the spring. Fruit often reddish, small, with the wings at
about a right angle. A rather small, somewhat spreading tree with
reddish branches; wild in wet places and often cultivated.

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
Europe. Many varieties of this species are sold by the nurserymen; among
them may be mentioned the Purple-leaved, Golden-leaved, Silver-leaved,
Tricolored, etc.

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).
Found with the other Sugar-maple, and quite variable.

7. =Acer macrophyllum=, Ph. (LARGE-LEAVED OR CALIFORNIA MAPLE.) Leaves
very large, 8 to 10 in. broad; 5-, sometimes 7-lobed, with deep, rounded
notches; lobes themselves somewhat 3-lobed and repand-notched; pubescent
beneath. Flowers yellow, in erect panicles, fragrant, blooming after the
leaves are expanded. Fruit large, with the seeded portion hairy; wings
at about a right angle. Tree very large (100 ft. high); wood soft,
whitish, beautifully veined. Twigs brown; buds green. Cultivated; from
the Pacific coast, but not hardy north of 40 deg. N. latitude.

8. =Acer platanoides=, L. (NORWAY MAPLE.) Leaves large, smooth, 5-,
rarely 7-cleft, with cordate base; lobes acute, with few coarse, sharp
