m 
radicalibus, tenuibus, subrigidis, 4 ad 8 cm longis, circiter 1 mm 
latis; inflorescentiis longe et tenuiter pedunculatis, umbellatis, 
simplicibus vel compositis more Fimbristylis diphyllae; spiculis

that of Fimbristylis diphylla and allied species, rather dense, or 
lax, the spikelets fascicled or solitary, some sessile, others pedi- 
celled, 5 to 20 in each inflorescence, the inflorescence subtended 
by 1 to several narrow, rigid, 0,5 to 2 cm long, leaf -like bracts 
which are inflated below and pubescent; rays few, up to 5 cm 
in length, usually much shorter. Spikelets brown, oblong, com- 
pressed, 5 to 8 mm long. Glumes all distichous, or the lower
