Synonyms: Parquetina nigrescens (Afzel.) Bullock
Common names:
Frequency: Very rare in Zimbabwe.
Status: Native
Description:
Perennial climber with milky latex. Leaves opposite, somewhat discolorous.
Notes: Known only from one dying location on the Runde River in Gonarezhou National Park; only one plant seen recently.
Flowers or fruit in Zimbabwe unknown. All specimens so far collected have been sterile and the exact identity of the plants in our region still need further confirmation. Ours most likely concerns a different taxon called Omphalogonus calophyllus, which looks almost identical in vegetative state and has formerly often been confused with the true Periploca nigrescens.

Altitude range: (metres) 290 m (approx)
Flowering time:
Worldwide distribution: Fairly widespread in West-, Central- and East Africa to Mozambique and South eastern Zimbabwe.
