leaves, which though, roughly speaking, are si- 
ilar to those of the Sycamore—being, like them, 
five-lobed—are, nevertheless, very characteristic 
and distinct. The Maple, in the first place, has

leaf has also a more decidedly red hue, with a

through the leaf than is the case in the leaf of 
Acer pseudo-platanus. Its surface, too, is more 
glossy, both on its upper and under side, than the 
Sycamore leaf. In the deep indentations dividing 
the lobes of its leaves, Acer campestre some- 
what resembles the Oriental Plane; but there is 
a conspicuous rotundity in the apices of the lobe 
divisions. The venation very closely resembles 
that of the Sycamore leaf, a principal vein run-

each side to the leaf margin. It will be noticed 
that the Maple leaf is often studded with small red 
excrescences. These are tenanted by insects, by

green flowers of this Tree are borne on racemes, the
