It contained two species and a named hybrid, all endemic to the south-west of Western Australia. The genus was first formally described in 1963 by the Australian botanist Alex George who published his description in Western Australian Naturalist. Orchids in the genus Elythranthera had previously been included in Glossodia section Elythranthera.

Caladenia major, commonly known as the waxlip orchid, parson-in-the-pulpit, or purple cockatoo is a plant in the orchid family Orchidaceae, and is endemic to Australia. It is a ground orchid with a single hairy leaf and one or two purple to mauve flowers. It has been known as Glossodia major since its description by the prolific Scottish botanist Robert Brown in 1810, but recent discoveries suggest its inclusion in the genus Caladenia.
Caladenia minorata, commonly known as the small waxlip orchid, is a plant in the orchid family Orchidaceae and is endemic to eastern Australia. It is a ground orchid with a single very hairy leaf and one or two deep violet-blue flowers. It has been known as Glossodia minor since its description by the prolific Scottish botanist Robert Brown in 1810, but recent discoveries suggest its inclusion in the genus Caladenia. It is similar to Caladenia major but is smaller in all its parts.
Caladenia strigosa is a plant in the orchid family Orchidaceae and is endemic to South Australia. It is a ground orchid with a single leaf and a single greenish-cream flower with fine reddish streaks. It grows in sandy soil in shrubland.
