Description
[edit]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]
