This medium-sized shrub is a bit of a puzzle, its origin unknown except the nod to Edward Hummell, a now gone succulent plant propagator. It definitely has some influence from Euphorbia grandicornis, but beyond that it is anyones guess. No doubt the cyathia are yellow or white, but We’ve never seen them. This is a crested plant that is quite nice. These plants are rooted cuttings in 4-inch pots.
