228 XXVIII. GRAMINER. [Triraphis 
sheaths and leaves reddish. Leaf-sheaths 1 to 14 in. long, or the 
lowermost shorter, the ascending or suberect blades except the 
shorter ones at the base of the culm, 14 to 32 in. long from 
scarcely 1 to 2 lines broad. Panicle half the height of the plant, 
more or less oblong tapering at the base ; spikelets reaching } in., 
but generally shorter, with 8 to 9 or fewer flowers; barren glumes 
about 14 line long, or the lower sometimes perceptibly shorter, 
12 line; flowering glumes membranous with 3 strong nerves, the 
lowest 13 to 12 line long not including the awns. 
Near 7. Elliotii Rendle, but distinguished by its larger laxer 
panicle with smaller spikelets and glumes, and pilose habit.

1. E. benguellensis Rendle sp. nov. 
Apparently perennial and cespitose, culms ascending, ultimately 
erect, geniculate, branching at the base; nodes dark, glabrous , 
cauline internodes 3 to 4, glabrous, terete, except the lowest 
exceeding the short loose membranous sheaths which are sparsely 
pilose at the mouth only; ligule a short row of hairs; blades 
rigidulous, subpatent, linear-tapering, acute, flat or incurved, 
glabrous except for a few hairs on the upper face at the base; 
inflorescence of a few spikelets sessile on the main rhachis, which 
in one case bears a lateral branch; spikelets ovate, densely many- 
flowered, distichous, compressed ; glumes coriaceous, the lower 4 
barren, 3- to 7-nerved, ovate-lanceolate to broadly ovate, increas- 
ing in size and strength upwards, strongly cuspidate, keels scab- 
ridulous, margin ciliate, especially near the base; fertile glumes 
broadly ovate, with a strong broad-margined ventricose base, and a 
subtruncate strongly cuspidate apex, strongly 7-nerved, 9-nerved 
below the apex, margins hyaline and ciliate especially near the 
base; pale hyaline, large, flat, narrow-lanceolate, blunt, the 
broad edges inflexed at the well-marked ciliate keels, a little 
shorter than the glume; anthers long, linear; styles long, 
plumose, projecting from between the cusps of the glumes. 
Plants small, culms reaching 1 ft. high and 2 line in diameter ; 
leaf-sheaths 3 to barely 1 in. long, blades scarcely exceeding 2 in. 
long by 2 lines in width at the base, jointed to and ultimately 
separating from the sheath. Inflorescence 1} in. long by scarcely 
? in, broad; spikelets about 3 in. long by + broad, the majority 
contorted above the middle (probably from the attack of an insect).
