Pterostylis angulata is a small terrestrial greenhood orchid from south-western Western Australia, grown mainly by native plant enthusiasts rather than as a common garden or houseplant. It grows from a tuber and is best cared for by reproducing its natural habitat of moist, seasonally wet woodland and heath.
Pterostylis angulata, commonly known as the Helena River snail orchid or limestone snail orchid, is a species of greenhood orchid endemic to south-western Australia.
Pterostylis angulata is restricted to south-western Western Australia, with a somewhat coastal distribution ranging between Perth in the north and Bunbury in the south, reaching as far east as York and Collie. It is common within this range, which includes a number of reserves and national parks, though populations in some locations have declined due to fires and soil disturbance. It can be found in a variety of habitats including woodlands, swamps, and coastal forests and heaths. It tolerates a range of soil conditions, from sandy soils to heavy clay loams.
