Despite the overall floristic similarities between Nyungwe and Bwindi Impenetrable Forest in southwestern Uganda, I. purpureoviolacea has also never been recorded there.</p> </div>	http://treatment.plazi.org/id/9C6887EDC54BFFE6FFE9FA09FBB5F8CB	Public Domain	No known copyright restrictions apply.

Western Province, Nyungwe National Park, near source of Rukarara, 2250 m, E.

It has been observed there by the first author in 1985, vegetatively more resembling Impatiens purpureoviolacea but with clearly intermediate flowers. Grey-Wilson (1989) described this new hybrid, hitherto only known from one locality in Rwanda (Uwinka) and he stated that “there is little doubt […] that the parents are I. gesneroidea var. gesneroidea and I. purpureoviolacea ” (Grey-Wilson, 1989: 717). However, he did not name it formally. In 2017, the hybrid was again collected at the type locality of I. purpureoviolacea growing as a single individual and apparently not as hybrid swarm between its parents I. purpureoviolacea and I. gesneroidea. It has been observed only as a rare plant in single individuals.</p> </div>	http://treatment.plazi.org/id/9C6887EDC556FFFAFF19FE69FD88FA2B	Public Domain	No known copyright restrictions apply.
