Synonymy

Solanum gympiense Symon, Austrobaileya 4: 433–435 (1995)

T: Wide Bay District: Gundiah, Qld, 21 June 1927, C. T. White 3527; holo: BRI.

Solanum sp. 2, Fl. S.E. Qld 2: 418 (1986).

Description

A shrub to 1 m high, unarmed, with dense indumentum of stellate hairs, central cell as long as or much longer than lateral cells, somewhat floccose, sometimes viscid, one report says plants aromatic.  

Leaves broadly elliptic, (3-) 6–12 cm long, (2.5-) 4–7 cm wide; apex acute; base rounded; margins with shallow broadly triangular to rounded lobes, more rarely undulate-sinuate; petiole (0.5-) 1.4–3.0 cm long.  

Inflorescence a short cyme of 2–6 flowers from a mid to upper internodal position; peduncle (to first flower)5–20 mm long; rachis 5–25 mm long; pedicel c. 8 mm long; calyx c. 5–7 mm long, the lobes flattened, narrow, elliptic; corolla to 3 cm diameter (few available), stellate-rotate, divided nearly halfway, the lobes broadly triangular, pubescent outside, purple blue; staminal filaments short; anthers c. 5 mm long, slender, tapered upwards, poricidal; ovary broadly conical, glabrous; style c. 6 mm long.  

Berry globular to apiculate, 5–7 mm diameter, red at maturity; calyx lobes then elliptic, 7 mm long, 2.5–3 mm wide flattened, sub-leafy. Seeds irregularly discoid or flattened and sub-triangular to sub-reniform in outline, 2–2.5 mm long, minutely reticulate.

Distribution and ecology

South-eastern Qld with most collections from between Rosedale and Cooroy but with an interesting disjunction in the Carnarvon Range area and south-westward towards Mitchell.

Relationships

The species is closely related to S. densevestitum F. Muell. from which it differs in its broadly elliptic leaves, shallow leaf lobing generally present and the presence of a peduncle bearing several flowers. There may also be a slight difference in fruit shape but this requires more field work to confirm.

Treated as part of the S. densevestitum group of the subg. Leptostemonum (Bean 2004), together with S. densevestitum, S. hapalum, S. innoxium, S. johnsonianum, S. nemophilum and S. ultimum .

Distinctive within the S. densevestitum group of subgen. Leptostemonum by its gland-tipped stellate hairs and lobing of the adult leaves.

Derivation of epithet

The epithet gympiense is a reference to the Qld town of Gympie and the area in which it occurs naturally.
