Description

Eriochilus valens is a terrestrial, perennial, deciduous, herb with an underground tuber and a single egg-shaped leaf 5–20 mm (0.2–0.8 in) long and 5–10 mm (0.2–0.4 in) wide. The leaf is held above the ground on a thin stalk 20–50 mm (0.8–2 in) high. Up to four white or pink flowers about 10 mm (0.4 in) long and wide are borne on a stem, 10–250 mm (0.4–10 in) tall. The dorsal sepal is egg-shaped with the narrower end towards the base, 6–8 mm (0.2–0.3 in) long and 2–3 mm (0.08–0.1 in) wide. The lateral sepals are 9–11 mm (0.35–0.43 in) long, 3–4 mm (0.1–0.2 in) wide and spread forwards. The petals are narrow spatula-shaped 5–7 mm (0.2–0.3 in) long, about 1 mm (0.04 in) wide and are held close to the dorsal sepal. The labellum is pink to red, 6–8 mm (0.2–0.3 in) long, about 3 mm (0.1 in) wide and has three lobes. The middle lobe is 2.5–3.5 mm (0.098–0.14 in) long and is fleshy with red bristles. Flowering occurs from March to May but is much more prolific after fire the previous summer. [2] [3] [4] [5]

Taxonomy and naming

Eriochilus valens was first formally described in 2006 by Stephen Hopper and Andrew Brown from a specimen collected in the Bakers Junction Nature Reserve north of Albany and the description was published in Nuytsia . [6] The specific epithet (valens) is a Latin word meaning "strong" or "vigorous", [7] referring to the large labellum of this orchid. [4]

Distribution and habitat

The red-lipped bunny orchid grows in woodland and shrubland around winter-wet swamps, mainly between Walpole and Albany. [3] [4] [5] [8]

Conservation

Eriochilus valens is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [8]
