Euphorbia horrida Boiss., Cent. Euphorb. 27 1860. (Syn: Euphorbia horrida var. major A.C.White, R.A.Dyer & B.Sloane; Euphorbia horrida var. noorsveldensis A.C.White, R.A.Dyer & B.Sloane; Euphorbia horrida var. striata A.C.White, R.A.Dyer & B.Sloane);
Euphorbia horrida (African milk barrel) is a species of flowering plant in the family Euphorbiaceae, native to South Africa.
It is a cactus-like shrub showing remarkable similarities to the true cacti of the New World, and thus an example of convergent evolution. Growing to 1.5 m (4 ft 11 in), it has blue-green, heavily-ridged spiny stems carrying solitary green flowers in summer. In temperate regions it must be grown in heated conditions under glass. It develops new shoots laterally at the base of the plant (offsets), often forming roots and thus a successful means of propagation.

Yes, it looks like Euphorbia horrida Boiss., found in Cape Province of South Africa. However, this species is closely related to E. polygona Haw. The two species are often difficult to distinguish.
