The species name, “umbellata”, means “umbel-like” and refers to the flat-topped flower clusters. Bastard means false or of unusual shape or size, so sometimes Comandra umbellata is also called False toadflax. This plant is known to parasitize over 200 plant species and is also an alternate host for hard pine rust disease. It can reproduce sexually and also by spreading vegetatively. A single clone can cover a very large area. |
