Description
Caladenia mesocera is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 40–80 mm (2–3 in) long and 4–10 mm (0.2–0.4 in) wide. Usually only one greenish-yellow and red flower 30–40 mm (1–2 in) long and 20–30 mm (0.8–1 in) wide is borne on a stalk 80–250 mm (3–10 in) tall. The dorsal sepal is bent backwards, 20–30 mm (0.8–1 in) long and 2–3 mm (0.08–0.1 in) wide. The lateral sepals are 18–25 mm (0.7–1 in) long, 2.5–6 mm (0.1–0.2 in) wide and spread widely. The petals are 15–24 mm (0.6–0.9 in) long and about 2 mm (0.08 in) wide and downswept. The labellum is 10–15 mm (0.4–0.6 in) long and 3–7 mm (0.1–0.3 in) wide, insect-like and stiffly hinged. It is densely hairy, greenish-yellow and red with a "false head" 2–3 mm (0.08–0.1 in) across at its highest point and there is a horn-like gland 2 mm (0.08 in) long either side of the "head". Flowering occurs from August to early October.
