Guin. PI. 52. Perennial. Culms slender, glabrous, smooth, 4-6-noded, 
up to 3 ft. high. Leaf-sheaths firm, terete, glabrous, rarely with a 
small beard at the mouth, smooth, strongly striate, produced at the 
mouth into lanceolate auricles, up to 1J lin. long ; ligules scarious, 
truncate, glabrous, adnate to the auricles of the sheath ; blades 
very narrow, linear, long-tapering to a subacute point, usually 
much narrower at the base, up to 1 ft. long and 1J lin. wide, con- 
volute or with recurved margins, flat, glabrous or hirsute above the 
ligule, smooth except near the tips and along the margins, or rough 
all over above, midrib slender, raised below, primary lateral nerves 
about 2 on each side. Inflorescence consisting of a terminal raceme- 
pair, augmented by 2 or 3 very distant 2-rayed mixed or simple 
tiers ; spathes resembling the preceding leaves with more or less 
well developed blades ; rays slender, filiform, very unequal, erect, 
strict, the primary up to over -J ft. long. Spatheoles subscarious, 
acute, glabrous, 3-4 in. long, with much reduced subulate or short 
bristle-like blades, finally more or less tightly inrolled ; peduncle 
often of the same length as the rays, long-exserted. Racemes 2-nate, 
erect, subflexuous, 1J-2J in. long, one sessile, the other with a 
short base, sparingly hairy ; joints oblong-cuneate from a slender 
base, stout upwards, much rounded on the back and deeply concave 
on the face, over 1J lin. long, ciliate with a tuft of short hairs near 
the base of the outer angle and shortly ciliate along the inner up to 
the middle, otherwise glabrous and smooth, tips slightly emarginate, 
hardly hollowed out ; pedicels very similar, slightly shorter. Sessile 
spikelets all (?) heterogamous, linear in front view, including the 
minute and shortly bearded callus 2 \ lin. long, pale. Glumes subequal ; 
lower thinly chartaceous along the middle, firm towards the keels, 
minutely 2-dentate, deeply and narrowly grooved between the keels, 
glabrous, smooth except for the upwards scaberulous keels, inflexed 
margins rather narrow, 7-nerved, 1 nerve on each side of the groove 
and 2 close to each keel ; upper glume boat-shaped, rounded on 
the back below, keeled above, produced into a short curved mucro, 
membranous, 3-nerved, ciliolate, scabrid on the keel above the
