Description

Gastrodia crebriflora is a leafless terrestrial, mycotrophic herb that has a shiny, fleshy, pale brown flowering stem bearing ten and thirty five flowers pale brown to white, drooping, tube-shaped flowers. The sepals and petals are joined, forming a tube about 12–14 mm (0.5–0.6 in) long with spreading tips. The tube has a warty base and is white inside. The labellum is about 10–12 mm (0.4–0.5 in) long, about 3.5 mm (0.1 in) wide and completely enclosed in the tube. Flowering occurs from September to October but the flowers are self-pollinating and short-lived.[2][3]

Taxonomy and naming

Gastrodia crebriflora was first formally described in 1991 by David Jones from a specimen collected on the Blackdown Tableland in 1988. The description was published in Australian Orchid Research.[4] The specific epithet (crebriflora) is derived from the Latin words creber meaning "thick", "close" or "numerous"[5]:790 and flos meaning "flower",[5]:338 referring to the many crowded flowers on this orchid.[3]

Distribution and habitat

The dense potato orchid grows in loose groups in tall forest on the Blackdown Tableland.[2][3]

Conservation

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