clvii. gramine^ (Stapf). [ Hyparrhenia . 
lateral nerves 3-5 on each side, slightly raised. Spatheate panicle 
scanty, about 8 in. long, of few- to 6-rayed tiers, all the rays simple ; 
spathes bladeless, narrow, tapering to a long fine point, up to over 
4 in. long, subherbaceous, subglaucous, glabrous or very sparingly 
hairy ; rays filiform, about 2 in. long. Spatheoles subulate-lanceo- 
late, glabrous, otherwise resembling the spat he, at length tightly 
inrolled ; peduncles finely filiform, recurved upwards, more or less 
exserted from the spatheoles, pubescent upwards with some long 
fine spreading hairs. Racemes slightly spreading, very loose, pale, 
fulvously silky, 1 in. long, 7-8-awned per pair ; raceme bases very 
slender, filiform, the lower 1 lin., the upper up to 4 lin., pubescent 
below ; joints filiform, obliquely truncate, about 2 lin. long, shortly 
ciliate, cilia whitish below, more or less fulvous upwards ; pedicels 
very similar, with a small subulate auricle. Homogamous pair of 
spikelets 1 at the base of each raceme or 2 at that of the upper. 
Fertile spikelets linear-oblong, including the callus 2J lin. long, 
pale (except for the hairs) ; callus slender, acute, J lin. long, black 
on the back, shortly bearded. Glumes equal ; lower thinly charta- 
ceous, minutely truncate, dorsally flat, fulvously hairy all over, 
margins narrowly involute, keels obscure, nerves 7-9 ; upper glume 
membranous, obtuse, sometimes mucronulate, 3-nerved, hairy 
upwards, reversedly ciliate. Lower floret reduced to a linear- 
oblong obtuse hyaline reversedly ciliate valve. Upper floret ^ : 
valve stipitiform, acutely 2-toothed, awn 14-lf in. long, column 
brown, fulvously pubescent . Anthers 1 lin. long. Pedicelled spikelets 
linear-lanceolate, 2 lin. long, resembling the sessile in colour and 
t omentum ; glumes subequal, very acute ; lower closely 11 -nerved ; 
upper 3-nerved ; valves decreasingly shorter, ciliate, lower oblong, 
upper linear. — Andropogon poecilotrichus , Hack, in Bolet. Soc. Brot.

The only specimen seen is the type in the Coimbra Herbarium. It is rather 
imperfect, the middle portion of the culm being missing, and the “ panicle ” 
described by Hackel and again here is very likely only a compound ray of a 
much longer panicle. 
8. H. vulpina, Stapf. Perennial, up to over 5 ft. high, densely 
csespitose ( Gossweiier ) with extravaginal innovations. Culms erect, 
stout (up to 21 lin. in diara.), terete, solid, glabrous and smooth, 
simple and 3-5- noded below the panicle. Leaf-sheaths very firm, 
terete, hairy particularly upwards, the lowest more or less woolly 
at the base or perfectly glabrous, the basal often up to 9 in. 
long ; ligules scarious, truncate, about 1 lin. long, mostly with hairs 
from behind ; blades narrowly linear from an equally wide or more 
or less attenuated base ? long-tapering to a fine point, rigid, over
