BOTANY OF SOUTHERN RHODESIA 435 
BURSERACES. 
CoMMIPHORA sp. 
Matopo Hills, kopjes, general. Fl., with immature leaves, 
Oct. 197. Also at the Victoria Falls. 
A small tree, always growing between rocks, sparingly 
branched. It forms one of the most striking vegetative objects in 
the dry season, in the Matopo Hills and on the Zambesi gorge 
below the Victoria Falls, on account of the light papery bark, 
which is constantly peeling off in thin laminæ, showing the green 
cortex beneath. The leaves are7-foliate, and the flowers $ sessile, 
aggregated towards the top of the peduncle, which at first very 
short, subsequently elongates considerably. There is an un- 
named specimen of this plant in the Kew Herbarium, collected by 
Mr. T. Baines on the Shashi river, Rhodesia. It is probably a 
new species, but the available material is not sufficiently mature 
to permit of description.
