Tomato Bush; Wild Tomato; Nightshade
Usually flowers and fruits as a shrub about 1-2 m tall. Stems often armed with short spines.
Leaf blades mostly about 5-13 x 1.5-4.5 cm, stellate hairs present on both the upper and lower surfaces but denser on the lower surface. Petioles about 1-4 cm long, densely clothed in stellate hairs and likewise the twigs.
Inflorescence up to 20 flowered. Pedicels about 5-10 mm long. Calyx about 6-10 mm long, densely stellate hairy on the outer surface, lobes narrowly triangular, about 4-6 mm long. Corolla about 20-25 mm diam., outer surface stellate hairy, inner surface glabrous. Anthers about 4-6 mm long.
Fruits globular or depressed globular, about 10-15 mm diam., calyx lobes stellate hairy, persistent at the base. Seeds flat, about 2-3 mm long. Embryo +/- coiled, cotyledons no wider than the radicle.
Cotyledons +/- lanceolate, about 13-18 x 4-5 mm. First pair of leaves alternate, ovate-lanceolate, margins smooth. At the tenth leaf stage: leaf blade deeply lobed (7-9 lobes) with the divisions almost extending to the midrib. Midrib raised on the upper surface. Crushed leaves emit a fetid odour. Leaves sparsely clothed in very small hairs on the upper surface but the lower surface densely clothed in stellate, pale hairs. Spines usually present on the stem, petiole and midrib on the upper surface of the leaf blade.
Distribution and Ecology
The closed forest form of S. quadriloculatum occurs in NEQ. Altitudinal range from 400-900 m. Grows in disturbed areas in rain forest particularly those with Kauri Pine (Agathis robusta) monsoon forest and vine thickets. Further work is needed to check the application of the name S. quadriloculatum to this taxon.
The fruits of this species are poisonous to sheep. Everist (1974).
