About Caladenia quadrifaria (R.S.Rogers) D.L.Jones
Caladenia quadrifaria, commonly called the large pink fingers orchid, is a terrestrial, perennial, deciduous herb with an underground tuber. It produces a single, sparsely hairy linear leaf that measures 70 to 150 mm (3 to 6 in) long and 3 to 4 mm (0.1 to 0.2 in) wide. Up to three pale pink to bright pink flowers grow on a 100–200 mm (4–8 in) tall spike. The backs of the flowers are greenish-pink or brownish pink, and covered with many glandular hairs. The dorsal sepal is 15–20 mm (0.6–0.8 in) long and 3–4 mm (0.1–0.2 in) wide, while the lateral sepals are 15–20 mm (0.6–0.8 in) long and 5–6 mm (0.20–0.24 in) wide. The petals are 15–20 mm (0.6–0.8 in) long and 4–5 mm (0.16–0.20 in) wide, and spread fan-like alongside the lateral sepals. The labellum measures 7–9 mm (0.3–0.4 in) in both length and width, and is pink with reddish bars. The sides of the labellum curve upward, and its tip curls under. There are four to eight long teeth on each side of the labellum near the tip, and four to six rows of large, club-shaped calli along the labellum's mid-line. Flowering takes place from August to November. This orchid is found in coastal New South Wales, Australia, between Brunswick Heads and Lake Tabourie, where it grows in forest on slopes and ridges.
