6. TJ. echinolaenoides, Stapf. Annual, in small tufts, up to 1J ft. 
high. Culms geniculately ascending or suberect, slender, few-noded 
(the uppermost internode by far the longest and long-exserted), 
simple or with a short branch from the lowest node, glabrous or 
nearly so. Leaf-sheaths somewhat loose, soon slipping off the stem, 
subherbaceous, striate, densely ciliate, otherwise glabrous or sparingly 
hairy ; ligules reduced to a densely ciliate rim ; blades linear from an 
equally wide base, tapering to an acute point, up to 3 in. by 3 lin., 
flat, green, loosely hairy, often sparingly so, midrib and lateral 
primary nerves (3-4 on each side) very slender. Inflorescence long- 
peduncled, secund, of 2-3 oblique stiff subsessile racemes ; common 
axis J-l in. long, semiterete or slightly flattened upwards, densely 
pubescent to tomentellous along the angles, ending with a barren 
rigid point. Racemes dense, 3-4-seriate, simple, f to over 1^ lin. 
long, solitary ; rhachis triquetrous, flat on the back, puberulous on 
the face, angles scabrid, internodes about 1 lin. long ; pedicels 2-nate, 
one rather slender, J lin. long, puberulous with some fine longer 
yellowish bristles, the other very much shorter to obsolete. Spikelets 
on the whole crowded, but the superposed distinctly distant, ovate- 
lanceolate, long-acuminate, up to over 2J lin. long, dull greenish, 
greyish-pubescent, fulvously setose. Glumes dissimilar ; the lower 
broad-ovate to ovate-lanceolate, acuminate, thin, f-1 lin. long, 
3- or sub-5-nerved, very minutely pubescent, often with 1-3 tubercle- 
based bristles ; upper corresponding in shape and outline to the 
spikelet, membranous, 5-7-nerved, finely pubescent with a row of 
bristles on each side. Lower floret : valve very similar also as 
to vestiture to the upper glume, but slightly shorter ; valvule oblong, 
acuminate, minutely truncate, about J lin. long, with marginate 
keels ; anthers 1 lin. long. Upper floret elliptic-oblong, 1J-2 lin. 
long, the obtuse tip very minutely puberulous, whitish, delicately 
granular ; mucro f lin. long, barbellate.

7. U. Helopus Annual, tufted, 1-2 ft. high. Culms 
erect or geniculately ascending from a short sometimes rooting 
base, usually rather slender, frequently sparingly branched from 
the lower nodes, 4-10-noded, intermediate internodes shortly 
exserted, like the uppermost (peduncle) very sparingly pubescent or
