Description
Herbs, whorled or alternate rarely opposite, entire leaves. Flowers lavender, pink, white or yellow, in racemes or spikes, terminating the branches or in terminal corymbs. Flowers perfect, zygomorphic, with 3 small sepals, frequently one of these slightly larger than the others, and 2 larger petaloid sepals (wigs). The 3 petals are united into a tube, 3-lobed at apex, the 2 lateral lobes usually the longer, the center lobe usually lacerate, often thicker in texture; stamens 6-8, united to the corolla tube in 2 rows. Capsule 2 –locular, with one seed in each locule. Seeds dark brown or black, ellipsoid or ovoid, rarely globose, 0.5-3 mm long, usually densely pubescent. The genus has been divided into several genera none of which have distinct characteristics. Orange flowers turn pale yellow on drying, yellow ones bluish green; the pink or lavender ones remain the same color or fade slightly."Glabrous biennial or weak perennial herb, 3-5 dm tall, from a tap root; branches erect, slightly radiating from a crown, stems uniformly leafy. Leaves alternate, linear-oblong to oblong-spatulate, 1.5-4 cm long, revolute, apex usually with a sharp mucro, racemes 5-25 cm long; bracts deciduous. Sepals green, with pink or white margins, ca. 2 mm long, wings pink, elliptic 4-6 mm long, tapered to claws; corolla slightly shorter than the wings, fringed; stamens 8. Cleistogamous flowers in racemes from the base of the plant, either below or just above the surface of the soil, rarely from the lower leaf axils. Seeds black, ca. 3 mm long, densely short-pubescent; aril 2-lobed ½ as the seed body.
