i was looking up some info on a couple of orchids i bought at the auction and found this website. LOTS AND LOTS of species, subspecies and varieties. its just a description of the plant, basic growing info and pictures but it has a huge list of individual orchids. great if you've found some odd ball orchid and want to see what a flower will look like and a basic idea of how to grow it. definatly one to bookmark. anyways here is the site:
