According to extant taxonomy, this is merely Euphorbia trigona, a species of unknown origin but thought to be either from India or Angola because of its affinity to other species in those countries. E. hermentiana is a different plant altogether, with 3- to 4-angled stems that typically are 1-3 inches in diameter, or much larger than the typical E. trigona. Like that species, however, E. hermentiana produces green leaves at the apical tips when growing. These plants are rooted cuttings in 8-inch pots.
