Abstract

Rhizanthella speciosa, a new species of the remarkable Australian underground orchids, is  described as new from New South Wales. The new species, which is morphologically distinct and apparently  also genetically distinct from its congeners and strikingly beautiful with its sea-anemone-like flowerheads and  prominent attenuate sepals, grows in a different habitat than its geographically closest relative.
