I.C. Hedge
Annual (in ours) or perennial herbs. Stems erect, leafy with short eglandular hairs. Leaves not divided, crenate to serrate. Verticillasters in axils of middle and upper leaves forming loose or congested spike spike-like racemes. Bracts aristate or with marginal awns. Pedicels markedly flattened, erect. Calyx tubular, bilabiate, 15-veined; upper lip 3-dentate, median broadest; lower lip 2-dentate with lanceolate acuminate teeth; tube with or without thickened folds below sinuses; fruiting calyx closed by connivent lips. Corolla bilabiate; tube narrow, included in calyx; upper lip with 2 longitudinal folds within, scarcely hooded; lower lip 3-lobed. Stamens 4, included, didynamous, posterior pair longer than anterior. Style unequally bifid. Nutlets oblong, ± trigonous, smooth or punctulate, mucilaginous on wetting.
About 5 species in SW and C Asia; one reaching China. A very close relative of Dracocephalum and essentially only differing in the internal longitudinal folds on the corolla upper lip; also closely related to Nepeta and Glechoma L. (not in our area).
