With the name of Wild Tomato (Solanum quadriloculatum), this particular Solanum is very poisonous and should not be consumed. It is often mistaken for S. ellipticum.

Solanum quadriloculatum is a semi-erect small shrub like plant that grows up to 40 cm high. The leaves are a soft grey-green colour, almost woolly with white hairs, as well as long purplish-black spines. The fruit is angular and spongy when green, becoming light yellow-brown and hard when ripe, drying out to a bone-like texture.

Extreme care should be taken as the Solanum quadriloculatum is often found growing among edible species and often mistaken for Solanum ellipticum.

Whilst the species is considered to be widespread in arid regions, it has been noted that some publication give the distribution as northern Australia.

CAUTION
There are many Solanum species that resemble Solanum centrale, and only some of them produce edible fruit. Some closely related species produce fruit that are toxic.

The unripe fruit contains the toxin solanine (the same as that found in green potatoes) and must be fully ripened before consumption.

S. sturtianum is poisonous and can usually be recognised by the yellow or black dry brittle fruits.
