Caladenia roei (Caladenia roei)
Description
Caladenia roei is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 60–150 mm (2–6 in) long and about 5 mm (0.2 in) wide. Up to three greenish-yellow and red flowers 30–40 mm (1–2 in) long, 20–30 mm (0.8–1 in) wide are borne on a stalk 120–300 mm (5–10 in) tall. The sepals have thick, yellowish-brown, club-like glandular ends 3–4 mm (0.1–0.2 in) long. The dorsal sepal is erect, 15–20 mm (0.6–0.8 in) long, about 2 mm (0.08 in) wide and often curves gently forward. The lateral sepals and petals are about the same size as the dorsal sepal and turn obliquely downward and form a crucifix-like shape. The labellum is 8–11 mm (0.3–0.4 in) long, 13–16 mm (0.5–0.6 in) wide and greenish-yellow with a small red tip which curls under. The sides of the labellum are smooth, lacking teeth but there is a dense band of dark reddish-purple, calli up to 1.5 mm (0.06 in) long, in the middle of the labellum. Flowering occurs from August to October.
