The Ant Orchid is a fairly small West Australian orchid with yellowish or greenish lateral sepals and petals which have a reddish band down the centre. The narrow red and green striped petals and sepals give it the alternate common name of Clown Orchid. The labellum or lip is broad and greenish with reddish black bumps or warts (calli) down the centre that would appear to be the origin of the name Ant Orchid. Flowers are borne on straight stems to about 30 cm tall and are produced in spring from August to September. Individual flowers are about 3 cm across. It produces narrow hairy grass like leaf from the base of the plant.

woodland, mallee country

Caladenia roei is found in the south west of Western Australia roughly in an area west of Kalgoorlie, north of Esperance and south of Shark Bay.
