Genus of orchids
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.
In 1888, Robert Fitzgerald formally described "Corunastylis apostasioides" and published the description in "Australian Orchids", the first time the name "Corunastylis" had been used. In 1889, Ferdinand von Mueller changed the name to "Prasophyllum apostasioides" and in 1989, David Jones and Mark Clements placed it and most other species of "Prasophyllum" into "Genoplesium". In 2002 Jones and Clements moved all the species of "Genoplesium" back into "Corunastylis" except for the New South Wales species "Genoplesium baueri".
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.
Plants of the World Online considers "Corunastylis" to be a synonym of "Genoplesium". 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" and "P. unicum" respectively.
The genus name "Corunastylis" is derived from Greek words meaning "a thick stick" and "a style".
