If you want to start a friendly competition with kMarch the link he uses to the RHS database is
http://www.rhs.org.uk/research/regis..._parentage.asp
It is not an easy database to use. The slightest mis-spelling with get you a message that it is not registered. So I trust the data when I find a match and blame my typing when I do not. Also the database does not use abbreviations you must spell out the full name no B use Bassovola etc.
I agree scientifically that the family Laelia was totally misnamed but I regret seeing the change. A lot of hobbyist will buy plants thinking they have something new only to find they already own it. So be careful.
