It also resembles the winter donkey orchid (Diuris brumalis) but flowers later than that species.

It is one of the most common orchid species in the Perth area, often forming extensive colonies and usually having numerous flowers on the one spike.

[2][3] Diuris corymbosa was first formally described in 1840 by John Lindley and the description was published in A Sketch of the Vegetation of the Swan River Colony as an appendix to Edwards's Botanical Register.

[3] The Common donkey orchid occurs between Dongara and Albany where it grows in woodland, often on the margins of swamps.

Diuris corymbosa is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
