Ursinia anthemoides (f). This plant was also found in small 
numbers on other parts of the area, 
Gazania pinnata (o). 
With regard to the vertical range of these plants, the majority gradually 
diminished in numbers towards the top of the area. There were a few 
exceptions to this general rule. Hypoxis serrala was present on the higher 
slopes only. Oxalis cernua, which was present on the lower slopes 
of the area, was replaced towards the top by the closely related species 
Oxalis sericea. The orchids, with the exception of Pterygodium catholicum, 
were all confined to the lower slopes.
