upper glume shorter to much shorter, acute, 3-nerved, ciliate ; 
valve of lower floret if fully developed linear-oblong, up to 4 lin. long, 
sub-3-nerved, reversedly ciliate, of the upper very much shorter 
or both greatly reduced ; anthers 2J lin. long. Spikelets of the 
homogamous pairs similar to the pedicelled. but muticous, from 5-6 J

56. H. notolasia, Slapf. Annual, 8-10 ft. high. Culms robust, 
up to 2 ]in. in diam., simple and about 4-noded below the panicle, 
terete, glabrous. Leaf-sheaths terete, tight, at length slipping ofl 
the culms altogether (lowest), or upwards only and inrolled from 
the margins, smooth, glabrous ; ligules scarious, short, truncate, 
ciliolate, blades linear from an equally broad or gradually narrowed 
base, tapering to a long point, up to over 1 ft. by 3 lin., pale green, 
flaccid, more or less rough on both sides and scabrid along the 
margins, slender or somewhat stout downwards, whitish below ; 
primary lateral nerves 3-4 on each side, slightly raised. Spatheate 
panicle narrow, very lax, up to 2 ft. (or more ?) long, of over 4 
distant mixed or upwards simple tiers ; lower tiers few- to 6-rayed 
with the compound rays up to over 6 in. long and 2-3-noded ; simple 
rays very slender, filiform, 1 to over 2 in. long, frequently strongly 
arched or recurved ; lower spathes resembling the preceding leaves 
with long blades. Spatheoles narrowly lanceolate, long and finely 
acuminate, 2J-3§ in. long, up to 1J lin. wide, scarious, pale tinged 
with purple, finally inrolled from the margins but never tightly ; 
peduncles filiform, up to 1 in. long, flexuous or recurved and exserted 
from the spatheole, glabrous. Racemes nodding, subcontiguous or 
slightly spreading, up to 1 in. long, contracted, greenish, 2-3-awned 
per pair; raceme-bases rather stout, up to 1 lin. long, dorsallv 
compressed, densely pubescent in the fork, exappendiculate ; joints 
if any, slender, filiform, with obliquely truncate tips shortly silky - 
ciliate, 1 lin. long ; pedicels similar, up to 2 lin. long. Homogamous 
pairs of spikelets 1 at the base of the upper, 2 at that of the lower 
raceme, the latter forming a persistent imperfect involucre. Fertile 
spikelets oblong, 4 lin. long including the callus, pale green, tomentose ; 
callus slender, acute, 1 lin. long, finely grooved on the back, shortly 
silvery bearded. Glumes equal, firmly chartaceous, minutely trun- 
cate ; lower rounded on the back, shortly villous almost all over, 
faintly 9-nerved, very finely grooved along the middle nerve at the 
base ; upper glume 3-nerved, ciliolate on the rounded keel, and 
reversedly so on the margins. Lower floret reduced to a linear- 
oblong obtuse ciliate 2-nerved hyaline valve. Upper floret ^ : 
valve stipitiform, minutely 2-toothed ; awn 2J to over 3 in. long, 
column brown, subplumose, hairs white, J-f lin. long, bristle pale ; 
valvule 0. Anthers 1J lin. long. Pedicelled spikelets or neuter,
