Although its Japanese name is "Onikaku Kirin,)" this is an extremely rare Euphorbia that's barely ever seen in Japan—there's basically no distribution here, and you won't find much confirming information even if you search for it. It's an endemic species from the central-northern part of Limpopo Province, South Africa. In its native habitat, it grows into a mid- to large-sized tree. The plant's body is striking because its center is deeply indented and the ribs are very prominent—if you cut across the stem, you'd see a cross-shaped star. It has spines on each rib, so in this respect, it's quite similar to Euphorbia canariensis E. canariensis and Euphorbia pseudocactus E. pseudocactus , while the presence of white vertical lines down the body is reminiscent of Euphorbia greenwayii E. greenwayii and Euphorbia confinalis E. confinalis . That said, the spines here are on a whole other level of fierceness (although, in some photos, it's actually hard to tell it apart from canariensis). One more detail: those vertical lines vary by plant, and may or may not appear depending on the season.
