This species, from near Jansenville in the Eastern Cape Province of South Africa, has a small main stem united with tuberous root to form an underground structure from which the branches grow. The branches are cylindrical, jointed, and spineless. These dioecious plants have cyathia glands that are tubular. Although this species is very similar to E. tubiglans, we?ve grown it outside in Tucson under a shrub for more than 8 years with little additional watering. This is one hardy Euphorbia, and we have multistemmed offsets in 5-inch pots.
