ish, of 2 lobes. Ger7n. superior, compressed, of 2 lobes. 

 Si7/le cylindrical, gradually elongated. Stigm. 2, or 3, 

 pointed, revolute. Caps, as many as the stigmas, com- 

 bined at the base, roundish, compressed, each termina- 

 ting in a rounded, firm, membranous, spreading wing. 

 Seeds 1 or 2, roundish ; cotyledons folded. 



The anthers are imperfect in some of the flowers, the pistils 

 in some others, but many flowers are perfect in both or- 

 gans. The divisions of the calyx, as well as the petals, 

 vary in number, and the stamens accord with them. 



Trees or shrubs, with opposite branches and leaves; the lat- 

 ter lobed, cut mostly palmate, stalked, smooth, decidu- 

 ous, without stipidas. Fl. green or yellowish, numerous, 

 in drooping or upright, often downy, clusters. Wood va- 

 luable, often beautiful.

In hedges, and about houses, common, but not truly wild. 



Tree. May. 



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 ; 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.
