Okay, I found these 3 sites for Florida in particular which show some good photos & give good info. Honestly, I keep see-sawing between oak & ivy.

I have a friend who is taking photos of their poison ivy in Alabama. The husband there says my stuff is poison oak IHO.
Now that I've had some education on the subject; I will study & take more photos next time we go to the property. I'm not as afraid now as I walked all through the stuff the last 3 times we were out there & logically from all I read, I would have the oil on my tennis shoes which I have been wearing since then & I'm okay. Furthermore, I am not sensitive to Mango nor to Schinus terebinthifolius aka Brazilian Pepper. I never knew until today that Brazilian pepper is in the same group & contains urushiol.
There was no sign of blooms when we were there Saturday. I will keep looking as that will give us the best clue.
I will not add this to the db until/unless I can be sure we know which it is.
