Update on generic and specific nomenclature in Paracaleana (Drakaeinae), Caladeniinae and a new name in Caladenia (Orchidaceae)
HOPPER, STEPHEN D. AND BROWN, A.P.
Accepting guidance on stability of names from the Preamble to successive International Codes of Botanical Nomenclature, and in the interests of minimizing name changes consistent with present scientific evidence, we propose that the Australian orchid genus Paracaleana should be maintained as a distinct genus from Caleana, and that Caladenia remains best recognised as distinct from Cyanicula, Ericksonella, Pheladenia, Glossodia and Elythranthera. Recent proposals to lump these genera unnecessarily creates new names in the absence of compelling new scientific evidence to do so. A new name, Caladenia varians Hopper & A.P.Br., is erected to replace C. vulgata Hopper & A.P.Br. The type of C. vulgata matches Caladenia incensum Hopper & A.P.Br., and the former species is therefore rendered synonymous with the latter.
