Prasophyllum lindleyanum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single smooth, tube-shaped leaf up to 300 mm (10 in) long and 3–5 mm (0.1–0.2 in) in diameter near the base.

The labellum is white, often with a pink tinge, 5–8 mm (0.2–0.3 in) long and slightly crinkled with a central, greenish callus.

Flowering occurs from September to January and is more prolific after fire the previous summer.

[1][2] Prasophyllum lindleyanum was first formally described in 1871 by Heinrich Reichenbach and the description was published in Beitrage zur Systematischen Pflanzenkunde.

[3][4] The specific epithet (lindleyanum) honours John Lindley who died a few years before.
