形態特徵
- Mostly armed shrubs to 1.5 m tall, pubescent overall with stalked stellate hairs; older stems with copious, dark or yellowish, stout, broad-based, mostly curved prickles 2–10 mm long.
- Leaves solitary or in somewhat unequal pairs, ovate, 7–18 cm long, 3–12 cm wide, apex acute or slightly acuminate, base truncate or obtuse, often dimidiate, mostly 4-lobed on each side, the lobes ascending, often salient and acuminate, upper surface with scattered, sessile, stellate hairs, often glabrescent, lower surface softly tomentose with dense, whitish, short-stalked hairs, often drying discolorous, lateral veins ascending at 45 degrees, branched on each side as they enter the lobes; petiole 2–7 cm long.
- Inflorescences extra-axillary, many-flowered cymes; peduncle commonly 1–3-branched, 1–3 cm long, yellowish tomentose with stalked stellate hairs; pedicel 4–8 mm, tomentose. Calyx 3–5 mm long, tomentose, lobes narrow, ca. 1 mm long before splitting to become 2.5–3 mm long; corolla blue or purple, rotate, 1.5–1.8 cm long; filaments 0.5 mm long; anthers narrow, 4–6 mm long; apex of ovary and base of style with short simple and stellate, sometimes glandular hairs.
- Berry red, 5–8 mm across; fruiting pedicel erect, 1–1.5 cm long, tomentose; fruiting calyx tomentose, not enlarged; seeds buff colored, discoid, 2 mm across.
- This species is quite similar to <i>Solanum peikuoense</i>, which has longer calyx lobes, glabrescent pedicels, and is less pubescent overall. <i>Solanum macaonense</i> is restricted to lowland sites, below 500 m, while <i>S. peikuoense</i> occurs above 1,000 m.
