Inflorescences racemose, spicate , or subcapitate , rarely 1-flowered; bract 1, usually similar to leaves; bractlets 2, adnate to base of calyx or pedicel. Flowers bisexual , subsessile or pedicelled. Calyx tubular, cupular, or campanulate , (3 or) 4-6-lobed, 2-6-parted, 6-toothed, or spathelike, sometimes absent or of 3 free sepals. Corolla bilabiate, usually curved , sometimes tubular-campanulate or funnelform with 5 subequal lobes ; upper lip entire, emarginate , or 2-lobed; lower lip 3-lobed. Stamens 4, didynamous , inserted at base of corolla tube ; filaments slender; anthers 2-celled, dehiscing longitudinally, sometimes 1 cell fertile and another sterile or reduced to spur. Pistil 2- or 3-carpellate; ovary superior; placentas 2-4 or 6(-10), parietal or sometimes axile at ovary base; ovules 2-4 or numerous , anatropous . Style long; stigma inflated , discoid , peltate, or 2-4-lobed. Capsule usually dehiscing loculicidally by 2 or 3(or 4) valves . Seeds minute, testa pitted or reticulate .

About 15 genera and 150 species: North Temperate regions , less represented in Africa, America, Asia, and Australia; nine genera and 42 species (nine endemic) in China.[1]
