|After looking at many sites and pictures, I'm not much better off, practically speaking. . .now that I see there may be kore than 3 leaves, it seems like ANYTHING could be PI!! Surely there is some sort of chemical test, i.e. put a drop of some concoction on a leaf, and if it changes colour, it is (or isn't) PI.
I'm in a southern Ontario forest, and have lots of different 3 leaf plants, including some with long stemmed small pink flowers which grow taller than the leaves...does that sound like any kind of PI...I've only seen pink or green flower
