Description

Glabrous or pubescent herbs. Stems (plants rarely acaulescent) erect, ascending, or repent, simple or branched, terete or subquadrangular (sometimes winged), glabrous or pubescent. Leaves opposite, usually petiolate; margins entire; without cystoliths. Flowers sessile or short-pedicellate, few or numerous, in terminal or axillary, loose or compact spikes or capitula, spikes sometimes branched at base, lower bracts leaf-like and always opposite, upper ones usually alternate, each bract subtending a single flower with 2 bracteoles; bracteoles about as long as bracts but much narrower. Calyx deeply 5-lobed, posterior lobe oblong, usually conspicuously longer and broader than others, 3-veined, hygroscopic in fruiting stage, recurved in a dry atmosphere, anterior pair usually linear, wider than setaceous lateral pair; corolla usually white, red, purple or yellow, with a cylindrical or funnelform tube, limb subregular or 2-lipped, upper lip 2-lobed and much shorter than 3-lobed lower lip, latter curved inward in bud and overlapped by upper lip; stamens 4, usually included, staminode usually present between posterior pair, anther 2-thecous,theca ovate, subequal, muticous; disk inconspicuous; ovary with numerous ovules in each locule, style filiform, stigma 2- or 3-lobed, lobes unequal. Capsule oblong, obtuse, nonstipitate, seedbearing nearly its entire length, valves with 25-30 seeds, without retinacula; seeds numerous, minute, subglobose, areolate, with mucilaginous trichomes, when moistened, flung away by incurving margin of valve at dispersal.
