Solanum cinereum

Solanum cinereum is a nightshade, known by the common name Narrawa burr. It is native to open woodland in south eastern Australia.

S. cinereum is a small perennial shrub, either sprawling, or erect to 1 meter. The leaves are heavily lobed, dark green, and shiny, and have sharp spines (~1 cm) over the surface of the leaf, and along the major veins. The flowers are purple, and occur all year, but less often in winter. The fruit is like a small, hard tomato up to about 2 cm in diameter, and coloured yellow, green, and drying to black.

S. cinereum is considered a weed in farmland, because it is poisonous to sheep, cattle, and possibly horses.
