It is a ground orchid with a single, sparsely hairy leaf, and up to three bright pink flowers with the central part of the labellum completely covered with black calli. It is a widespread species but not common in any part of its range.

Caladenia flava subsp. maculata, commonly known as the Kalbarri cowslip orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single, hairy leaf and up to three lemon-yellow flowers with brownish-fawn spots on some parts. It mainly occurs in near-coastal areas north of Geraldton.
Caladenia fragrantissima, commonly known as the scented spider orchid, is a plant in the orchid family Orchidaceae and is endemic to Victoria and South Australia. It is a ground orchid with a single hairy leaf and up to three creamy-white to yellowish-green flowers. It is possible that it is conspecific with Caladenia orientalis.

Glossodia minor, 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.
Pterostylis squamata, commonly known as the southern rustyhood or ruddyhood, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. Flowering plants have up to ten translucent green flowers with reddish-brown markings and a hairy, insect-like labellum. Non-flowering plants have a rosette of four to eight egg-shaped leaves. This species is very similar to Pterostylis rufa which has a narrower labellum and other minor differences.
Acianthus caudatus, commonly known as mayfly orchid, is a species of flowering plant in the orchid family Orchidaceae and is endemic to eastern Australia. It is a terrestrial herb with a single egg-shaped or heart-shaped leaf and up to nine dark purplish flowers with thin, spreading sepals and petals, often with a musty odour.
