Description

Eriochilus cucullatus is a terrestrial, perennial, deciduous, herb with an underground tuber. It has a single, egg-shaped, bright shiny green, glabrous leaf which is not fully developed until after flowering, when it is 15–35 mm (0.6–1 in) long and 7–12 mm (0.3–0.5 in) wide. One or two bright pink to magenta flowers are borne on a slender spike, 100–250 mm (4–10 in) tall. The dorsal sepal is spoon-shaped to lance-shaped with the narrower end towards its base and 5–8 mm (0.2–0.3 in) long. The lateral sepals are 5–8 mm (0.2–0.3 in) long and turn downwards and away from each other. The petals are pink, linear in shape, 6–7 mm (0.2–0.3 in) long, erect and held near the column. The labellum is green or yellowish near its base, pinkish near the tip and has three lobes, the middle one egg-shaped and 2–3 mm (0.08–0.1 in) wide with small clusters of reddish bristles. Flowering occurs from December to March.[2][3]

Taxonomy and naming
