side. Sessile spikelet broadly ovate-lanceolate, acuminate, in- 
cluding the small stipitate hairy callus and excluding the bristles 
3-3 J lin. long. Glumes unequal ; lower chartaceous, produced 
into 2 straight bristles up to 1J lin. long, penicillate-ciliate from the 
base upwards, with about 12 tufts of hairs, each tuft carried on a 
stout laterally projecting process, densely hairy on the back, intra- 
carinal nerves about 6, faint ; upper glume membranous, lanceo- 
late, acute, sometimes shortly aristulate, 2-2J lin. long, pubescent, 
ciliolate, 3-nerved. Lower floret as long as the upper glume : valve 
lanceolate-oblong, subacute, hyaline, ciliolate, 2-nerved. Upper 
floret 1J lin. long : valve linear-oblong, acute, 3-nerved, glabrous ; 
valvule minute, nerveless. Anthers 1J-2 lin. long. Stigmas of the 
same length. Pedicelled spikelet lanceolate, 2J-3 lin. long. Glumes 
equal ; both or only one of them aristulate, with the awn up to 
2J in. long ; lower keeled and ciliate on one side only, cilia short 
and not penicillate, nerves about 4-5, apart from the keel ; upper 
glume boat-shaped, obliquely lanceolate in profile, keeled upwards, 
with 1-2 nerves on each side. Florets as in the sessile spikelet or 
slightly smaller, the upper <£ . — Durand & Schinz, Consp. FI. Afr.

2. E. elegans, Kunth, Rev. Gram. 161 and 361, t. 94. Annual, 
growing gregariously. Culms erect, up to 2 ft. high, simple or with 
1 or 2 flowering branches from the upper nodes, slender, terete, 
bearded close to the nodes, otherwise glabrous, smooth, about 3- 
noded, internodes mostly long-exserted. Leaf-sheaths terete, tight, 
^ glabrous or frequently bearded, or the lower more or less hirsute ; 
ligules very short, membranous, densely ciliate ; blades linear, 
acute, 2-3 (rarely up to 5) in. long, up to 1 lin. broad, flat, flaccid, 
glabrous or sparingly hairy to hirsute towards the base, smooth 
excepting along the margins, especially upwards, 1 lateral nerve on 
each side rather prominent below. Racemes 1J to over 2 in. long, 
the terminal on long exserted slender peduncles, straight or sub- 
falcate, straw-coloured, sometimes tinged with purple. Rhachis 
very fragile ; joints linear, stout, subtriquetrous, about 1 lin. long, 
disarticulating very obliquely, with a large rounded scarious ciliate 
appendage, ciliate on the outer angle, the upper cilia 1 lin. long, 
minutely ciliolate along the other angles ; pedicels similar, but 
more slender and without an appendage. Sessile spikelet oblong- 
lanceolate, including the stipitate shortly bearded callus 2J lin. 
long, excluding the bristles. Glumes unequal ; lower thinly charta- 
ceous, produced into 2 straight bristles, up to over 1 lin. long, peni- 
cillate-ciliate from the base upwards, with about 10-12 tufts of 
hairs, each tuft carried on a stout laterally projecting process,
