Annual, nearly glabrona. Stems 1-6 in., tufted. Leaves often as long as stem, 

 capillary. Umbel often 1-3 in. diam.; bracts several, often overtopping umbel. 

 Spihelets i in. diam., subglobote, dense with aristate glumes. Q-lumes elliptic, pale, 

 nerve green long excnrrent into a curved tail. Stamen. 1 or 2 ; anthers small, 

 oblong, not crested. Style slender, glabrous, branches longer than nut ; style-base 

 slightly bulbous, persistent or deciduous. Young pistil frequently ornamented by 

 clavate glands, which usually disappear in fruit, but in Wight, n. 1865 (described in 

 Gen, PI. iii. 1049), are developed into ovoid processes nearly as wide as nut. Nut 

 nearly as long as glume (omitting its aris&), usually smooth pale brown, minutely 

 transversely 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. 

 Most authors have placed it in Scirpus, Sect. Micranthi, to which it has little re- 

 semblance, except in the aristate squarrose glumes ; the nut and style are wholly 

 different. Bentham has placed it iu Fimbristylis with which the inflorescence 

 glumes and even nut fairly agree, but the style does not ; it is often deciduous, and 

 then sometimes leaves a minute button on the apex of nut, much as in Bulbo- 

 stylis.

Annual; all parts pubescent, puberulons or glabrous. Stems 2-8 in., striate, 

 ieaws as long as i-J stem. Umbels often 2-4 in. in diam., with many spikelets; 

 bracts usually short, sometimes as long as umbel. Spihelets i—i by -jij in. Glumes 

 fuscovis, keel 3-5-nerved, excurrent into a curved tail. Stamens often 2. Style 

 small, hairy below bifurcation ; from the margin of style-base hang 10-18 uni- 

 cellular slender linear trichomes, as long as ^-| nut, closely adpressed to it; style- 

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

 never conspicuously striate longitudinally. 



ttt Nut obovoid, conspicuously longitudinally striate, trabeculate (by 

 reason of the transverse short-oblong celh between the striations). 



14. F. dichotoma, Vahl Enum. ii. 287 ; umbel compound or decom- 

 pound, spikelets many solitary oblong angular, glumes ovate acute gla- 

 brous, style 2-fid, nut 5-9-striated on each face straw-colrd. or rarely 

 discolrd. black-brown. . Nees in Wight Contrib. 101; Boeck. in lAnnsea,
