Description

Gastrodia queenslandica is a leafless terrestrial, mycotrophic herb that has a thin, fleshy, brittle, light brown flowering stem bearing one or two yellowish brown, tube-shaped flowers that are orange-coloured inside. The sepals and petals are joined, forming a tube about 10 mm (0.4 in) long with spreading tips. The tube is rough on the outside and orange-coloured and smooth inside. The labellum is about 5.5 mm (0.2 in) long, 3 mm (0.1 in) wide and completely enclosed in the tube. Flowering occurs from November to January.[2][3]

Taxonomy and naming

Gastrodia queenslandica was first formally described in 1964 by Alick William Dockrill who published the description in The North Queensland Naturalist.[1][4] In 2004, David Jones and Mark Clements changed the name to Demorchis queenslandica but the change has not been accepted by the World Checklist of Selected Plant Families.[5]

Distribution and habitat

Rainforest bells grows in near coastal rainforest between the Russell River and the McIlwraith Range but is rarely seen.[2][3]

Conservation

This orchid is classed as "near threatened" under the Queensland Government Nature Conservation Act 1992.[6]
