EVIDENCE FOR A THIRD SPECIES OF GASTRODIA (POTATO-ORCHID) IN TASMANIA

摘要

The genus Gastrodia is represented by about 35 species, 7 endemic in Australia, the others distributed through India, Indonesia, Malaysia, New Guinea and New Zealand (Jones 2006). The plants have a rootless fleshy rhizome that sometimes looks like a potato (hence the vernacular name) and a leafless fleshy to wiry brown flower stem (Jones 2006).
