=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.

=Fraxinus Pennsylvanica, Marsh.=

_Fraxinus pubescens, Lam._

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.

=Fraxinus Pennsylvanica, var. lanceolata, Sarg.=

_Fraxinus viridis, Michx. f. Fraxinus lanceolata, Borkh._

GREEN ASH.

River valleys and wet woods.

Ontario to Saskatchewan.

Maine,--common along the Penobscot river from Oldtown to Bangor;
Vermont,--along Lake Champlain; Gardner's island, and the north end of
South Hero; Rhode Island (Bailey); Connecticut,--frequent (J. N. Bishop,
_Report of Connecticut Board of Agriculture_, 1895).

South along the mountains to Florida; west to the Rocky mountains.

The claims to specific distinction rest mainly upon the usual absence of
pubescence from the young shoots, leaves and petioles, the color of the
leaves (which is bright green above and scarcely less so beneath), the
usually more distinct serratures above the center, and a rather more
acuminate apex.

Apparently an extreme form of _F. pubescens_, connected with it by
numerous intermediate forms through the entire range of the species.

Anticosti through Ontario.

Maine,--common; New Hampshire,--south of the White mountains;
Vermont,--common; Massachusetts,--more common in central and western
sections; Rhode Island,--infrequent; Connecticut,--occasional
throughout.

South to Delaware and Virginia; west to Arkansas and Missouri.

=Habit.=--A tall tree reaching a height of 60-80 feet, with a trunk
diameter of 1-2 feet; attaining greater dimensions southward. In swamps,
when shut in by other trees, the trunk is straight, very slender,
scarcely tapering to point of branching, in open situations under
favorable conditions forming a large, round, open head. Easily
distinguished from the other ashes by its sessile leaflets.

=Bark.=--Bark of trunk a soft ash-gray, in old trees marked by parallel
ridges separating into fine, thin, close flakes; limbs light gray,
rough-warted, the smaller with conspicuous leaf-scars; season's shoots
olive green, stout; flattened at apex, with small, black, vertical dots.

=Winter Buds and Leaves.=--Buds roundish, pointed, very dark, the
terminal 1/8 inch long. Leaves compound, opposite, 12-15 inches long;
stipules none; stem grooved and smooth; leaflets 7-11, more frequently
9, 3-5 inches long, 1-1/2-2 inches wide, green on both sides, lighter
beneath and more or less hairy on the veins; outline variable, more
usually oblong-lanceolate, sharply serrate; apex acuminate; base obtuse
to rounded, sessile except the odd leaflets; stipels none.

=Inflorescence.=--May. Appearing before the leaves in loose panicles
from lateral or terminal buds of the preceding season, sterile and
fertile flowers on different trees; bracted; calyx none; petals none.

=Fruit.=--August to September. Samaras, in panicles, rather more than 1
inch long, rounded at both ends: body entirely surrounded by the wing.

=Horticultural Value.=--Hardy throughout New England; grows in any good
soil, but prefers swamp or wet land. Its very tall, slender habit makes
it a useful tree in some positions, but it is not readily obtainable in
nurseries and is seldom used. Propagated from the seed.

Frequent throughout New England.

South along the mountains to Georgia and Kentucky; west to
Minnesota, Nebraska, and Missouri.

=Habit.=--A shrub or small tree, 10-25 feet in height with numerous
branches forming a wide-spreading, compact rounded head; conspicuous by
rich foliage, profuse, fragrant yellowish-white flowers, and long,
drooping clusters of crimson fruit which deepen to a rich purple when
fully ripe.

=Bark.=--Trunk and larger branches dark purplish or reddish brown,
separating in old trees into small, firm sections; branchlets
grayish-brown; season's shoots reddish-brown, dotted, more or less
scurfy.

