the spring. Fruit often reddish, small, with the wings at

5. =Acer Pseudoplatanus=, L. (SYCAMORE-MAPLE.) Leaves thickish, cordate,
downy beneath, with 5 rather crenately toothed lobes, on long, often
reddish petioles. Flowers in long pendulous racemes, appearing after the
leaves. Fruit hanging on the tree till after the leaves fall in the
autumn, the wings forming about a right angle. A rather large, spreading
tree, 30 to 80 ft. high, with reddish-brown twigs. Cultivated; from

6. =Acer saccharinum=, Wang. (SUGAR OR ROCK MAPLE.) Leaves deeply 3- to
5-lobed, with rounded notches; lobes acute, few-toothed; base
heart-shaped, smooth above, glaucous beneath. Flowers hanging in
umbel-like clusters at the time the leaves are expanding in the spring.
Fruit with wings not quite forming a right angle. A large (50 to 100 ft.
high), very symmetrical tree, ovate in form, with whitish-brown twigs.
Wild throughout, and extensively cultivated in the streets of cities.

Var. _nigrum_, Torr. and Gray. (Black Sugar-maple.) Leaves scarcely
paler beneath, but often minutely downy; lobes wider, often shorter and
entire; notch at the base often closed (the under leaf in the figure).
