Tropical Africa an?l India, common, cxtendin*,' thence to Amurlund, but not 
yet received from the Malayan Archipelago. 
In thi.s species the very young ovary is often (not ahvays) ornafnentcd witli 
prominent clavate glands, as shown by Dcsveaux, which often dibappuar in the 
ripe fruit; a cliaracter considered by Dcaccaux to be of generic value. 
8. Fimbristylis dichotoma Vahl, Enum. 2 (1806) 287. 
Spikelets numerous, oblong, somewhat angular by reason of the keeled 
glumes; nut obovoid, transversely trabeculate between the longitudinal

Throughout the warmer parts of the Old World; an abundant species. 
This species is only distinguishable from Fimbristylis diphylla Valil, by 
characters of trifling importance; examples marked by eminent* cyperologists 
F. dichotoma Vahl, are, not very rarely, marked by other eminent cyperologists 
F. diphylla.. 
9. Fimbristylis diphylla Vahl ! Enum. 2 (1806) 289. 
J 
Spikelets oblong, terete, the glumes less keeled than in F. dichotoma 
V^ahl, the nuts indistinguishable from those of the latter.

In all warm countries; perhaps the most widespread and abundant of 
Cypet^acece. 
The species is here taken in rather a narrow sense, and has about 150 
published names. If the species is limited as in Kunth it would have about
