This is a very small species, with somewhat the habit of Scirpus hamulosus, Stev., 
about 1 or 14 inch high, with narrow leaves } inch in length or less. The involucral 
leaves are usually longer and broader than the radical leaves, and attain a length of one 
inch; the bases are broadly ovate, with several rather prominent ribs, which are some- 
times forked, as in 4. capensis. "The capitula are closely compacted, and resemble those 
of a small Kyllinga. The flowers are very small and narrower than in A. capensis. 
The three-cleft style, with the bluntly triquetrous nut, also serve to distinguish it from the 
other species. As it has three spikelets, it must be referred to the section Kyllingioides, 
which includes also Platylepis braziliensis, Nees. 
The remaining species of the genus are also Tropical African, one of which occurs 
besides in South America.
