Luzon, Manila, (1855 Wichura) ; Laguna, (5105 Merrill). 
Tropical Africa and India, common, extending thence to Amurland, but not 
yet received from the Malayan Archipelago. 
In this species the very young ovary is often (not always) ornamented with 
prominent clavate glands, as shown by Desveaux, which often disappear in the 
ripe fruit; a character considered by Desveaux 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 
ribs.

Philippines, . {Llanos) . Luzon, Manila, (1342 Lolier) . 
Throughout the warmer parts of the Old World; an abundant species. 
This species is only distinguishable . from Fimbristylis diphylla Vahl, by 
characters of trifling importance ; examples marked by eminent cyperologists 
F. dichotoma Yahl, are, not very rarely, marked by other eminent cyperologists 
F. diphylla. 
9. Fimbristylis diphylla Yahl ! Enum. 2 (1806) 289. 
Spikelets oblong, terete, the glumes less keeled than in F. dichotoma 
Yahl, the nuts indistinguishable from those of the latter.

Philippines, ( Meyen ). Luzon, (1854 Wichura) ; (558 Cuming)-, (763, 764, 
765 Lolier) ; (1141, 4252, 4632 Merrill) ; (70 McGregor) ; (6300, 6470 Elmer) ; 
(6135 Leiberg) . Mindanao (2001 Wichura) ; (545 Copeland)-, (Clemens). 
In all warm countries; perhaps the most widespread and abundant of 
Cyperacece. 
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
