A new species of Crassula (Crassulaceae subfam. Crassuloideae), C. stylesii that belongs in C. sect. Rosulares, is described from the Maputaland-Pondoland Region of Endemism in KwaZulu-Natal in southeastern South Africa. Crassula stylesii shows similarities with the autonymic varieties of C. setulosa and C. obovata. However, it grows taller than both these species, and pseudo-rosettes do not develop basally in the case of C. stylesii, but are characteristically present in both C. setulosa and C. obovata, particularly the former. Crassula stylesii is illustrated and differences among the three species are tabulated.
