Afric., E. Asia, 
Annual, nearly glabrous. Stems 1-6 in., tufted. Leaves often as long as stem, 
capillary. Umbel often 1-3 in. diam. ; bracts several, often overtopping umbel. 
elets X in, diam., subglobose, dense with aristate glumes. Glumes elliptic, pale, 
nerve: green long exeurrent into a curved tail. Stamen 1 or 2; anthers small, 
oblong, not crested. Style slender, glabrous, branches longer than nut; style-base 
‘lightly bulbous, persistent or deciduous. Young pistil frequently ornamented by 
clavate glands, which usually disappear in fruit, but in Wight, n. 1865 (described in 
. Pl. iii. 1049), are developed into ovoid processes nearly as wide as nut. Nut 
nearly as long as glume (omitting its arísta), usually smooth pale brown, minutely 
Dsversely wavy-lined, but sometimes papillose scabrous by reason of the persistent 
glands.— Perhaps a distinct genus, for it is not closely allied to any other species. 
authors have placed it in Scirpus, Sect. Micrantht, to which it has little re- 
semblance, except in tbe aristate squarrose glumes ; the nut and style are wholly 
different, Bentham has placed it in Fimbristylis with which the inflorescence 
glumes and even nut fairly agree, but the style does not; it is often deciduous, and 
lie metimes leaves a minute button on the apex of nut, much as in Bulbo- 
tH Style-base with many long pendent hairs.

easily deciduous with the (then conspicuous) trichomes. Nut as long as 4 glume,
