ISI 2025-23. Euphorbia rowlandii R.A.Dyer

This elegant euphorbia has been in cultivation since shortly after its description by Dyer in Bothalia 7(1): 28 – 29 (1958). It has been mostly grown by Euphorbia specialists and Botanical Gardens but is deserving of wider distribution. Mature plants in habitat are low shrubs 1 to 2 m tall, branching primarily from the base to produce a mass of ascending, jointed branches. The joints are thickest where they initiate and gradually taper to the next joint. This and the finely speckled epidermis make even a rooted cutting an attractive specimen. Furthermore, the 5 to 6 ribs are lined with continuous pale thorn shields bearing paired spines every centimeter or so, and bright yellow cyathia in the spring. We offer rooted cuttings of HBG 45128, a plant received from Grigsby’s Cactus Garden, February, 1981. It is known only from northern Limpopo Province, South Africa, and perhaps adjacent Zimbabwe. Much of its range is contained within Kruger National Park. The first recorded specimen of the species was made in 1949 by Dr. L. E. Codd. Flowering and fruiting material was subsequently provided to Dyer by Lt. Col. Rowland Jones, then in charge of the northern sector of Kruger National Park, after whom the species was named. $10.
