About Caladenia infundibularis A.S.George
Caladenia infundibularis A.S.George is a terrestrial, perennial, deciduous herb that grows from an underground tuber. It produces a single hairy leaf, 80 to 120 millimeters (3 to 5 inches) long and approximately 12 millimeters (0.5 inches) wide. Between one and three greenish-yellow flowers, each 80–120 millimeters (3–5 inches) long and 60–80 millimeters (2–3 inches) wide, are borne on a stalk that grows 250–450 millimeters (10–20 inches) tall. The dorsal sepal of the flower is erect, measuring 35–55 millimeters (1–2 inches) long and 2–3 millimeters (0.08–0.1 inches) wide. The lateral sepals are 35–65 millimeters (1–3 inches) long and 4–6 millimeters (0.16–0.24 inches) wide, with thin, yellowish-brown, club-like glandular tips 6–15 millimeters (0.2–0.6 inches) in length. The petals are 27–38 millimeters (1.1–1.5 inches) long and 3–8 millimeters (0.1–0.3 inches) wide, spreading widely or curving slightly downwards. The labellum is greenish-yellow with a red tip, 20–24 millimeters (0.8–0.9 inches) long and 11–16 millimeters (0.4–0.6 inches) wide, with a downward-pointing tip. The tip of the labellum is funnel-shaped, with many spreading teeth up to 5 millimeters (0.2 inches) long along its sides, and four or six rows of yellowish calli along its midline. Flowering of this species takes place in October and November. Commonly called the funnel-web spider orchid, Caladenia infundibularis grows in coastal heath, forest, and woodland. It is found between Dunsborough and Northcliffe in Western Australia's Jarrah Forest, Swan Coastal Plain, and Warren biogeographic regions.
