Erect, ascensding or straggling perennial herb with stems usually to 1 m long, green or purplish-green, sparsely pubescent with simple hairs; prickles absent. Leaves ovate-lanceolate, 3–10 cm long, 2–5 cm wide, slightly discolorous, apex acute or obtuse, base cuneate, margins entire to shallowly lobed, both surfaces sparsely pubescent; petiole 1–3 cm long, usually winged in upper part. Inflorescences simple, forked or branched, to 24-flowered; primary peduncle 1–2.5 cm long. Flowers on pedicels to c. 10 mm long; calyx 2–3 mm long, lobes broad-triangular, 1–1.5 mm long, often rounded at apex; corolla stellate, 12–20 mm diam., white with yellow centre, often variously tinged violet; anthers 2.3–4.2 mm long. Berry globose, 6–9 mm diam., purplish-black, more or less glabrous; seeds c. 2 mm long, light brown; stone-cell granules to 0.5–1.2 mm wide. Flowers summer and autumn.

Both Henderson (1974) and Symon (1981) recognised Solanum douglasii in their accounts of Solanum in Australia. Subsequently, Purdie et al. (1982) excluded S. douglasii from their treatment, with a note that the species is inadequately known in Australia. It is unclear whether both species are present in Australia, or just S. furcatum (the earlier named species). Both species were recognised in Jeanes (1999). Many of the morphological characters used in Australian literature to separate the two species, in particular the supposedly discriminatory simple vs forked inflorescence appear to be unreliable and can vary within a population. On account of the difficulty in reliably separating the two species, only S. furcatum is recognised here, pending a better understanding of the Australian plants.
