The first one seems to be a shrub or a tree and it's from the forest. I've found the second one on a meadow and, judging by the inflorescence, it seems to be some Apiaceae. After searching through most of the family, I still couldn't find it. Thanks.
Thank you very much, Ron B. I can't believe no one here recognizes the other(s), you were my only hope. And by any chance, does anyone know where I can find a Hieracium expert on the internet?
