Population

Ceropegia occulta is an extremely rare species, known from only a few collections, but plants are cryptic and possibly overlooked. Known records of this species are from the area between Worcester and Robertson. Dyer (1980) mentions one collection from Suurbraak near Swellendam that may possibly be this species, pending further taxonomic study.
