Streptocarpus pentherianus is a perennial species with up to three dark green leaves (to 120 x 84 mm), sometimes reddish below and small white keyhole shaped flowers, corolla 18 mm long, sometimes with suffused pale violet or yellow in the throat and with the tube usually suffused with violet. It occurs over quite a large range, at altitudes above 1200 m above sea level from southern KwaZulu Natal Province, South Africa, in the south through the whole of the inland and higher altitude areas of that province and further north into Eswatini (former Swaziland) and Mpumalanga Province in South Africa. It does not vary over the whole of its range except for flower colour.

Streptocarpus pentherianus often grows with Streptocarpus pusillus which also has white flowers but they can be distinguished quite easily because Streptocarpus pentherianus has keyhole shaped flowers and Streptocarpus pusillus has tube shaped flowers.
