That's an interesting looking passionvine. Never seen that one before, but I've heard of it. It is classified as an exotic invasive in Florida. You sure have been finding a lot of the "nasty" Florida plants!
Luckily most are not in my backyard like this one is. It is slated for removal but I thought I'd trade it and it's offspring to someone that can grow it without it becoming a menace. One finds lots of exotics along roadsides and fields like the ones I explore.
