Figures
Fig 15, p 40
Ecology
Crevices of large boulders; 900–1600 m
Conservation
Least Concern (LC), but apparently uncommon in the Flora area as is known from only two collections from Uganda and three from Tanzania
Note
It is remarkable how constant is the occurrence of these plants on exposed rock crevices that seem scarcely able to support any plant life.
Distribution
Flora districts: U1 U3 K1 K4 K6 K7 T3 T5 T7 Range: Nigeria, Sudan, Ethiopia, Zambia, Malawi, Mozambique, Zimbabwe
