We review the Litanthus group of Drimia and describe a second species from Western Cape, Drimia stenocarpa, differing from Drimia uniflora in its invariably solitary leaf, larger flowers with narrower tepal lobes, longer and thicker pedicels, and distinctive cylindrical–prismatic capsule longitudinally banded in green and white. Both species are fully described and illustrated and a distribution map is provided.
