This new Euphorbia species, described by Ernst van Jaarsveld and Gerhard Marx from Zinnshoek (western Waterberg), is closely similar to Euphorbia cooperi, distsinguished by more slender, less deeply constricted segments along stems, finer leaves and flowering in summer-autumn, not winter as in cooperi. See here for a description of the species.
