Annual, pubescent or puberulous. Stems 2-10 in., tufted. Leaves often as long 

 as stem, narrow.. Umbel often 2-4 in. diam., sometimes with 9-5 spikelets only ; 

 bracts often as long as umbel. Spikelets i by ^ in., somewhat angular from the 

 acute keels to glumes. Glumes boat-shaped, ferruginous, keel green 1-3 -nerved, 

 lowest empty more or less bract-like often pubescent. Stamens 2-1 (or 3 fide

 glume, biconvex ; outermost cells, shortly transversely oblong, conspicuous, vertically 

 superimposed in 5-9 rows on each face of nut. Closely allied to F. diphylla, in 

 which the spikelets are terete, the glumes being much less keeled than in F. dicho-
