Glossodia is a genus of mostly purple orchids from Australia. In spring vast numbers of Glossodia major flower on uncleared land.

There are only two recognised species:^[2]

• Glossodia major R.Br. - waxlip orchid, native to Queensland, New South Wales, Victoria, Tasmania and South Australia.
• Glossodia minor R.Br. - small waxlip orchid, native to Queensland, New South Wales and Victoria.

Cultivation

Glossodia are difficult to maintain in cultivation. Growing from seed in vitro has yielded very poor results, and plants taken from the wild usually last only a few years. This may be due to the plants' complete reliance on a symbiotic fungus for nutrition. These orchids form no roots and obtain nutrients from mycorrhizal fungi. A reasonably successful solution to this has been to grow new plants in the same pot each year. This usually requires hand pollination, but it can result in a better yield.
