This species, from the southern Arabian Peninsula, forms a large shrub with triangular, spiny branches. It is sparsely branched, which makes for an interesting looking plants, and the spines are infrequent. The cyathia are yellow. Silly us, we once thought this species was rare, then we went to Yemen and found it all over the place. We offer rooted cuttings of this species in one-gallon pots.
