19. D. Lecardii^ Stapf. Annual (?). Culms (base unknown) 
over 2j ft. high, erect, slender, simple or with a branch from one 
of the lower nodes, apparently few-noded, the uppermost internode 
very long and long-exserted, glabrous, rough towards the inflorescence. 
Leaf-sheaths somewhat loose, finely striate, glabrous except at the 
loosely bearded nodes, or sparingly and finely hairy ; ligules reduced 
to a membranous ciliolate rim with some long hairs from the back ; 
blades linear from an equally broad base, 6-9 in. by. l|-2 lin., flat, 
flaccid, rough, particularly above and upwards, glabrous or with a few 
very fine hairs near the base, midrib very slender, lateral nerves 
somewhat hne, close. Racemes 2-4, sessile, compound, at least in 
the lower part, subdigitate or with a slender rough common axis 
(1-14 lin. long), slender, erect or obliquely erect, straight, rather 
loose, 4-6 in. long ; rhachis slender, triquetrous, §-J lin. wide, 
straight or slightly wavy, finely puberulous, lateral angles marginate, 
scabrid, internodes 1^-2 lin. long ; pedicels in the upper part 3-4- 
nate, lower down fascicled with short sparingly spiculiferous branch- 
lets, 3-6 (rarely up to 15) lin. long, very slender, angular, scabrid, 
often with a few very short hairs, the longest usually 1-2 lin. long. 
Spikelets oblong to ovate-oblong, acute, about 1 lin. long, pale or 
whitish-green with silky sides when young, at length greyisli-gieen 
with a rufous fringe. Lower glume indicated by a very minute hyaline 
irregular rim at the base of the lower floret, or 0 ; upper lanceolate 
or narrowly oblong, acute or subacute, about ~ lin. long, very thin, 
3-nerved, densely and at length spreadingiy hairy all over, hairs 
slightly curved or straight, with short very acute points. Lower 
floret corresponding in outline and size to the spikelet : valve 
firmly membranous, slightly depressed and glabrous between the 
innermost side-nerves, 7-nerved, middle-nerve very slender, smooth, 
side-nerves approximate on the slightly bulging and rounded-off 
sides, with dense lines of hairs between the inner side-nerves (of each 
half) and along the margin, hairs as in the upper glume, if not longer 
and more rigid, with usually a few additional large almost bristle- 
like hairs from the inner line, forming at length a conspicuous rufous
