Well said, James. A lot of new iNatters submit pictures of “trees”. Even “mangrove” is polyphyletic.
Even if we could taxonomically reclassify a tree, its role in our lives would not change.
A tree is still a tree to the bird nesting in its branches, to the artist inspired by its beauty, and to the lovers lying in its shade.
Some things are defined, not by their classification, but by their meaning in our lives.
