I can lump phillipinense and laevigatum together... No problems for me...
Main reason is that as far as I know (and I'm probably wrong) the major difference between the varieties is the petal stance and degree of twist. From that, I'd wager that the plant pictured at the top of this thread is really phil x laevigatum. Or, it has a substantial percentage of laevigatum in the background... Which makes it???
This is the reason I'm a lumper. Largely because there is no way to sort out plants now. If they are jungle collected, that is one thing. But, after they have been in captivity for years, and people breed different varieties together without keeping track, it gets hard. I don't mind leaving it phil. var. laevigatum, phil var. roebelinii, etc, but still I don't trust that they are genetically 'pure'.
