About our data


The primary data source is The International Orchid Register, as published by the Royal Horticultural Society. For species, this source is augmented by data from the World Checklist of Vascular Plants (WCVP).


When possible, direct hyperlinks are provided from pages on this site to pages owned by the data publishers. In addition, a footer is rendered on every page acknowledging attribution and copyright.


Every effort has been made to present data as true to source as possible. Before raising a data quality issue, please kindly verify that the representation of data on this site actually differs from that of the source.
