Lately I am taxonomic advisor to the Greek Orchid Society where I manage the taxonomic and cultural databases (involving one with the cultivated plants, and one with natives).
I am what you would consider a lumber, however the reality is that since I have seen million of Ophrys in their natural environment, as well as growing a few from seed and seeing other plants grown from seed, I make a clear distinction between Delforgian micro-species (and the movement of species-mongering he begun, which advocates that Europe has the orchid diversity flora of Equador), and real species.
