Zeuxine exilis, commonly known as Ridley’s Ground Orchid or Ridley’s Jewel Orchid, is a terrestrial orchid belonging to the subfamily Orchidoideae. It is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean.

History[edit]

The orchid was first recorded and collected in October 1904 by the first director of the Singapore Botanic Gardens, Dr Henry Ridley. It was then not officially recorded for over a century; in the third Christmas Island National Park Management Plan (2002) it was considered possibly extinct.[2] Then in 2009 it was found and collected again by visiting research scientist Dr Peter Green.[3][4]
