Description

Habenaria vatia is a tuberous, perennial herb with between three and five upright leaves, 60–100 mm (2–4 in) long, and 10–18 mm (0.4–0.7 in) wide. Between fifteen and twenty five white flowers, 10–12 mm (0.39–0.47 in) long and 15–17 mm (0.59–0.67 in) wide, are borne on a flowering stem 300–500 mm (10–20 in) tall. The dorsal sepal is about 4 mm (0.2 in) long, 3 mm (0.1 in) wide and, with the petals, forms a hood over the column. The lateral sepals are about 5 mm (0.2 in) long, 2 mm (0.08 in) wide, and spread apart from each other, and the petals are a similar size to the sepals. The labellum is shaped like a trident and has three lobes about 8 mm (0.3 in) long and 1.5 mm (0.06 in) wide. The nectary spur is green with a white base, 12–14 mm (0.47–0.55 in) long and about 2 mm (0.08 in) wide. Flowering occurs from December to January. [2]

Taxonomy and naming

Habenaria vatia was first formally described in 2002 by David Jones, but the name was not validly published. [3] In 2015, Michael Mathieson validated the name and description. [4] [5] The specific epithet (vatia) is a Latin word meaning "bent outward" or "bowlegged". [6]

Distribution and habitat

The curved rein orchid grows with grasses and low shrubs in woodland on Moa Island and other Torres Strait Islands. [2] [5]

Conservation

Habenaria vatia is listed as "vulnerable" under the Queensland Nature Conservation Act 1992. [5]
