It has a single tubular leaf and up to twenty five reddish-brown flowers and only occurs in a few locations at higher altitudes.

The lateral sepals are linear to lance-shaped, about 7 mm (0.3 in) long, free from and parallel to each other.

There is a raised, shiny callus in the centre of the labellum and extending almost to its tip.

[6] Prasophyllum rogersii was first formally described in 1928 by Herman Rupp and the description was published in Proceedings of the Linnean Society of New South Wales.

[1][7] The specific epithet (rogersii) honours Richard Sanders Rogers whom Rupp described as "our recognized leader in the field of Australian orchidology".
