prominent in the tip, keels fine, minutely and rigidly ciliolate ;

long. Pedicelled spikelets linear-lanceolate, very acute, up to 
7 lin. long, reddish-brown, purplish, glabrous ; upper glume with or 
without a terminal bristle, up to 6 lin. long, very closely and finely

40. H. Wei wits chii^ Stapf Annual (?), tall, up to 9 ft. high 
(Pobeguin). Base unknown. Culms moderately stout, with dense 
yellowish beards 1J lin. long from just below the insertion of the 
leaf-sheath, otherwise perfectly glabrous and smooth. Leaves 
quite glabrous, only those of the panicle known ; sheaths firm, 
terete, tight, strongly striate upwards, glabrous, smooth, produced 
at the mouth into lanceolate auricles, up to 3 lin. long ; ligules 
scarious, otherwise glabrous, as long as and adnate to the auricles 
of the sheath ; blades linear from a slightly narrowed base, tapering 
to a fine point, up to 1 J ft. by 5 lin., dull green, slightly glaucescent, 
quite glabrous, almost smooth except upwards and along the scabrid 
margins, primary lateral nerves about 5 on each side, very slender. 
Spatheate panicle large, loose, leafy, up to over 2 ft. long, bearded 
at all the nodes, of about 7-8 mostly mixed distant or upwards 
approximate 2-5- (rarely 6-) rayed tiers ; lowest and strongest 
compound rays up to over 9 in. long and up to 5-noded, bearing 
secondary tiers ; ultimate rays slender, filiform, j-1 J in. long ; lower 
subtending leaves like the preceding, the intermediate with more or 
less reduced blades, shorter than the panicle, the uppermost spathe- 
oloid. Spatheoles cymbiform, lanceolate, narrow, tapering to a fine 
point, about 1J in. (rarely 2 in.) by 1J-1J lin., scarious, reddish or 
brownish-purple, glabrous, at length inrolled from the margins and 
very narrow ; peduncles very slender, filiform, slightly arched or 
recurved upwards with a beard of fine stiff tubercle-based yellow 
hairs from the curvature, laterally exserted, at length exceeded 
by the spatheole by a few to 6 lin., rarely equalling it. Racemes 
subcontiguous, nodding, at length epinastically deflexed, rather 
loose, 6-8 lin. long, brownish, 2-4-awned per pair ; bases subequal, 
not much over J lin. long, dorsally compressed, pubescent in the 
fork and bearded upwards, beards like those of the peduncles, 
the upper produced into a scarious oblong denticulate purplish
