Description

Austral Toadflax is a small, straggling herb to 40 cm tall. Leaves are pale green to yellow-green, somewhat succulent, 1 - 4 cm long and 0.5 - 1.5 mm wide. Flowers are minute and white, emerging where the leaves meet the stems and appearing in spring. The fruit is small and nut-like, developing in summer. This species is often hidden amongst grasses and herbs.

Distribution

Austral Toad-flax is found in very small populations scattered across eastern NSW, along the coast, and from the Northern to Southern Tablelands. It is also found in Tasmania and Queensland and in eastern Asia. Although originally described from material collected in the SW Sydney area, populations have not been seen in a long time. It may persist in some areas in the broader region.

Habitat and ecology

  • Occurs in grassland on coastal headlands or grassland and grassy woodland away from the coast.
  • Often found in association with Kangaroo Grass (Themeda australis).
  • A root parasite that takes water and some nutrient from other plants, especially Kangaroo Grass.
