OOh... those flowers take my breath away!! I love the symmetry of the lip and the petals... they are almost perfectly equally proportioned! It would seem that this is a peloric plant, yes? I've never heard of a Guaricattonia before, so I'm not "up" on all their characteristics, but I'm just amazed at the symmetry between the lip and the petals! And the slight flares of yellow going up into the petals would seem to say 'peloric' to me.
Anyway, this one is going right on my wish list!! GORGEOUS!!!
