Caladenia alata, commonly known as the fairy orchid, is a plant in the orchid family Orchidaceae and is found in south-eastern Australia and New Zealand. It is a ground orchid with small, usually short-lived flowers, which have relatively stiffly held petals and sepals and reddish-purple bars on the labellum.
Description
Caladenia alata is a terrestrial, perennial, deciduous, herb, usually solitary but sometimes in groups of up to twenty individuals. It has an underground tuber and a single, sparsely hairy, linear to narrow lance-shaped leaf, 3–13 cm (1–5 in) long, 1–3 mm (0.04–0.1 in) wide and dark to reddish green.
One or two short-lived flowers 10–15 mm (0.4–0.6 in) in diameter are borne on a thin, wiry spike up to 8–24 cm (3–9 in) high. The dorsal sepal is erect, about the same length or slightly shorter than the lateral sepals, and narrow elliptic in shape. The lateral sepals and petals are 3–11 mm (0.1–0.4 in) long, white or pink, asymmetrically egg-shaped with narrowing tips that are slightly hooked. The labellum is 5–6 mm (0.20–0.24 in) long when flattened, has three lobes and is white or pink with purple bars and a down-curved, yellow tip. The lateral lobes are large and broad with a smooth edge. There are two rows of stalked, club-shaped, yellow calli on the mid-lobe. Flowering occurs from August to October.
