The species has previously been known as Malaxis acuminata which occurs in Southeast Asia but has been shown to be genetically and morphologically distinct from that species.

Distribution and habitat

The yellow spur orchid grows in moist areas, especially near springs in dense rainforest and is found in northern parts of the Northern Territory including Bathurst Island.
