À. Læ̀tum.
9. Àcer Læ̀tum. (Colchicum-leaved Maple.) Leaves 5- to 7-lobed, scarcely heart-shaped at base, smooth and green on both sides; juice milky; the lobes usually without any notches or irregularities, sometimes with about three winding sinuations. Flowers in erect corymbs. Differs from Acer platanoides in having the lobes of the leaves more nearly entire, and the fruit much smaller with wings not so broadly spreading.
À. campéstre.
10. Àcer campéstre, L. (English or Cork-bark Maple.) Leaves cordate, with usually 5 roundish lobes, sparingly crenate or rather undulated; juice milky. Racemes of flowers erect, appearing after the leaves in spring. Wings of the fruit broadly spreading; fruit ripening very late. A low (15 to 30 ft. high), round-headed tree, with the twigs and smaller branches covered with corky bark. Occasionally cultivated; from Europe.
Var. variegatum has white blotched leaves.
À. palmàtum.
11. Àcer palmàtum, Thunb. (Palmate-leaved Japan Maple.) Leaves small, smooth, palmately parted into 5 to 9 quite regularly serrated lobes. Flowers in small umbels. A very low tree, almost a shrub; cultivated; from Japan; probably hardy throughout. There are a great number of Japan Maples, many of them probably varieties of this species, others hybrids. The leaves of some are so divided and dissected as to form merely a fringe or feather. In color they range from pure green to the richest reds.
