Species of Fimbristylis, VuJd, R, Broinu 



Species of Scirpus, Linn. 



This genus includes all the species of Fimbristylis of Vahl 

 which have a triangular nut and a 3-cleft style. Some of them 

 are difficult to distinguish from Isolepis, except by a careful 

 examination of the style, which in Trichelostylis is swollen at 

 the base, and separates entirely from the nut; while in Isolepis 

 the style is nearly equal, or only furnished with an extremely 

 minute tubercle which remains attached to the nut after the 

 separation of the style. 



Trichelostylis mucronulatus. 



Culm compressed, somewhat ancipital; umbel decompound, 

 divaricate ; involucre two-leaved ; spikes oblong-lanceolate, 

 mostly pedicellate, acute ; scales ovate-lanceolate, about four- 

 ranked, miicronate, the point a little spreading ; stamens 2 ; 

 nut obtusely triangular, (white) very obtuse, tuberculate.
