Banana Spider

Thanks for the suggestions. I'll try to find out what it is.

Except for the vertical web, this spider looks like a Leucauge species. There are only two Nephila species in Florida, and I just don't think it looks like either one. I can maybe see juvenile Nephila clavipes- but it's a tough call, especially with this image.

The clumps of hair on the legs suggest Nephila

It's kind of hard to tell from this image, but I would guess Leucauge venusta. See: http://bugguide.net/node/view/863215
