Pterostylis sanguinea is widespread inland from north of Kalbarri to Balladonia and east to South Australia. They have up to 10 flowers that are held up to 30cm high between June and September.

Pterostylis comes from the Greek words pteron, meaning wing, and stylos, meaning pillar, referring to the winged column. The column is an organ combining the stamens and style of the flower. Sanguinea is from the Latin word sanguineus, meaning blood-coloured, of both fresh and dried blood.
