I looked at all the Blue Grottos on OWiz and I just looked at that post from OT 2006 that you linked, Roy, and I have to say, again, that I don't think it's Blue Grotto, although it's close. For one thing, this catt is NOT blue in any way - it's magenta and fuschia - as I said, the colors I've posted are pretty accurate. I really do think it's a Portia (Porcia?) clone - 'Mayflower' is nearly identical. I don't know what to think about the unifoliate/bifoliate aspect. The double sheath, as well as the blooming time (September) indicate labiata, while the number of blooms indicate bowringiana (9 on one and 8 on the other). The pbulbs look like labiata. All of which, I know, only really suggests both labiata and bowringiana in the background.
