Gastrodia lacista, commonly known as the western potato orchid,[2] is a leafless terrestrial mycotrophic orchid in the family Orchidaceae. It has a thin brown flowering stem with up to fifty small, drooping, fawn and white, tube-shaped flowers. It grows in forest and woodland in the south-west of Western Australia. DescriptionGastrodia lacista is a leafless terrestrial, mycotrophic herb that has a thin, brown crook-like flowering stem bearing between five and fifty drooping, fawn and white, tube-shaped flowers that are warty outside and white inside. The sepals and petals are joined, forming a tube 10–12 mm (0.4–0.5 in) long. The petals have a few blunt teeth on the edges. The labellum is 9–10 mm (0.4–0.4 in) long, 4–5 mm (0.16–0.20 in) wide and white with irregular edges. Flowering occurs from November to January.[2][3][4][5] Taxonomy and namingGastrodia lacista was first formally described in 1991 by David Jones from a specimen collected near Albany in 1989. The description was published in Australian Orchid Research.[6] The specific epithet (lacista) is a Latin word meaning "torn"[7] referring to the edges of the labellum.[3] Distribution and habitatThe western potato orchid grows in woodland and forest in leaf litter between Bunbury and Albany.[2][3][4][5][8] References
