Leaves narrow. Umbels sometimes reduced to a single head 
or even spikelet, usually simple or compound up to the third 
degree ; rays unequal, one or two of the central rays occasionally 
suppressed so that the point of forking is occupied by a sessile 
cluster of spikelets. Bracts usually short, often erect. Spikelets 
few or many, in F. monostachya and frequently in F. schcenoides 
there is only one, in pairs or in clusters. Glumes many, ovate, 
imbricate all round the axis, falling off successively from below ; 
the lowest 1 or 2 empty, the others containing a 2-sexual flower, 
but the uppermost soon withering. Stamens 3, sometimes 2 or 1. 
Styl# long, frequently hairy, 2- or 3-branched, swollen towards 
the base but abruptly constricted just above the nut, at which 
point it ultimately falls off. Nut obtuse, narrowed towards the base.

1. Fimbristylis schcenoides, Vahl ; FI. Br. Lid. vi. 634. 
Glabrous ; rhizome none or very short ; stems tufted, 4-12 in., 
slender, grooved, base often thickened. Leaves about three quarters 
the length of the stem. Spikelets § in., ovoid, rusty-brown, 1-3 in 
a single head. Glumes obtuse. Style hairy nearly to the base, 
2-branched. Nut one third to half the length of the glume, 
flattened, smooth. 
Throughout India, ascending to 6500 ft. — China, Australia. 
2. Fimbristylis squarrosa, Vahl ; FI. Br. Lid. vi. 635. Annual ; 
stems tufted, 2-8 in., slender, grooved. Leaves half to three quar- 
ters the length of the stem, usually pubescent. Umbels compound, 
often 2-4 in. diam. Spikelets many, in., narrowly oblong, 
red-brown. Mid-rib of glumes running out at the top in a tail-like 
point nearly as long as the glume itself. Style minutely hairy, 
2-branched, fringed at the base with 10-18 white hairs. Nut one 
third the length of the glume, flattened, smooth. 
Common in rice-fields throughout India, ascending to 3000 ft. — All warm 
regions.
