- n. Plural form of toothwort.
Sorry, no etymologies found.
"toothworts" (Dentaria), also in the mustard family, are the primary food source for the caterpillar stage of this butterfly.
The toothworts and broom rapes are Draconidæ, I think, and wholly parasites.
Invasions of garlic mustard are causing local extirpations of the toothworts, and chemicals in garlic mustard appear to be toxic to the eggs of the butterfly, as evidenced by their failure to hatch when laid on garlic mustard plants.
