikelets oblong, subacute, 2J-2| lin. long, pale or purplish except the 
hairs ; callus short, subacute, very shortly bearded. Glumes equal, 
lower subchartaceous, minutely truncate, dorsally flattened, margins 
very narrowly involute or indexed below the tips and there forming
