in botany, a genus of the didynamia angiopermia class. The calyx consists of five leaves; the basis of the corolla is bent backwards, and furnished with pectoria; the capsule is bilocular. There are 14 species of the antirrhinum, 10 of which are natives of Britain, viz., the cymbalaria, or ivy-leaved toad-grass; the elatine, or sharp-pointed fleuillin; the spurium, or round-leaved fleuillin; the arvensis, or corn-blue toad-flax; the repens, or creeping toad-flax; the monoppermum, or sweet-smelling toad-flax; the linaria, or common yellow toad-flax; the minus, or least toad-flax; the majus, or greater snapdragon; and the orontium, or least snapdragon. The linaria is said to be cathartic and diuretic; but it is not used in the shops.
