Pheladenia deformis, commonly known as blue fairy orchid or blue beard is the only species of the flowering plant genus Pheladenia in the orchid family, Orchidaceae and is endemic to Australia. It was originally named as Caladenia deformis and has since had several name changes. Plants have a single, narrow, hairy leaf and usually blue flowers with relatively short, broad sepals and petals and an unusual labellum.thumb|225px|Pheladenia deformis labellum detail

Praecoxanthus aphyllus, commonly known as leafless orchid, is the only species of the flowering plant genus Praecoxanthus in the orchid family, Orchidaceae and is endemic to the south-west of Western Australia. Plants in flower lack a true leaf, although those plants that are not flowering do possess a green leaf. This species is one of the first orchids to flower each year and its creamy white, fragrant flower easily distinguishes it from other species.
