It was formerly considered congeneric with Maytenus, but more recent investigations separated it based on the presence of achyblasts and spines, alternate leaves or fascicles of leaves, an inflorescence that forms a dichasium, mostly unisexual flowers, and fruit forming a dehiscent capsule, with an aril on the seed. It is dioecious, with male and female flowers on separate plants.
