The second pic in Mkb's first post is Passiflora quadrangularis which does describe the square stems on it.
Just to remind you, this is the Brug forum, here . . . Passi pictures are most welcome on the Tropicals forum or Florida Gardening, too.
Hey, Mkb, could you sell me a cutting of Angel's Goldface in the fall, September maybe? I think it's too hot to be mailing cuttings over summer.
