13. A. eucomus, Nees, FI. Afr. Austr. 104. Perennial, densely 
tnfted, with, numerous short innovation-shoots. Culms 1-3 ft. long, 
compressed below, glabrous, 4-6- or more-noded, simple to or beyond 
the middle. Leaf-sheaths glabrous or hairy near the mouth, rarely 
lower down, firm, those of the innovations and at the base of the culms 
compressed and keeled, the remainder shorter than the internodes, 
terete, distant, the uppermost subtumid ; ligules membranous, very 
short, truncate, ciliolate ; blades linear, acute, folded, from 3 in. 
to 1 ft. long, 1-1| lin. wide (when unfolded), glabrous or sparingly 
hairy, pale green, smooth or slightly scaberulous on the margin, 
midrib slender, prominent below, lateral nerves 4-5 on each side, very 
fine. Inflorescence a subfastigiate or elongated and interrupted 
spatheate panicle ; tiers few, rarely more than 4, distant, the lowest 
sometimes mixed ; spathes linear-lanceolate, acuminate or acute, 
usually without a blade, glabrous, pale-green or tinged with purple 
or red, at length tightly inrolled ; rays filiform, strict, glabrous, 
rarely over 3 in. long. Spatheoles similar to the spathes, up to 3 in. 
long ; peduncles at length often long-exserted, often slightly arching. 
Racemes 2-5, subdigitate, very rarely solitary, very slender, 1-2 in. 
long, plumose, often nodding ; joints finely filiform, shorter than the 
spikelets, silky with soft long (about 5 lin.) hairs ; pedicels similar, 
more or less exceeding the spikelets, quite barren. Sessile spikelet 
narrowly lanceolate-oblong, 1 to over 1J- lin. long, often purplish, 
glabrous ; callus minute, long-bearded. Glumes equal, membranous, 
acute, the lower nerveless between the scabrid keels, the upper 
1-nerved. Lower floret almost as long as the glumes, reduced to 
a nerveless ciliate valve. Upper floret : valve lanceolate-oblong, 
very narrow, ciliolate, 2-fid to one-third ; lobes finely subulate ; 
awn a fine bristle, 6-9 lin. long ; valvule very minute. Anthers 
i lin. long. Grain linear-lanceolate in outline, subcylindric, purplish, 
over J lin. long. — Steud. Syn. PI. Glum. i. 390 ; Oliv. in Trans. Linn.
