Yeah absolutely. A few plant IDs I've tried have said very confidently that a plant is a specific thing, but then after reading descriptions and checking the scientific name it's very clearly not that. It does generally give a good place to start though. So maybe it's not black cohosh but it leads me to find out it's bugbane, for instance.

I have eaten some things I've foraged, but only things I've checked and double checked don't have any dangerous lookalikes. Thankfully it's hard to go wrong with a blackberry vine.
