Caladenia campbellii (Caladenia campbellii)
Description
Caladenia campbellii is a terrestrial, perennial, deciduous, herb which grows singly or in small groups. It has an underground tuber and a single, sparsely hairy, narrow linear, dark green leaf, 4–9 cm (2–4 in) long and 2–3 mm (0.08–0.1 in) wide. There are one or two flowers 15–18 mm (0.6–0.7 in) in diameter borne on a fairly thick (about 1.5 mm (0.06 in)), sparsely hairy spike 8–14 cm (3–6 in) high. The dorsal sepal is 8–10 mm (0.3–0.4 in) long, about 3 mm (0.1 in) wide and oblong to narrow egg-shaped. The lateral sepals and petals are lance-shaped, 8–11 mm (0.3–0.4 in) long, about 3 mm (0.1 in) wide, cream-coloured on the inside and pinkish on the outside. The labellum is about 6 mm (0.2 in) long and 6–7 mm (0.2–0.3 in) wide and cream-coloured with reddish lines and a yellowish tip. It has three distinct lobes and is erect near its base then more or less horizontal with the tip curving downwards. The lateral lobes are about 2.5 mm (0.1 in) wide and more or less erect. The mid-lobe is narrow egg-shaped, about 2.5 mm (0.1 in) long, 2 mm (0.08 in) wide with one broad pair of teeth on its edges. There are two rows of yellow to orange calli with white stalks in the centre of the labellum. The column is 5–6.5 mm (0.2–0.3 in) long and curves forward near its end. Flowering occurs over a very short period about the first two weeks of November but the flowers are only open for a day or two before self-pollinating.
