|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is scattered and locally abundant in dry sclerophyll forest on flat plateau country on sandstone.|
|Generation Length (years):||60|
|Major Threat(s):||This species has been affected by habitat loss, with estimates for decline of 10-20% in the past 50 years. However, there appears to be no recruitment and pollination does not seem to be taking place. The future decline is therefore estimated to >30% over three generations.|
