them have tapering bases. All intermediate gradations occur, how- 
ever. The fruit in New England and New York is rarely abundant, 
according to the writer’s experience, but in the North the bushes are

A. laevis differs from A. canadensis in the size and coloring of the 
leaves at flowering time, texture and shape of the leaves at maturity, 
number of teeth, shape of the teeth, length of the pedicels, size of the 
hypanthium, and length and shape of the sepals. When growing 
together, the contrast in appearance at flowering time is striking. The 
loose racemes and bronzy foliage of A. laevis give a rich somewhat 
drooping effect; while in A. canadensis the whole tree is pure white 
and usually stiffer. 
The following typical specimens have been examined. New-
