Bastard Toadflaxes
Thesium
Thesium is a genus of flowering plants in the family Santalaceae. It is particularly well represented in South Africa, where roughly half the species occur. Nickrent and others argue that the genera Austroamericium Hendrych, Chrysothesium (Jaub. & Spach) Hendrych, Kunkeliella Stearn, and Thesidium Sond should be considered as part of this genus.
Species in this genus are parasitic on roots. Fruits of Thesium species are nutlike achenes.
