Antirrhinum (family Scrophulariaceae) A genus of herbs in which the lower leaves are opposite, the upper leaves alternate, and all are simple. The flowers are borne in racemes and have strongly 2-lipped corollas, the lower 3-lobed lip having a projecting bulge or ‘palate’ which closes the mouth of the flower; the tube is unspumed, but with a swelling below. A. majus (snap-dragon) is cultivated in many coloured forms and has been naturalized beyond its southern European natural range. There are 42 species, most Mediterranean, but also occurring in western N. America.
