Lower Guinea. Angola: Huilla ; in the cold rapid mountain streams of 
Morro de Lopollo, 3800-5800 ft., Welwitsch, 2458 ! 
According to the notes with Welwitsch’s specimen, this plant forms a green carpet 
on the beds of the streams under the water, and rarely flowers, the heads being 
frequently viviparous, when their peduncles bend down and produce young plants, 
forming the so-called stolons. It is allied to Z. Woodii, N. E. Br., from Natal.
