This greenhood usually has a white and reddish-brown striped flower with a long, curved labellum and is found along the south coast between Binningup and Esperance.

The lateral sepals are erect with a small gap between them and the galea and thread-like ends 20–25 mm (0.8–1 in) long.

[3][4][5] Pterostylis rogersii was first formally described in 1930 by Edith Coleman and the description was published in The Victorian Naturalist from specimens collected between Bunbury and Collie.

[1][6] The specific epithet (rogersii) honours Richard Rogers "because the new species is abundant and beautiful".

[3][4][5][7] Pterostylis rogersii is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
