Leaves are ovate-lanceolate or broadly ovate, acute or acuminate, unequal at the base and often cordate, entire or dentate, sub-glabrous or with greyish tomentum, generally glandular in a long petiole of up to 10 cm in length. Flowers often double or triple. Calyx is inflated towards the middle, persistent and reflexes in fruit. Corolla is about twice as long as the calyx, white or tinged with green, pubescent outside and with the 10 toothed limb. Capsule is globose, tuberculate or muricate, borne on a short thick peduncle, which, unlike that of D. stramonium, is never erect but nodding. It dehisces irregularly exposing a mass of closely packed, light brown, flat seeds which nearly fill the interior.
