TRIANDRIA. MONOGYNIA, ' Si 
spikelets constantly suhiebeidic.Gnla 2- 
valved, 1-flowered, the valves unequal. Corol- 
la 2-valved, larger than the calix. Seed tri- 
quetrous. (Stamina 1, 2, and 3; stigmas 2, 
and 3.) - 
Flowers capitate, or umbelisteeapteate, terminal; in= 
volucrum of the head or umbell 3, 4, or many-leaved; 
culm often triangular. (According to the observations 
of Mr. Elliott, in his Sketches of the Botany of South Ca- 
rolina and Georgia, the K. pumila of Micn. has no calix, 
and the K. maculata of M. a calix of only 1 leaf.) _

the United States, the genus Kyllingia is confined 2 the 
tropical regions of India and America,

Culm triquetrous, sheathed at the base with chant squa- 
mose lanceolate leaves; flowers in a terminal involu- 
crate capitulum, the involucrum consisting of 3 large 
white? leaves. 
Specses. 1. sylvatica. It is extremely doubtful whe- 
ther this singular grass of Guianne has ever yet been found 
in the United States. Mr. Kinn, said to have been the dis- 
coverer by Mr. Pursh, on being questioned regarding it, 
by my friend Zaccheus Collins, Esq. produced the Ca- 
rex Fraseri asthe identical plant shown to Mr P.; I have 
been, however, induced to insert it for future examina- 
tion, as it may probably yet be discovered in some bi a 
mity of the Southern states.
