形態特徵

• Usually armed, andromonoecious herbs or subshrubs to 2 m tall, pubescent with stalked many-rayed stellate hairs; prickles mostly flat and straight; stems and branches shaggy tomentose, glabrescent and prickly.
• Leaves unequal-paired, ovate or elliptic, 5–12(–14) cm long, 4–7 cm wide, apex acute or obtuse, base obtuse or truncate and often oblique, 5(–7)-sinuate lobed, tomentose on both surfaces with stalked and sessile, many-rayed hairs, veins with short stout prickles; petiole 1–4 cm.
• Inflorescences extra-axillary, few-flowered scorpioid racemes, 2.5 cm long; peduncle very short; pedicel 0.5–2 cm long. Usually only one flower fertile; calyx campanulate, 1–1.5 cm long, lobes triangular-lanceolate, 2 mm long, hairy; corolla purple-blue or white, stellate-rotate, 1.5–3 cm long; filaments 1.5–1.8 mm long, glabrous, anthers ellipsoid, 5–8 mm long.
• Berry solitary, yellow, globose, 2–3 cm across, glabrous; fruiting pedicel 2.5–5 cm long, deflexed; fruiting calyx slightly enlarged, hairy, prickly; seeds lenticular, 2–3 mm across.
• This species was long known as <i>S. incanum</i> L. That name applies to a different species from northeast Africa and the Arabian Peninsula that has more pubescent leaves with narrower apices and smaller fruits. The application of the name <i>S. undatum</i> or <i>S. cumingii</i> to this species is uncertain. In some countries, this species occasionally hybridizes with the cultivated eggplant (<i>S. melongena</i>).
