ARBORETUM ET FRUTICETUM BRITANNICUM. 



glaucous beneath, and in the fruit being much more divergent. Burk of the 

 trt'.niv white. Leaves 3 in. to > 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.

'it A. P. 2 opidifolia. A. opulifolium Hort. ; A. 



trilobatum Hort. ; A. barbatum Hort. (Our 

 fig. 132.) Leaves and fruit smaller than 



in the species, as shown in fig. 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. Pseudo-PIatanus, but 



to be much smaller. It is a native of the 



Alps and Pyrenees. Introduced in 1812. 



Height 15 ft. to 20 ft. 

 t A. P. 3 longifolia. A. longifoliuni Booth. Leaves 



more deeply cut, and the petioles much 



longer than in the species. Altogether a tree of very remarkable 



aspect. 

 A. P. 4 Jldvo variegdta. A. P. lutescens 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. 

 t K. P. 5 dlbo variegdta Hayne. Of all the variegated varieties of A\er, 



it must be acknowledged that this is the most ornamental ; especially 



in sjjring, when the leaves first expand. 

 I' A. P. (j 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, tht 



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 

 Hodgkhiis Seedling, with yellow-blotched leaves ; and another, called Leslie's 



131. A. P. opulifMium.
