Description

Pterostylis - the greenhoods - is a large genus of ground-dwelling orchids with mostly green flowers. The flower is characterised by a ‘hood’ comprising a sepal and two petals, which covers the rest of the flower to force pollinators past the sexual organs. The Waterfall Greenhood has three to five oval-shaped leaves at the base of the single 15 cm tall flower-stem. The stem bears a single large flower and up to five stem-leaves. The flower is white with green stripes and is rusty towards the tip. The labellum (the internal ‘lip petal’) is just visible at the flower opening; it is broad and notched at the tip.

Distribution

The Waterfall Greenhood is found only at Fitzroy Falls, Belmore Falls, upper Bundanoon Creek (Meryla) and Minnamurra Falls.

Habitat and ecology

  • The Waterfall Greenhood is found on cliff faces close to waterfalls and creek banks and mossy rocks alongside running water.
