South Central. 7. Baines! ‘ i 
A curious form, of which I have seen male flowers only. South African specimens 
of it eccur mixed with those of Uucumis dissectifolius, Naud. in Herb. Hook, Sonder 8 
. Naudinianus consists of flowering specimens of this and fruiting of C. dissectifolius, 
Naud.; these two plants being so similar that the flowers (themselves black and ob- 
scure) alone distinguish them. It is probably a desert form of C. Colocynthis or C.
