....and so begins the struggle: Is THIS it??
* I would have to see the oil/sap
* I would have to cross cut it to see the hollow interior structure
* At closer look, was there maroon highlighting on the green?
As I mentioned above, there are at least 3 other common look alikes (this one looks like the wild parsley due to the leaf structure, but without a specimen, I don't dare guess)
THIS IS A PLANT THAT YOU DO NOT WANT TO MAKE A CASUAL MISTAKE WITH, so avoid anything with a white umbel (whoorl-like flower structure) and parsely-like leaves in the wild.
Toxicity? Just getting the sap on your hands and accidentally transferring a miniscule amount can be deadly. There is strict protocol when handling this deadly beast.
