66o The Trees of Great Britain and Ireland 



glabrous, remaining green throughout the first and second years. Leaves (Plate 205, 

 Fig. 8) about 5 inches long by 5^ inches wide; lobes five or three, with their apices 

 pointing away from the base of the leaf and ending in long sharp points ; margin 

 repand, non-ciliate ; upper surface dark green, shining, glabrous ; lower surface light 

 green, dull, glabrous except for pubescent tufts in the axils of the nerves ; petiole 

 with milky sap. 



Flowers smaller than those of A. platanoides, in corymbs. Fruit, glabrous, 

 with horizontally spreading wings, each key about an inch long. 



A variety with deeply-cut leaves is described by Tenore ; but it is not 

 apparently in cultivation. 



This species is readily distinguished by the pyramidal habit, striped bark, and 

 glaucous shoots. It grows in woods in the mountains around the Bay of Naples, 

 and according to Spach ' is also found in the mountains of Calabria. (A. H.) 



Acer Lobelii, which Loudon treats as a variety of the Norway maple, is so 

 distinct in its habit of growth and in its bark that it is well worth cultivation. The 

 largest we have seen in England is at Grayswood, a handsome tree with erect 

 branches about 40 feet high. It is quite hardy as far north as Yorkshire, where 

 Sir Charles Strickland has planted a good many which are now from 25 to 40 feet 

 high and growing vigorously. They all have an erect, fastigiate habit. There are 

 two good specimens in Kew Gardens. A large tree was reported "^ to be growing 

 in 1839 at Croome Court, near Worcester; but when this place was visited by 

 us in 1905, it could not be found. 



At Verrieres, near Paris, in M. P. de Vilmorin's grounds, this tree has attained 

 55 feet in height by 5 feet in girth. (H. J. E.)

A tree attaining 60 feet in height ; bark smooth, usually striped with white 

 lines or bands. Young branchlets green, glabrous, not glaucous except in one 

 variety, remaining green and smooth in the second year in some varieties, becoming 

 grey or brown with irregular fissures in others. Leaves (Plate 205, Fig. 9), 

 averaging 4 inches long and 4^ inches broad, cordate at the base, entire in margin ; 

 lobes long, cuspidate or caudate-acuminate, bristle-pointed, five or seven in number
