Sp. Pl. 1: 187. 1753.
Herbs or shrubs, perennial, erect, sparsely to moderately armed, to 1.2 m, prickles cream to yellowish, straight, to 6 mm, sparsely to densely pubescent, hairs white to cream, sessile to short-stalked, stellate, 4(–8)-rayed, central ray 1–3(–5)-celled and to 3 mm, longer than lateral rays. Leaves petiolate; petiole 0.4–4 cm; blade simple, ovate, lanceolate, or elliptic, 2–15 × 2–10 cm, margins subentire, sinuate, or lobed with 1–4 lobes per side, sometimes very deeply lobed almost to midrib, lobe margins entire to coarsely lobed, base cuneate. Inflorescences extra-axillary, unbranched or rarely forked, 2–12-flowered, 2–9 cm. Pedicels 0.5–1 cm in flower, 1.2–1.8 cm and curved downward in fruit. Flowers radially symmetric; calyx somewhat accrescent, unarmed or with sparse prickles, 5–8 mm, moderately stellate-pubescent, lobes lanceolate to elliptic-acuminate; corolla white to pale blue or violet, stellate to stellate-pentagonal or rotate-stellate, 2–3 cm diam., with interpetalar tissue at margins and bases of lobes; stamens equal; anthers narrow and tapered, 4.5–6.5 mm, dehiscent by terminal pores; ovary glabrous or sparsely to moderately glandular-puberulent, rarely moderately pubescent, hairs white, stellate or simple. Berries light green with darker green mottling or pale greenish white, turning bright yellow, subglobose to depressed-globose, 1–2 × 1–1.8 cm, glabrous, without sclerotic granules.
