Taxonomy

Chiloglottis sphaerula was first formally described in 2006 by David Jones from a specimen collected in the Barrington Tops National Park and the description was published in Australian Orchid Research.[2] The specific epithet (sphaerula) is a Latin word meaning "ball"[3] referring to the shape of the "head" of the insect-like callus.[1]

This species was formerly known as Chiloglottis sp. aff. sphyrnoides (Northern Tablelands).[1][4]

Distribution and habitat

This orchid grows in tall, moist forest on the southern part of the Northern Tablelands and Barrington Tops National Park.[1][4]
