Annual, biennial or perennial herbs, caulescent, with a taproot or woody branching caudex, occasionally with rhizomes. Stems one to several, simple or much branched. Leaves alternate, basal rosette leaves largest, decreasing in size upward, entire or toothed, often lyrate below, shortly petiolate below to subsessile above; stipules absent. Flowers perfect, zygomorphic to sometimes actinomorphic, forming a spicate raceme, not leafy, opening near sunset or near sunrise. Floral tube distinct, cylindric, deciduous soon after anthesis.

Ovary with (3 or) 4 locules, with 1(or 2) ovules per locule; stigma divided into (3 or) 4 short linear lobes, receptive all around, and subtended by a ± conspicuous ringlike indusium. Fruit an indehiscent nutlike capsule with hard walls, broadly fusiform to subcylindric, terete to sharply (3 or) 4-angled, sessile or basal portion sterile and stipelike.

Leaves alternate or in a basal rosette that often is absent in mature plants, entire, toothed to pinnatifid; stipules absent. Flowers perfect, actinomorphic, in axils of upper leaves, when numerous forming terminal leafy spikes, racemes, or corymbs, opening near sunset or near sunrise. Floral tube usually well developed, cylindric and somewhat flared near mouth, deciduous soon after anthesis. Sepals 4, green or yellowish, often tinged or striped red or purple. Petals 4, yellow, purple, pink, or white. Stamens 8; anthers versatile; pollen shed singly. Ovary with 4 locules; ovules numerous; stigma divided into 4 linear lobes, receptive all around, and subtended by a ± conspicuous ringlike indusium in early development, but often obscured when receptive. Fruit a dehiscent capsule [rarely indehiscent outside of China], straight or curved, terete to 4-angled or winged, sessile, occasionally pedicellate, or basal portion sterile and stipelike. Seeds numerous, in 1 or 2(or 3) rows or in clusters in each of 4 locules. 2n = 14, 28, 42, 56.^[3] [more]
