Orchid Genera List

Based on the International Register and Checklist of Orchid Hybrids

The original list was prepared for the European Orchid Council Conference and Exhibition in London 2003 by Dr Cedric Maunder.

Tom Houghton maintained the list until May 2013.

Zoe Parfitt updated it to the end of 2014.

Chris Barker has now taken over keeping the list up to date.

It is a long list; please email Chris if you spot any errors. [email protected]
