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.
