Tree. Maij. 



A large, handsome tree, of quick growth, with a smooth ash- co- 

 loured bark, and round, spreading branches. Leaves on long 

 footstalks, 4 or 5 inches broad, palmate, with 5 acute, variously 

 serrated lobes ; the middle one largest j 2 outermost very small; 

 veiny, smooth, except a little hairy tuft at the base ; pale or 

 glaucous beneath. Clusters axillary, solitary, pendulous, com- 

 pound, many-flowered, downy. Fl. green, the size of a currant- 

 blossom, Anthers hairy between the lobes. Capsules with 2, 

 or 3, broad spreading wings, above an inch long. 



The wood is white and soft, useful for many purposes. The sap is 

 said to yield some portion of sugar, and to be made into wine 

 in the Highlands of Scotland. 



Our variety /3, pointed out by the late Mr. Andrew Caldwell of 

 Dublin, appears to have more elongated, distantly serrated.
