Description
Acianthus sinclairii is a terrestrial, perennial, deciduous, sympodial herb with a single heart-shaped, glabrous, dark green leaf which often has a maroon tinge or markings. The leaf is long, one-quarter to halfway up the slender stem, which is about long at flowering but increases later.There are up to ten flowers, long, green but with purple blotches and a dull red labellum. The dorsal sepal is broadly lance-shaped to egg-shaped and forms a hood over the column. The lateral sepals are similar in length to the dorsal sepal but have a pointed end and face forward beneath the labellum. The petals are somewhat shorter than the sepals, are lance-shaped and spread widely. The labellum is also shorter than the sepals, dished, broadly egg-shaped with the edges turned under, dull red with two rounded calli at its base. Flowering occurs between January and October.
