Euphorbia rhombifolia is a species of Euphorbia indigenous to Namibia and South Africa, where it is widespread in clay-rich soils, extending as far east as Kwazulu-Natal.[1]

Description

Euphorbia rhombifolia in cultivation

It grows to 60 or 70cm in height, with a tuberous root-system that is often eaten by porcupines, and with thin (3-5mm), erect, grey, branching stems. The branches are dichotomous and taper to soft points.

The plants in the south-western Cape (E. caterviflora) are smaller, reaching only 30cm in height.

The leaves are small (1-3mm), dark, triangular and deciduous. The flowerheads are also small (3mm) and appear from winter into spring. [2]

This species is part of a group of closely related "stick euphorbias" including Euphorbia burmannii and Euphorbia tenax, which are widespread across southern Africa.[3]
