Streptocarpus wittei occurs in the vicinity of Lukafu in gorges draining the Kundulungu Plateau north of Lubumbashi, Katanga Province, south eastern Congo, and then again with a significant disjunction (about 700 km) near Chowo on the Nyika Plateau on the border between northern Zambia and Malawi. Streptocarpus wittei, of which the “w” should be pronounced like a “v” is a large monocarpic, unifoliate species, leaf about 250 x 280 mm, with many large flowers (50 – 60 mm) per inflorescence, dark violet with darker violet and yellow throat markings. It habitat is likely to be forest in the Lukafu vicinity but on the Nyika Plateau it occurs on rocky outcrops. More fieldwork is required to compare the morphology and DNA sequences of the two isolated populations to establish whether this species should be split into two.
