1 / 1. D. Seretii,, Staff. Annual, about 3 (or more ?) ft. high. Culms 
in scanty fascicles, erect, glabrous, smooth, intermediate inter 
nodes up to over 1 ft. long, long-exserted. Leaf-sheaths terete, 
smooth and glabrous, except on the ciliate margins, or the lowest (?) 
villous at the base ; ligules scarious, rounded, ciliolate, glabrous, up 
to 2 lin. long ; blades linear from a slightly attenuated or equally 
wide base, long-tapering to an acute point, up to 1J ft. (or more ?) 
by 3-6 lin., green, glabrous, or sparingly hirsute, slightly rough on 
the upper side, smooth below, margins spinulously scabrid. In- 
florescence of 1 terminal about 7 -rayed umbel] if or m tier or two 3-4 
rayed tiers, the lowest about 14 in. long ; subtending leaves with 
more or less spathaceous sheaths and reduced blades, often over- 
topping the inflorescence. Spatheoles permanently cymbiform, 
lanceolate, long and acutely or subacutely acuminate, 2-3 in. long, 
3J lin. wide in profile, brownish-green, glabrous, smooth except for 
the scabrid keel of the acumen ; peduncle filiform, with a discoid 
tip, up to 7 lin. long, glabrous or with some hairs upwards, perma- 
nently enclosed in the spatheole. Racemes laterally incompletely 
exserted from the spathe, permanently contiguous, about 10-12 lin. 
long ; bases very short, with an annular thickening at the nodes, 
sparingly hairy upwards, intermediate disarticulation-face oblique, 
wide, terminal disarticulation very oblique, tip auriculiform ; pedicels 
of the trio adnate at the base to the side of the lower glume of the 
fertile spikelet, free part 3J lin. long, very densely and shortly silky - 
ciliate. Homogamous pairs of spikelets 2. Fertile spikelet linear- 
oblong, 2-mucronulate, including the callus 9-11 lin. long, straw- 
coloured ; callus 2J-3-4 lin. long, very pungent, very densely bearded, 
hairs white, silky, the uppermost over 1 lin. long. Glumes equal, 
coriaceous ; lower with a fine longitudinal groove at the base and 
there densely villous, loosely and shortly hairy upwards, at least on 
the sides and below the acumen, about 1 3-nerved, nerves very 
obscure, acumen § lin. long, turning brown, mucros and keels rather 
firm ; upper glume subcoriaceous, deltoid-truncate, very minutely 
pubescent upwards, middle nerve prominent towards the tip, margins 
reversedly ciliolate. Low x er floret : valve linear-oblong, obtuse, 
about 5 lin. long. Upper floret ^ : valve 1 lin. long, glabrous, awn 
up to 5 in. long, golden-fulvous, appressedly silky-pubescent, 
slightly bent at the middle and again somewhat below it ; valvule 
linear-oblong, about 1J lin. long, ciliate at the tip. Anthers 2|- lin. 
long. Pedicelled spikelets (the trio) linear-lanceolate, 6-8 lin. long, 
glabrous ; lower glume subcoriaceous, passing into a mucro or very 
short bristle, obscurely many-nerved ; upper shorter, very acute, 
3-nerved, reversedly ciliate ; lower valve oblong-obtuse, up to 
4 lin. long, 3-nerved, upper very minute, obovate, ciliate ; anthers 
4 lin. long. Homogamous spikelets linear-lanceolate, up to 10 lin.
