ACER NEGUNDO, L. 151 



Fruit. In long, drooping racemes of pale green keys, set 

 at a wide but not uniform angle ; distinguished from the 

 other maples, except A. spicatum, by a small cavity in the 

 side of each key ; abundant ; ripening in August. 



Horticultural Value. Hardy, under favorable conditions, 

 throughout New England. Prefers a rich, moist soil near 

 water, in shade ; but grows well in almost any soil when once 

 established, many young plants failing to start into vigorous 

 growth. Occasionally grown by nurserymen, but more readily 

 obtainable from northern collectors of native plants.
