Mountain Maple

=Habitat and Range.=--In damp forests, rocky highland woods, along the

sides of mountain brooks at altitudes of 500-1000 feet.

From Nova Scotia and Newfoundland to Saskatchewan.

Maine,--common, especially northward in the forests; New Hampshire and

Vermont,--common; Massachusetts,--rather common in western and central

sections, occasional eastward; Rhode Island,--occasional northward;

nnecticut,--occasional in northern and central sections; reported as

far south as North Branford (New Haven county).

Along mountain ranges to Georgia.

=Habit.=--Mostly a shrub, but occasionally attaining a height of 25

feet, with a diameter, near the ground, of 6-8 inches; characterized by

a short, straight trunk and slender branches; bright green foliage

turning a rich red in autumn, and long-stemmed, erect racemes of

delicate flowers, drooping at length beneath the weight of the maturing


=Bark.=--Bark of trunk thin, smoothish, grayish-brown; primary branches

gray; branchlets reddish-brown streaked with green, retaining in the

second year traces of pubescence; season's shoots yellowish-green,

reddish on the upper side when exposed to the sun, minutely pubescent.

=Winter Buds and Leaves.=--Buds small, flattish, acute, slightly

divergent from the stem. Leaves simple, opposite, 4-5 inches long,

two-thirds as wide, pubescent on both sides when unfolding, at length

glabrous on the upper surface, 3-lobed above the center, often with two

small additional lobes at the base, coarsely or finely serrate, lobes

acuminate; base more or less heart-shaped; veining 3-5-nerved,

prominent, especially on the lower side, furrowed above; leafstalks

long, enlarged at the base.

=Inflorescence.=--June. Appearing after the expansion of the leaves, in

long-stemmed, terminal, more or less panicled, erect or slightly

drooping racemes; flowers small and numerous, both kinds in the same

raceme, the fertile near the base; all upon very slender pedicels; lobes

of calyx 5, greenish, downy, about half as long as the alternating

linear petals; stamens usually 8, in the sterile flower nearly as long

as the petals, in the fertile much shorter; pistil rudimentary, hairy in

the sterile flower; in the fertile the ovary is surmounted by an erect

style with short-lobed stigma.

=Fruit.=--In long racemes, drooping or pendent; the keys, which are

smaller than those of any other American maple, set on hair-like

pedicels, and at a wide but not constant angle; at length reddish, with

a small cavity upon one side.

=Horticultural Value.=--Hardy in cultivation throughout New England;

prefers moist, well-drained, gravelly loam in partial shade, but grows

well in any good soil; easily transplanted, but recovers its vigor

rather slowly; foliage free from disease.

Seldom grown in nurseries, but readily obtainable from northern

collectors of native plants.
