Note
According to previous descriptions of C. setifera (e.g. Lye in Haines & Lye 1983), the culms are sparsely to densely hairy. After careful examination of the specimens from the Flora area, I discovered that all the Kenyan specimens have glabrous culms, while those of the Tanzanian specimens are at least sparsely hairy. Tanzanian specimens sometimes are villous on the culms, leaves and peduncles, noticable with the bare eye.

Native to:

Kenya, KwaZulu-Natal, Madagascar, Malawi, Mozambique, Northern Provinces, Swaziland, Tanzania, Zambia, Zaïre, Zimbabwe
