About Caladenia corynephora A.S.George
Caladenia corynephora A.S.George is a terrestrial, perennial, deciduous herb. It grows from an underground tuber and produces a single erect, hairy leaf that is 15–20 cm (6–8 in) long and 8–10 mm (0.3–0.4 in) wide. One or two flowers, each 6–7 cm (2–3 in) long and 4–6 cm (1.6–2.4 in) wide, are borne on a flowering spike 25–45 cm (10–20 in) high. The dorsal sepal of the flower is erect, while the lateral sepals and petals are downswept. All these structures are greenish-yellow with red stripes along their centres, and their tips are covered in glandular hairs. The labellum is greenish-yellow with a club-shaped, red tip, edged with a fringe of very long, narrow segments. Four or more rows of red calli run along the centre line of the labellum. Flowering occurs between late November and early February. This species, commonly called the club-lipped spider orchid, grows in winter-wet swamps, granite outcrops, and karri forest. It is found between Albany and Margaret River in Western Australia, within the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions.
