Description
Gastrodia lacista is native to South Australia, loose leaf green plants art from the family of the orchid (Orchidaceae). It was first described in 1991 by David Lloyd Jones. Gastrodia lacista is a leafless plant that has given up photosynthesis and therefore no longer forms chlorophyll . Instead, it lives myko-heterotrophically from a fungus . The fleshy, bulbous rhizome gave the plant its English trivial name "Potato Orchid" ("potato orchid"). The leafless flower stalk is 25 to 50 inches high. It has five to thirty tubular, nodding flowers , with flowering from November to early January. The bell-shaped flowers are 10 to 20 millimeters long, about 6 millimeters wide, pale brown outside and inside white with a yellow gullet. The petals are slightly thickened at the irregular edges, the labellum is white.
