Caladenia postea (Caladenia postea)
Description
Caladenia postea is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 70–100 mm (3–4 in) long and 3–7 mm (0.1–0.3 in) wide. Up to three pale creamy white flowers with red markings and 60–70 mm (2–3 in) long, 40–50 mm (1.6–2.0 in) wide are borne on a stalk 160–200 mm (6–8 in) tall. The sepals and petals have long, thin, brown, thread-like ends. The dorsal sepal is erect, 40–55 mm (1.6–2.2 in) long and about 2 mm (0.08 in) wide. The lateral sepals are about the same size as the dorsal sepal, held horizontally near their bases then turn downwards and droop. The petals are 35–45 mm (1–2 in) long, 2–3 mm (0.08–0.1 in) wide and arranged like the lateral sepals. The labellum is 8–14 mm (0.3–0.6 in) long, 7–9 mm (0.3–0.4 in) wide and creamy-white with pale red lines and spots. The sides of the labellum have short, blunt teeth and the tip is curled under. There are two rows of anvil-shaped, cream-coloured calli along the mid-line of the labellum. Flowering occurs from October to November.
