each one coarsely and irregularly toothed ; they are smooth except for small 

 tufts of down in the axils of the veins. Flowers minute, each on a stalk to J 

 in. long, produced in May with the leaves, on very slender racemes 2 to 4 ins. 

 long, and downy. Fruit in long racemes ; keys I in. long, smooth ; the wings 

 obliquely ovate, -j|- in. wide, diverging from each other at an angle of 60 or less. 

 Native of Japan. This interesting maple belongs to the same group as A. 

 nikoense, but is easily distinguished by the smooth, slender leaf-stalks, the stalked 

 basal leaflets, and the bright green under-surface and coarse toothing of the
