A few years ago there was a conversation on this site about a large shaggy bark maple in central Maine that no one seemed to be able to identify. I'm in southern Maine and have come across several large, old (at least 100 years old) 3-lobed maples that I can't identify. The leaves look a bit like mountain maple but since that's a shrubby plant, that doesn't work. Here are a couple of pictures. Any suggestions are greatly appreciated!
I stand corrected! I'm new to maples and most folks around here (at least that I talk to) call the red variety of Norway maple "red maple". Ah, the reason for sciientific nomenclature. Also, the "best" key I use has red maple leaves represented with a distinctly 5-lobed outline. Upon further looking, however, I see that that isn't always the case.
