y 8. C. Afronardus, Staff. Perennial, tall, compactly csespitose, 
the intravaginal innovations and culm-bases coated with long tough 
slender sheaths or their bases. Culms erect, terete, stout, up to 
2J lin. thick, 3-4-noded and simple below the panicle, glabrous, 
smooth ; lower internodes over 1 ft. long. Leaf-sheaths terete, 
firm, prominently striate, the basal over 6 in. long, narrow upwards, 
widened and the outer of them hirsute towards the base, otherwise 
glabrous and quite smooth ; ligulesscarious,of the innovations up to 
over 6 lin. long, of the culm-leaves much shorter (rarely over 2 lin.), 
rounded or truncate, ciliolate ; blades narrow from a long-attenuated 
base or almost reduced there to the stout midrib and much narrower 
than the mouth of the sheath, tapering upwards to a fine point, 
the basal up to over (probably 2) ft. by 1|— 2 lin., the cauline also 
very long (over 1 ft.), up to 3 lin. wide, very firm, green, rigid or 
flexuous upwards, the lower quite glabrous, smooth except on the 
scabrid margins, the uppermost rough all over, midrib semiterete 
downwards, whitish above, lateral nerves moderately prominent on 
both sides. Spatheate panicle decompound, oblong to linear, usually 
more or less secund, to over 1 ft. long, mostly interrupted below, 
internodes about 4-5, lowest 6-10 in. long, rarely much shorter, 
upper rapidly decreasing in length ; lowest subtending leaves with 
herbaceous sheaths 2-4 in. long and short normal blades, upper 
spathaceous ; lower and intermediate primary branches, or all but 
the uppermost, forming mixed tiers, the longest of their rays often 
considerably exceeding the supporting sheath, up to 4- and even 5- 
noded, and bearing secondary and sometimes tertiary tiers ; ultimate 
tiers few- to 10-rayed, corymboid ; rays finely filiform, of the peri- 
pheral tiers 6-4 lin. long, glabrous or sparingly hairy towards the 
tips ; spathes lanceolate, acute or subulate-acuminate, J-l in. long, 
subherbaceous with scarious reddish margins. Spatheoles narrow, 
linear-lanceolate to lanceolate, acute or subacute, scarious, pale 
reddish to brown, 6-8 lin. long ; peduncles filiform, 2-4 lin. long, 
glabrous. Racemes 2-nate, ultimately more or less divaricate and
