Notes.

1. New species record for DR. Congo.

2. This species belongs in the difficult group of C. bojeri - C. welwitschii , in which identification requires carefully collected underground organs. The collecting notes on the label of P. Compère 1991 mention the presence of tubers, but these have not been collected. Apart from tubers, the species differs from C. bojeri in having somewhat thicker and more pubescent leaves.

3. See note under C. welwitschii .
