Corunastylis is a historically recognized genus of about 50 species of orchids, native to Australia and New Zealand, now included in the genera Genoplesium and Prasophyllum.
[4] A recent phylogenetic analysis of Prasophyllinae suggests that Corunastylis is paraphyletic, and funding from The Australian Orchid Foundation is supporting field work and molecular studies to improve understanding of the phylogeny of the subtribe.
[5] Plants of the World Online considers Corunastylis to be a synonym of Genoplesium.
[6] All the species in the list below are now considered to be included in Genoplesium, except for Corunastylis obovata and Corunastylis unica, now included in the genus Prasophyllum as P. obovatum[7] and P. unicum[8] respectively.
The genus name Corunastylis is derived from Greek words meaning "a thick stick" and "a style".
