9C6887EDC54BFFE6FFE9FA09FBB5F8CB.taxon	discussion	Notes. – Grey-Wilson (1980) lists the type locality erroneously from the eastern Democratic Republic of the Congo (“ Eastern Zaire ”). The Rukarara is one of the sources of the Nile and now situated in Nyungwe National Park, Rwanda. Impatiens purpureoviolacea s. str. is confined to Nyungwe Forest and could not be recorded in Gishwati-Mukura National Park or in the Volcano National Park, the former Albert National Park that continues in the eastern Democratic Republic of the Congo (Virunga National Park) and southwestern Uganda (Mgahinga National Park). Despite the overall floristic similarities between Nyungwe and Bwindi Impenetrable Forest in southwestern Uganda, I. purpureoviolacea has also never been recorded there.	en	Fischer, Eberhard, Abrahamczyk, Stefan, Holstein, Norbert, Janssens, Steven B.

9C6887EDC54FFFE0FC9BFD89FD9FFA4B.taxon	discussion	Notes. – Impatiens urundiensis belongs to the group with hairy ovary. It is a very distinctive species with the plants densely covered with brownish hairs, the stems erect, up to 60 – 95 (120) cm tall, the flowers large, upper lateral petal 18.5 – 24.5 × 11 – 15.5 mm, purple maculae on upper lateral petals small, spot-like, ovary and fruits with brownish hairs. In contrast to all other species that occur in submontane to montane rainforest, it is confined to gallery forests in grassland. The petals display a sweet odour.	en	Fischer, Eberhard, Abrahamczyk, Stefan, Holstein, Norbert, Janssens, Steven B.

9C6887EDC556FFFAFF19FE69FD88FA2B.taxon	discussion	Notes. – This new hydrid was already mentioned by Troupin & Grey-Wilson (1983) as occurring in clearings of montane forest near Uwinka at 2400 m. 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.	en	Fischer, Eberhard, Abrahamczyk, Stefan, Holstein, Norbert, Janssens, Steven B.
