Nervilia is a genus of orchid with about 65 species widely distributed across most of sub-Saharan Africa (South Africa, southern Asia (Saudi Arabia, India, China, Japan, Indochina, Indonesia, etc.), Australia, and various islands of the Pacific and Indian Oceans.[1] Six species occur in Australia (2 or 3 of these endemic),[2] with 16 in India,[3] 10 in China[4] and 5 in South Africa.[5]

There are flowering and non-flowering varieties - the non-flowering plants have only a single leaf and are either ground-hugging or erect. The flowering varieties have a fleshy flower stem with only one or a few flowers and a leaf which arises later at the base of the dying flower stem. The flowers of the Australian species are rarely seen in the wild because they appear soon after the first heavy rains of the wet season and only live for 1 to 4 days.[2]

Nervilia is the sole member of its subtribe, the Nervilliinae.
