Huilla, prope Bumbo, ad rivulum, Jun. 1860, no. 6889. 
This species is closely allied to C. tristis, Kunth, but differs in the habit and appressed 
muticous glumes. The culms are 4 inches to 1 foot in height, rising from a tuft of 
brown membranaceous leaf-bases, with a few younger stiff glaucous leaves; the spikelets 
are numerous, and reach the length of 4 inch. The nut was very young, and only 
lof the scale in length. The variety aphyllus seems to bear the same relation to the 
leafy form that С. denudatus, Vahl, does to C. spherospermus, Schrad. The stem- 
leaves are reduced to their sheaths, while the involucral leaves, two in number, are short 
and erect, one of them continuing the culm, so that the umbel appears lateral. The 
spikelets are rather narrower and darker than in the typical form, and the culms closer 
together on the woody rhizome. 2
