Acer miyabei - UWBG Washington Park Arboretum, Seattle, accession 1949.
*These photos should be treated as Questionable*
It's likely it's just a Hedge maple.
Assuming species assignment is correct (looks like the leaves of a hedge maple) might that last one be an example of 'Morton'?
That one looks more like a Field Maple.
I'll find out where the seed heritage is from - that's most-likely the case here.
In other words we both think it's Acer campestre (English maple, common maple, field maple, hedge maple, small leaved maple, English cork maple). As can be seen in preceding photos A. myabei produces a leaf more like that of A. platanoides.
Ron, you were right on track.
"The Acer miyabei was a volunteer seedling from one of the trees at Morton Arb, from which that cultivar was named. I selected it from the group because it just happens to be a very dense one with great color."
Likely a case where it looked different because it was a different species. Van Gelderens, Maples for Gardens (1999, Timber Press, Portland) describe the leaves of A. miyabe this way:
"Leaves to 15 cm (6 inches) wide, shape same as A. campestre but larger, five-lobed, olive-green; fall color yellow"
Ron B - Acer campestre is Field Maple. The rest of that cr*p you listed can be (and should be) deleted.
Specimens of Acer miyabe that I've seen have fairly similar leaf shape to Field Maple, but larger, and more deeply lobed. But very vigorous specimens of Field Maple can be strikingly similar and tricky to distinguish.
