Euphorbia inermis is closely related to Euphorbia esculenta but the branches (fingers) are generally longer and thinner than those of the latter. In both species the tuberous root is distinct from the main stem and the bracteoles are woolly white.
The plants are distributed from around Uitenhage to the Fish River Valley. The peduncles of Euphorbia inermis are shorter than those of E esculenta and the styles are almost fully joined into a slender column.
Propagation is from seed.
