Small shrub to 50 cm tall; stems erect, reddish. Prickles 5–9 mm long, straight, scattered, 4–10 per 10 cm of stem in the few collections seen and a few on the mid-vein on the upper and lower surface of the leaves. All parts glabrous except for minute papillose hairs in leaf axils and towards the apex of the corolla lobes.

Leaves 2–6 cm long, the lamina 2–4 mm wide, broadly lanceolate in outline but the lamina deeply lobed with (1) 2 or 3 (or 4) lobes on each side, rarely reduced to 1 pair or absent; lower lobes shorter than mid lobes; lobes 5–15 mm long, 2–5 mm wide, the sinuses between the lobes rounded.

Inflorescence a short cyme c. 1 cm long bearing 1 or 2 prickles and 4 or 5 flowers; pedicel c. 7 mm long; calyx lobes c. 3 mm long, c. 2 mm wide at base, acumen 1 mm long; corolla deeply divided almost to base, pale mauve; lobes c. 7 mm long, c. 2 mm wide; anthers c. 3.5 mm long, c. 1 mm wide, sessile, poricidal; ovary globular, 1.5 mm diameter; style 4–5 mm long.

Fruiting pedicel c. 12 mm long, slightly thickened distally; calyx not much enlarged in fruit; berry c. 1 cm diameter (few fruits seen), red. Seeds broadly reniform in outline, c. 4 mm long, flattened.

Distribution and ecology

Found in south-eastern Qld in the Biloela-Banana-Baralaba area. It occurs on heavy cracking soils, often in association with brigalow, Acacia harpophylla, or Eucalyptus thozetiana (Bean 2004). 


Solanum dissectum is one of the unusual species of subgen Leptostemonum which  has prickles but lacks stellate hairs, a characteristic shared with S. pugiunculiferum  from northern Australia.

S. dissectum is considered to be part of the red-fruited S. ferocissimum group of subgen. Leptostemonum with its closest relationships to S. ferocissimum and the recently described S. lythrocarpum . It differs from both species by its complete lack of stellate hairs and its deeply lobed leaves.

S. dissectum is placed in the S. ferocissimum group together with S. chenopodinumS. corifoliumS. discolor, S. defensum, S. dryanderense, S. dysprosiumS. ferocissimum, S. fervens, S. inaequilaterum, S. latens, S. lythrocarpum, S. mentiens, S. parvifolium, S. shirleyanum, S. stelligerum and S. yirrkalense (Bean 2004).
