Streptocarpus occultus is a small monocarpic, unifoliate species originally thought to be another isolated population of Streptocarpus rimicola, but was then raised to species level in 1992 by Olive Hilliard. The species grows in rock fissures and caves under huge granitic boulders in grassveld in the south eastern Mpumalanga Province of South Africa, near the Eswatini (former Swaziland) border.
S. occultus has small leaves (10-20 mm wide x 30-50 mm long) and small faint pink to white flowers (15 mm long). It is threatened by exotic tree plantations which have been planted and replace the grassveld thereby given more shade to localities and reducing water runoff when it rains.
