Plantfinder at http://www.rhs.org.uk/rhsplantfinder/ This is a
directory of names of plants offered for sale in the UK. Standards are
pretty high, both as concerns correct spelling and currency of names.

A competing, but as yet small-scale plantfinder
http://www.mobot.org/gardeninghelp/p...der/Search.asp

There's a Dutch equivalent at

http://www.plantago.nl/plantindex/

tho' it seems to have more nomenclatural errors than the RHS
Plantfinder.
