Very distinct from any of the preceding species, in the spreading umbel- 
liferous appearance of the branches, and the flat, heart-shaped, very rough- 
surfaced leaves, which are almost always entire, but which, nevertheless, are 
occasionally found as much lobed and cut as those of any other of the genus. 
As a tree ornamental from its very singular form, it deserves a place in every 
pleasure-ground ; and it is particularly adapted for giving interest to the 
scenery of a suburban garden.
