Streptocarpus confusus was originally described by Olive Hilliard in 1966 in an effort to separate it from Streptocarpus haygarthii to which it is closely related, hence also its name referring to the confusion between the two species. A distinctive characteristic of the Streptocarpus confusus flower is the way the two upper corolla lobes are positioned relative to each other. Instead of the all five of the lobes pointing outwards evenly from the centre of the flower, the two upper lobes are positioned in such a way that they approach the horizontal. This results in a tight vertical narrowing of the opening of the corolla tube.
In 1968, Hilliard and Burtt described Streptocarpus confusus ssp. lebomboensis to separate a long flowered form from the originally described short flowered form of the species. Both subspecies are apparently more drought resistant, and therefore able to occupy habitats that other Streptocarpus species cannot grow in. Both subspecies of Streptocarpus confusus are monocarpic and unifoliate with leaf dimensions up to 300 x 170 mm.
Streptocarpus confusus ssp. confusus occurs over quite a large range from inland central KwaZulu Natal Province, South Africa in the south, across Eswatini (former Swaziland) to Mariepskop in Mpumalanga Province, South Africa, in the north. It grows in isolated forest patches or on cliff faces on gorge walls. Streptocarpus confusus ssp. confusus has smaller flowers than S. confusus ssp. lebomboensis. The flowers are pale to deeper mauve keyhole types (25 mm) and have a club shaped stigma.
