D. gracilicaule is a native of Moreton Bay in Queensland, 
of the Macleay and Clarence rivers in New South Wales, 
and of Lord Howe’s Island. It is an inconspicuous species, 
and probably often overlooked. The specimen here figured

of Kew, near Melbourne, Australia, and the drawing was 
made in March of last year.
