Streptocarpus baudertii has very attractive keyhole shaped flowers very similar to those of Streptocarpus johannis. The flowers are projected forward so that they are almost completely flat which may be a landing platform for butterflies or other insects to pollinate them. The flowers, borne on short stout stalks, are quite variable, 32 – 50 mm long, medium violet, with 3- 7 deep violet lines, varying from one locality to the next with the largest found at the type locality near Cedarville, in southern KwaZulu-Natal Province (KZN) and the smallest ones from Kwelegha near the city of East London, Eastern Cape. The serrated leaves are arranged in a flat, neat rosette with many leaves (180 x 80 mm).
The species is only known from a few isolated localities such as Cedarville (KZN), and in the Eastern Cape in Ntywenka Pass near Tsolo, Collywobbles in the Mbashe River drainage and Kwelegha near East London, where a new botanical garden has recently been founded. It grows on rocky outcrops and steep cliffs. Genetic analyses have shown that this species has possibly evolved through the repeated formation of hybrids between Streptocarpus johannis and Streptocarpus meyeri (Ph.D. thesis, Margaret de Villiers, 2008) which would explain its variablity. The Streptocarpus meyeri has a flat rosette of leaves which is so similar to that of Streptocarpus baudertii that the two species cannot be separated unless they are in flower.
