Abstract

Gastrodia Brown (1810: 330; Gastrodieae, Epidendroideae) comprises mycoheterotrophic orchids from throughout the temperate and tropical regions of Asia, Oceania, Madagascar and Africa (Chung & Hsu 2006, Cribb et al. 2010, Tan et al. 2012). The genus is characterized by fleshy tubers, as well as the absence of normal leaves, union of sepals and petals and two mealy pollinia that lack caudicles. Furthermore, many Gastrodia species within section Codonanthus (Schlechter 1911, Tuyama 1967) produce inflorescences that are only 3–15 cm in length at flowering (Chung & Hsu 2006) and, owing to their short flowering seasons and dwarf habits, are seldom noticed when flowering (Tuyama 1982, Suetsugu et al. 2012). The identification of Gastrodia species requires detailed observation of floral features, such as lip and column morphology, that are hidden within the perianth tube.
