Dear Bob...my understanding is that Mayo synonymised P.mello-barretoanum
under P. bipinnatifidum in his revision of the subgenus Meconostigma.
As I'm at work I don't have a copy here to check but that's what my
memory tells me. I have only seen photos of this plant but they do seem
pretty different plants to my amateur eye. I would dearly love to obtain
a plant or some seeds...any one out there who could help?
I'll check with my copy of Mayo and report back tomorrow!
