Toadflax

Toadflax, the popular name for the scrophulariaceous genus Linaria, derived from the flax-like foliage of the common species L. vulgaris, the prefix toad- being a contemptuous indication of its valuelessness for fibre. This genus is distinguished from the closely-allied snapdragons (Antirrhinum) by the corolla having a spur in lieu of a pouch.
