Description

Grey-green downy forb to 0.3 m high, densely covered with pale star-shaped hairs. Firm pale spines to 15 mm long are scattered along the stems. Leaves rounded, 1.5-3 cm long, 1-2 cm wide, shallowly lobed along the edges, densely hairy. Flowers purple, shallowly bell-shaped, 20-35 mm in diameter. Berry about 7 mm in diameter.

Distribution

Menindee Nightshade is the only species of Solanum endemic to NSW and is restricted to the far south-western plains, extending up the Darling River to the Menindee and Wilcannia districts. Mainly restricted to the area between the Darling and Lachlan Rivers. Localities include Kars Station, Lake Tandou, Lake Cawndilla, Oxley area, between Broken Hill and Menindee, and the Darling River. It has been recorded from Kinchega National Park and Nearie Lake Nature Reserve.

Habitat and ecology

  • Grows in occasionally flooded depressions with heavy soil, including level river floodplains of grey clay with Black Box and Old Man Saltbush, and open treeless plains with solonized brown soils.
  • Habitats are generally lake beds or floodplains of heavy grey clays with a highly self-mulching surface. Also found on sandy floodplains and ridges and in calcareous soils, red sands, red-brown earths and loamy soils.
  • Flowers chiefly in spring.
  • Has been observed in the field to have an extensive root system which will grow when cut and left on the soil surface. This species is ephemeral in nature, appearing following rainfall events. It also tolerates disturbance and will often appear after such activities as grading, ploughing and flooding for irrigation.
  • Menindee Nightshade is a clonal species and is recorded as common to locally abundant in most populations. It can form small colonies of several hundred plants, to large spreading colonies found over an area of 8-12000 hectares (11 stands over about 6 km). Isolated and few plants have also been recorded at some sites.
