Description

Caladenia amoena is a terrestrial, perennial, deciduous, herb with an underground tuber and a single, densely hairy, lance-shaped leaf, 3–8 cm (1–3 in) long and 7–9 mm (0.3–0.4 in) wide which often has purplish blotches near its base. A single flower (rarely two) is borne on a spike 5–12 cm (2–5 in) high. The dorsal sepal is erect, linear to narrow lance-shaped, 20–25 mm (0.8–1 in) long and about 3 mm (0.1 in) wide. It is narrower near the end which terminates in a glandular structure about 2 mm (0.08 in) long. The lateral sepals are oblong to lance-shaped, 17–23 mm (0.7–0.9 in) long, about 3.5–5 mm (0.1–0.2 in) wide and end in a gland similar to the one on the dorsal sepal. The petals are 15–18 mm (0.6–0.7 in) long and taper to a point. The labellum is heart-shaped, curves forward, 9–12 mm (0.4–0.5 in) long and 8–11 mm (0.3–0.4 in) wide when flattened. The labellum has three yellowish-green lobes, reddish in the central part, the middle lobe with about 7 pairs of broad teeth. The lateral lobes are also toothed near the mid-lobe. There are four rows of foot-shaped calli which are reddish and about 3 mm (0.1 in) at the back of the labellum, decreasing in size towards the front. The column is 8–9 mm (0.3–0.4 in) long and has reddish markings. Flowering occurs from August to October. Caladenia amoena is similar to C. concinna but has smaller flowers and somewhat drooping petals and sepals.
