Our specimen is without leaves, and must be compared with Panicum serratum, Br., 
a closely allied Cape species. Richard’s species occurs also in Abyssinia and Natal, and 
in other parts of Extratropical South Africa. It has been found by Burchell in the 
southern part of the Kalahari region as under :— 
Burchell, no. 2186, at the Kruman station, June 30, 1812. Burchell, no. 2543, on 
the road from Little Klibbolikhonni and the (Great) Kosi Fountain, December 20, 
1812; here Burchell also collected Indigefera heterotricha, DC., given in the enumera- 
tion above, page 18.

The type of this species belongs to the southern part of the Kalahari region of South 
Africa ; it was found by Burchell as under :— 
Burchell, no. 2391, on the rocks at the Chue Spring, October 7, 1812. 
Burchell, no. 2577, at the Kosi Fountain, December 24, 1812. 
Burchell, no. 2610, between Knegts Fontein and Klip Fontein, December 26, 1812: 
a stirps bipedalis, erecta, tota pubescenti-mollis ; folia ciliata; spiculæ dense albido-hirtæ ; 
locustæ petiolus ater; folia velutina ut etiam bases radicales; perennis ” (Burchell MS.). 
It was at this place and at this time that Burchell also collected Cyperus margari- 
taceus, Vahl, given in the enumeration above, page 26. This grass has also been col- 
lected by Baines in the South-African Gold-fields, 1870.
