Caladenia audasii

Description

Caladenia audasii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf, 5–10 cm (2–4 in) long and 6–10 mm (0.2–0.4 in) wide. A single yellow flower 9 cm (4 in) in diameter is borne on a spike 11–19 cm (4–7 in) high. The petals and sepals are 3–6 cm (1–2 in) long and spreading, the petals somewhat shorter than the sepals. The petals and lateral sepals are 4–5 mm (0.16–0.20 in) wide and taper to a thread-like end covered with glandular hairs. The labellum is curved with the tip rolled under and has erect lateral lobes. It is about 18 mm (0.7 in) long and 10 mm (0.4 in) wide when flattened. The edges of the labellum are scalloped and the middle lobe has short, broad teeth. There are six rows of stalkless calli along the centre of the labellum. Flowering occurs from September to November.
