Euphorbia barnardii (live succulent)
It is a spiny succulent which is seldom higher than 0.75 m, with a sub-tuberous main root and much reduced stem which produces a few or many branches. These branches are 5- to 6-angled and constrict at intervals into segments up to 100 x 40-70 mm, and are usually thickest near the base. The spines are in pairs about 10 mm apart along the angles, up to about 10 mm long, closer together and shorter on the constricted portions of the angles. Leaves are rudimentary and deciduous (soon falling).
