First described in 1993, Euphorbia cedrorum is referred to as a coralliform euphorbia because of the crown’s resemblance to ocean coral (1) (4) (5). Well-adapted to a dry climate, E. cedrorum has a woody trunk with succulent, cylindrical branches (4). Although appearing leafless, it does have tiny leaves, which are shed to leave small, circular leaf scars (2) (4) (5). Like other Euphorbias, E. cedrorum has highly specialised inflorescences, known as ‘cyanthia’, which resemble true flowers from a distance (6). A dioecious species, each individual plant is either male or female, with the male cyanthia typically being clustered at the branch tips, while the female cyanthia are solitary (2) (4).
