White Ash
=Habitat and Range.=--Rich or moist woods, fields and pastures, near
streams.
Newfoundland and Nova Scotia to Ontario.
Maine,--very common, often forming large forest areas; in the other New
England states, widely distributed, but seldom occurring in large
masses.
South to Florida; west to Minnesota, Nebraska, Kansas, and Texas.
=Habit.=--A
all forest tree, 50-75 feet high, with a trunk diameter of
2-3 feet; rising in the rich bottom lands of the Ohio river 100 feet or
more, often in the forest half its height without a limb. In open
ground the trunk, separating at a height of a few feet, throws off two
or three large limbs, and is soon lost amid the slender, often gently
curving branches, forming a rather open, rounded head widest at or near
the base, with light and graceful foliage, and a stout, rather sparse,
glabrous, and sometimes flattish spray.
=Bark.=--Bark of trunk in mature trees easily distinguishable at some
distance by the characteristic gray color and uniform striation; ridges
prominent, narrow, flattish, firm, without surface scales but with fine
transverse seams; furrows fine and strong, sinuous, parallel or
connecting at intervals; large limbs more or less furrowed; smaller
branches smooth and grayish-green; season's shoots polished olive green;
leaf-scars prominent.
=Winter Buds and Leaves.=--Buds short, rather prominent, smooth, dark or
pale rusty brown. Leaves pinnately compound, opposite, 6-12 inches long;
petiole smooth and grooved; leaflets 5-9, 2-5 inches long, deep green
and smooth above, paler and smooth, or slightly pubescent (at least when
young) beneath; ovate to lance-oblong, entire or somewhat toothed; apex
pointed; base obtuse, rounded or sometimes acute; leaflet stalks short,
smooth; stipules and stipels none.
=Inflorescence.=--May. In loose panicles from lateral or terminal buds
of the previous season's shoots, sterile and fertile flowers for the
most part on separate trees, numerous, inconspicuous; calyx in sterile
flowers 4-toothed, petals none, stamens 2-4, anthers oblong; calyx in
fertile flowers unequally 4-toothed or nearly entire, persistent; petals
none, stamens none, pistil 1, style 1, stigma 2-cleft.
=Fruit.=--Ripening in early fall, and hanging in clusters into the
winter; a samara or key 1-2 inches long, body nearly terete, marginless
below, dilating from near the tip into a wing two or three times as long
as the body.
=Horticultural Value.=--Hardy throughout New England; prefers a rich,
moist, loamy soil, but grows in any well-drained situation; easily
transplanted, usually obtainable in nurseries, and can be collected
successfully. It is one of the most desirable native trees for landscape
and street plantations, on account of its rapid and clean growth,
freedom from disease, moderate shade, and richly colored autumn foliage.
As the leaves appear late in spring and fall early in autumn, it is
desirable to plant with other trees of different habit. Propagated from
seed.

RED ASH. BROWN ASH. RIVER ASH.
=Habitat and Range.=--River banks, swampy lowlands, margins of streams
and ponds.
New Brunswick to Manitoba.
Maine,--infrequent; New Hampshire,--occasional, extending as far north
as Boscawen in the Merrimac valley; Vermont,--common along Lake
Champlain and its tributaries (Flora of Vermont, 1900); occasional in
other sections; Massachusetts and Rhode Island,--sparingly scattered
throughout; Connecticut,--reported from East Hartford, Westville,
Canaan, and Lisbon (J. N. Bishop).
South to Florida and Alabama; west to Dakota, Nebraska, Kansas, and
Missouri.
=Habit.=--Medium-sized to large tree, 30-70 feet high, with trunk 1-3
feet in diameter; erect, branches spreading, broad-headed; in general
appearance resembling the white ash.
=Bark.=--Trunk dark gray or brown, smooth in young trees, furrowed in
old, furrows rather shallower than in the white ash; branches grayish;
young shoots greenish-gray with a rusty-velvety or scurfy pubescence
lasting often into the second year.
=Winter Buds and Leaves.=--Buds rounded, dark reddish-brown, more or
less downy, smaller than those of the white ash, partially covered by
the swollen petiole. Leaves pinnately compound, opposite, 9-15 inches
long; petiole short, downy, enlarged at base; leaflets 7-9, opposite,
3-5 inches long, about one half as wide, light green and smooth above,
paler and more or less downy beneath; outline extremely variable, ovate,
narrow-oblong, elliptical or sometimes obovate, entire or slightly
toothed; apex acute to acuminate; base acute or rounded; leaflet stalks
short, grooved, downy; stipules and stipels none.
=Inflorescence.=--May. Similar to that of the white ash.
=Fruit.=--Ripening in early fall, and hanging in clusters into the
winter; samara or key about 1-1/2 inches long; body of the fruit
narrowly cylindrical, the edges gradually widening from about the center
into linear or spatulate wings, obtuse or rounded at the ends, sometimes
mucronate.
=Horticultural Value.=--Hardy throughout New England; grows readily in
any good soil, but prefers a wet or moist, rich loam; almost as rapid
growing when young as the white ash, and is not seriously affected by
insects or fungous diseases; worthy of a place in landscape plantations
and on streets, but not often found in nurseries; propagated from seed.
