From the North-East Province of Kenya, and endemic on the Marsabit Massif on volcanic slopes (hence the name), this densely branched shrub has 4-5 angled stems with continuous spine shields and stout paired spines. What makes this species very desirable in collections are the cyathia, which are yellow-orange and showy on those stems. These plants are rooted cuttings in 5-inch pots.
