|Ridley’s Ground Orchid|
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.
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. Then in 2009 it was found and collected again by visiting research scientist Dr Peter Green.