=Winter Buds and Leaves.=--Leaf-buds long, narrow, covered with scurfy,
brown, leaf-like scales; flower-buds much longer, swollen at the base,
with two leaf-like scales extended into a long, spire-like point. Leaves
simple, opposite, 2-4 inches long, upper surface bright green, lower
paler and set with rusty scales, ovate to oblong-ovate or orbicular,
sharply and finely serrate, smooth, tapered or abruptly pointed; base
acute to rounded or truncate; stem slender, wavy-margined, channeled
above; stipules none.

=Inflorescence.=--May or early June. Terminal, in broad, flat-topped,
compound, sessile cymes; calyx-tube adherent to the ovary, 5-toothed;
corolla white, salver-shaped, segments 5, oval, reflexed; stamens 5,
projecting, anthers yellow; pistil truncate.

=Fruit.=--Profuse, in clusters; drupes 1/2 inch long, oval, crimson when
ripening, deep purple when fully ripe, edible, sweet: stone flat, oval,
rough, obscurely striate lengthwise.

=Horticultural Value.=--Hardy throughout New England; prefers a rich
soil in open places or in light shade. Its showy flowers, healthy
foliage, and vigorous growth make it a desirable plant for high shrub
plantations, and as an undergrowth in open woods. Offered for sale by
collectors and occasionally by nurserymen; easily transplanted;
propagated from seed or from cuttings.

APPENDIX.

The range of several trees as given in the text has been extended by
discoveries made during the summer of 1901, but reported too late for
incorporation in its proper place.

_Populus balsamifera_, L., var. _candicans_, Gray.--One of the commonest
and stateliest trees in the alluvium of the Connecticut and the Cold
rivers; with negundo, river maple, and white and slippery elm, forming a
tall and dense forest along the Connecticut at the foot of Fall
mountain, and opposite Bellows Falls. The densely pubescent petioles and
the ciliate margins of the broad cordate leaves at once distinguish this
tree from the usually smaller but more common _P. balsamifera_ ("Some
Trees and Shrubs of Western Cheshire County, N. H." Mr. M. L. Fernald,
in _Rhodora_, III, 233).

The above is the _Populus candicans_, Ait., of the text.

_Salix discolor_, Muhl.--There are many fine trees at Fort Kent, Maine,
one with trunk 13 inches in diameter. (M. L. Fernald _in lit._,
September, 1901.)

_Salix balsamifera_, Barrett.--A handsome tree at Fort Kent, 25-30 feet
high, with trunk 4-6 inches in diameter. (M. L. Fernald _in lit._,
September, 1901.)

_Crataegus Crus-Galli_, L.--Nantucket, Massachusetts. Young trees were
set out in 1830, enclosing an oblong of about an acre and a half. The
most flourishing of these have obtained a height of about 30 feet and a
trunk diameter near the ground of 10-12 inches. Now established,
probably through the agency of birds, along swamps and upon
hill-slopes. (L. L. D.)

_Prunus Americana_, Marsh.--One clump of small trees in a thicket at
Alstead Centre, N. H., has the characteristic spherical fruit of this
species. _P. nigra_, Ait., with oblong, laterally flattened fruit, is
abundant. (_Rhodora_, III, 234.)

_Acer Saccharum_, Marsh., var. _barbatum_, Trelease.--Characteristic
trees (Cheshire County, N. H.), with small, firm, deep green,
three-lobed leaves, appear very distinct, but many transitions are noted
between this and the typical _Acer Saccharum_. (_Rhodora_, III, 234.)

_Acer Saccharum_, Marsh., var. _nigrum_, Britton.--Occasional in
alluvium of the Cold river (Cheshire county, N. H.). The large, dark
green, "flabby" leaves, with closed sinuses and with densely pubescent
petioles and lower surfaces, quickly distinguish this tree from the
ordinary forms of the sugar maple. (_Rhodora_, III. 234.)

_Fraxinus Pennsylvanica_. Marsh., var. _lanceolata_, Sarg.--Common along
the Connecticut at Walpole, N. H. (M. L. Fernald _in lit._, September,
1901.)
