Labellum on a short claw, trullate, 5–6 mm long, pinkish, recurved at right angle near middle, the lower margins incurved and smooth, upper margins crenulate; callus plate brown or green, much raised at the bend, channelled below, apex blunt and short, often wrinkled.

EGU, HNF, MonT, SnM. Apparently confined to sub-alpine meadows and fertile montane woodland in the Mt Cobberas region of eastern Victoria.

Very similar to Prasophyllum frenchii, but differs in its later flowering, sub-alpine habitat, fewer and sparser flowers, the crenulate labellum and the less wrinkled callus.

The name P. rogersii has been misapplied to P. niphopedium and P. litorale in Victoria.
