I've got three specimens. Two are exactly the same, labeled as albo x veitchii, and a third, very much like the others, I got labeled as N. x merrillalata. I think the ones I have are an older grex that has been floating around Florida for quite some time. I'm not sure of their origin. I've never had any that look like yours and I have always been a little disappointed that mine don't show that much veitchii.
