Description
Orchids in the genus Cyrtostylis are terrestrial,
Orchids in this genus are similar to those in Acianthus but lack the long appendage on the ends of the sepals and petals of that genus. The lateral sepals differ from the petals in Acianthus.
Taxonomy and naming
The genus was first formally described in 1810 by
The name Cyrtostylis is derived from the Greek words cyrtos meaning 'curved' and stylos, 'pertaining to the style', referring to the curved column found in all members of this genus.[8]
The World Checklist of Selected Plant Families lists five species of Cyrtostlyis but Australian authorities list six. The difference lies in the interpretation of Cyrtostylis huegelii[2][8][9][10] which the Checklist considers a synonym of Cyrtostylis reniformis var. huegelii.[11]
