Herbs annual [perennial], 0.3–2(–3)[–8] dm. Leaves mostly opposite, basal soon withering, sometimes in rosettes, distal cauline sometimes alternate, stipulate or estipulate, petiolate or sessile; blade usually 3[–5]-veined from base, margins sometimes revolute, surfaces hairy [glabrous], hairs sometimes clustered (stellate). Inflorescences racemiform [helicoid, scorpioid] cymes. Pedicels present; bracts [present or] absent. Flowers chasmogamous and cleistogamous, nodding or pendulous in bud. Chasmogamous flowers: sepals persistent, 5, outer smaller than [equaling] inner; petals 5, yellow, sometimes purple to brown at or near bases; stamens 10–15+; filaments distinct, outer stamens often sterile; carpels 3; styles 0; stigmas 1, ± sessile, hemispheric [obconic]. Cleistogamous flowers similar; petals 0; stamens 5–12. Capsules 3-valved. Seeds 6–50+ per capsule. x = 9.
