This plant has somewhat the habit of one of the few-flowered J/arisci, while the 
spikelets suggest those of Ж. awrata, Nees. The spikelets are very few in number, and 
rather longer than those of most species of Kyllinga. The lowest glume is empty, and 
clasps the base of the second, which is longer and more distinctly mucronate, and 
subtends three stamens and a pistil. This glume also includes the third flower, entirely 
concealing it from the exterior, so that on opening the glume the third flower appears 
placed between the reproductive organs and glume of the second flower. The terminal 
flower consists of 3 stamens and a transparent palea-like glume. At the base of each 
spikelet is a small ovate scale or bract. The rhachis is not cylindrical as usual, but very 
slender and short, and somewhat flexuous. This structure is so unlike that of any other 
Kyllinga, that the plant should be placed in a distinct section of the genus. The style 
is stated by Dr. Welwitsch in his notes to be trifid; but all the flowers that I examined 
had bifid styles, as have the rest of the genus. It is possible it varies in this respect. 
In some capitula one of the spikelets has become viviparous, giving rise to a tuft of 
leaves, the remaining spikelets being abortive.

Allied to H. albivaginata, Boeckeler, but differs in the absence of setee and the shape of 
the nut. It frequently produces a short descending rhizome ; the culms are from 2 to 7 
inches in height, and more than 4 line in diameter. There are a considerable number of 
barren ones. The spikelet is small, the glumes pale, with the sides and base of the 
carina purple.
