Labellum wholly purplish, extending c. 5 mm beyond dorsal sepal, tubular with incurved lateral margins and flared apex, inflated in middle, orifice directed downwards and forwards, margins entire or almost so; auricles short, tubular, opening at apex; calli brush-like, extending in a single row from orifice to base along middle of lamina.

A variant from the Anglesea area (growing in wet heathland) with a brighter reddish flower, a smaller dorsal sepal, often spathulate petals and a ribbed (underneath) labellum requires further investigation.
