Caladenia horistes (Caladenia horistes)
Description
Caladenia horistes is a terrestrial, perennial, deciduous, herb with an underground tuber and a single erect, hairy leaf, 40–160 mm (2–6 in) long and 3–7 mm (0.1–0.3 in) wide. One or two flowers 50–80 mm (2–3 in) long and 40–60 mm (1.6–2.4 in) wide are borne on a stalk 140–250 mm (6–10 in) tall. The flowers are cream-coloured to creamy-yellow and the sepals and petals spread horizontally but have long, drooping, dark, thread-like tips. The dorsal sepal is erect, 45–90 mm (2–4 in) long and 2–3 mm (0.08–0.1 in) wide at the base and the lateral sepals are about the same size. The petals are 40–80 mm (2–3 in) long and about 3 mm (0.1 in) wide. The labellum is 12–16 mm (0.5–0.6 in) long and 10–13 mm (0.4–0.5 in) wide and a similar colour to the sepals and petals but with pale brown or red lines and blotches. The sides of the labellum have short teeth, the tip is turned downwards and there are two rows of cream to yellowish, anvil-shaped calli along its centre. Flowering occurs from August to early October.
