28. CYPERUS, sp. 
In our specimen, which is glabrous and without lower leaves, the stem is 6 inches long, 
smooth, striate, rather glossy and naked, at the apex with a pair of patent linear-subulate 
floral leaves 3-nerved and clasping at the base and rough-edged towards the apex, 
measuring respectively 3 and 11 in.; the sessile spikelets are 6 in number, and measure 
from 1 to 3 in., oblong or lanceolate-oblong, radiating in a hemispherical manner, com- 
pressed, 2-edged, glossy, reddish-brown in the dry state, 13-33-flowered ; the scales are 
rounded above with a short straight projecting apiculus, halfboat-shaped, with a small 
keel; the style is trifid, and the caryopsis ovoid, smooth, and very roundedly trigonous. 
It appears to be an undescribed species nearly related to Cyperus amnicola, Kunth, 
Boeck. in Linnea, xxxv. p. 509, п, 84, errore 83 (1868), and to C. rupestris, Kunth, 
Boeck., 1. с. p. 510, п. 85, which are Cape and Natal species.
