Scientific name: Euphrasia bowdeniae
Conservation status in NSW: Vulnerable
Commonwealth status: Vulnerable
Profile last updated: 17 Aug 2021


A semi-parasitic perennial herb to approx. 22 cm high. Rootlets may be connected to those of other plants. Stems are often reddish with two rows of hairs. Glossy green to reddish leaves 4 - 7.5 mm long and up to 3.2 mm wide, with tubular mauve to violet flowers 7 - 10.5 mm long.


Endemic to the upper Blue Mountains.

Habitat and ecology

  • Confined to wet or damp vertical sandstone rock faces on major cliff-lines facing south or east, growing in small pockets of damp, sandy soil on ledges or at the cliff base. May also occur in damp sites at the top of cliffs. The rock faces receive seepage moisture and support a range of heath plants, particularly epacrids and ferns.
  • Sites are associated with the Hassans Walls soil landscape with steep Narrabeen Sandstone cliffs colluvial talus slopes developed over Illawarra Coal Measures. Altitude varies between 600-750 m.
  • Flowering has been recorded from September to December, with fruits from early December. Old flower heads and fruits have been observed as late as April. Seeds are small and dispersal is likely to be localised and close to the parent plant, with seed accumulating on ledges, in soil pockets or at the base of the rock face. However storage of the seed in the soil seedbank is likely to be limited by the availability of soil, with minimal soil accumulation and development in the rocky sites where this species is found.
  • Likely to be fire sensitive, and lacking in specialised fire-response strategies.
