For starters, you could browse this website
http://www.orchidspecies.com/
It is an encyclopedia of species orchids & probably the oldest on the net.

I see you are in England so you could also check the RHS
http://www.rhs.org.uk/Plants

I read an article in a very old National geographic magazine long ago
about orchids and I was amazed about how many there were with new
variety's being discovered every year. This makes curious about how many
are catalogued now. Any help available would be appreciated.
