Caladenia × cala is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, 180–200 mm (7–8 in) long and 9–15 mm (0.4–0.6 in) wide. One or two red and white or red and pale greenish flowers 60–80 mm (2–3 in) wide are borne on a spike 200–400 mm (8–20 in) tall. The lateralsepals often curve upwards and the labellum is white with a red tip, a long fringe on the sides and four or more rows of calli along its mid-line. Flowering occurs in September and October.[2][3]
Taxonomy and naming
Caladenia × cala was first formally described in 2001 by Hopper and Andrew Brown from a specimen collected near Bullaring. The description was published in Nuytsia.[4][5] The epithet (cala) is derived from the Greek word kalos meaning "beautiful",[6] referring to the flowers of this orchid.[3]
