Corolla limb usually 2-lipped; upper lip 2-lobed and lower 3-lobed, rarely upper lip entire and lower 4-lobed, also rarely limb (4- or) 5-lobed; tube hairy annulate inside. Stamens epipetalous , 4 or 2, free , rarely filaments connate , sometimes one staminodial; anther 1- or 2-celled, usually dehiscing longitudinally; disc persistent. Ovary superior, 2-celled and each cell 2-ovuled and style subterminal , or ovary 4-parted and each lobe 1-ovuled and style gynobasic (from bases of ovary lobes) with 2-cleft apex. Fruit usually 4 dry nutlets . Seeds with or without endosperm.

Approximately 3500 species in 220 genera, distributed worldwide, but mostly in the Mediterranean region and SW Asia. China has 807 species in 96 genera.[1]
