Abstract

We describe and illustrate the new species Impatiens butu Gavin-Sm. (Balsaminaceae) from the South Pare Mountains and I. ndovu Gavin-Sm. from the Nguru Mountains of Tanzania and compare them with morphologically similar and sympatric species of Impatiens L. Both localities are within the Eastern Arc Mountains of Kenya and Tanzania, a well-known center of plant species richness and high endemism.
