glaucous beneath, and in the fruit being much more divergent. Bark of the 
trunk white. Leaves 3 in. to 5 in. in length, generally wider than long. The 
buds have a fine ruddy tint, especially in spring before they expand. The tree 
in England is rather tender, and never attains a large size; but in America the 
timber is valuable, and the sap produces sugar. American seeds.

Varieties. 
% A. P.2 opulifolia. A. opulifolium Hort. ; A. 
trilobatum Hort. ; A. barbatum Hort. (Our 
fig. 132.) — Leaves and fruit smaller than 
in the species, as shown in jig. 155. of the 
leaves, in the plate forming p. 114. We have 
no doubt of this being the A. opulifolium 
of Thuillier and Villars, L’E’rable duret, and 
L’E‘rable ayart, Fr., which is said by these 
authors to resemble A. Pseido-Platanus, but 
to be much smaller. It is a native of the 
Alps and Pyrenees. Introduced m 1812. 
Height 15 ft. to 20 ft. 
* A. P.3longifdlia. A.longifoliam Booth.—Leaves 
more deeply cut, and the petioles much Tal; Askvopulissinita: 
longer than in the species. Altogether a tree of very remarkable 
aspect. ‘ 
4 A. P. 4 fldvo variegdta. — A. P. lutéscens Hort.; the Corstorphine 
Plane. — Leaves variegated with yellow. The original tree stands 
near an old pigeon-house in the grounds of Sir Thomas Dick 
Lauder, Bart., in the parish of Corstorphine, near Edinburgh. Seeds 
of this variety, sown, have produced plants with the character of the 
parent to a certain extent. 
* A. P. 5 dlbo variegdta Hayne.—Of all the variegated varieties of A‘cer, 
it must be acknowledged that this is the most ornamental ; especially 
in spring, when the leaves first expand. ; 
+ A. P. 6 purpurea Hort. — Leaves of a fine purple underneath. This 
variety was found in a bed of seedlings, in Saunders’s Nursery, 
Jersey, about 1828, and is now to be met with in all the principal 
nurseries. The tree has a very singular effect when the leaves are 
slightly ruffled by the wind, alternately appearing clothed in purple 
and in pale green. In spring, when the leaves first expand, the 
purple bloom is less obvious than when they become matured, at 
which time it is very distinct. 
Other Varieties. In the garden of the Hort. Soc. there is a variety called 
Hodgkins’s Seedling, with yellow-blotched leaves ; and another, called Leslie’s
