Commiphora glandulosa, the tall firethorn corkwood or grootdoringkanniedood in Afrikaans, is usually a single-stemmed tree of up to 10 m. The distribution area of this tree lies largely in the tropical terrain to the north of South Africa, but the habitat reaches south of the Limpopo as well as in small border areas of Mpumalanga and Kwazulu-Natal.
The tree has a rounded crown and grey-green to yellow-green bark. The leaves cluster on small spur-branchlets. The flowers are small, pink or red and appear before the (winter) deciduous leaves in spring. The spherical fruit are about 1 cm in diameter and may remain on the tree throughout summer. Trees of this species are sometimes planted close together to form live fences (Coates Palgrave, 2002)
