=Winter Buds and Leaves.=--Buds ovoid, 1/8-1/4 inch long, obtuse. Leaves

simple, irregularly alternate, often apparently whorled when clustered

at the ends of the shoots, 2-5 inches long, one-half as wide; at first

bright green beneath, dullish-green above, becoming dark glossy green

above, paler beneath, obovate or oblanceolate to oval; entire, few or

obscurely toothed, or wavy-margined above the center; apex more or less

abruptly acute; base acutish; firm, smooth, finely sub-veined; stem

short, flat, grooved, minutely ciliate, at least when young; stipules

none.

=Inflorescence.=--May or early June. Appearing with the leaves in

axillary clusters of small greenish flowers, sterile and fertile usually

on separate trees, sometimes on the same tree,--sterile flowers in

simple or compound clusters; calyx minutely 5-parted, petals 5, small or

wanting; stamens 5-12, inserted on the outside of a disk; pistil none:

fertile flowers larger, solitary, or several sessile in a bracted

cluster; petals 5, small or wanting; calyx minutely 5-toothed.

=Fruit.=--Drupes 1-several, ovoid, blue black, about 1/2 inch long,

sour: stone striated lengthwise.

=Horticultural Value.=--Hardy throughout New England; adapts itself

readily to most situations but prefers deep soil near water. Seldom

offered in nurseries and difficult to transplant unless frequently

root-pruned or moved; collected plants do not thrive well; seedlings are

raised with little difficulty. Few trees are of greater ornamental

value.

EBENACEÆ. EBONY FAMILY.

=Diospyros Virginiana, L.=

PERSIMMON.

=Habitat and Range.=--Rhode Island,--occasional but doubtfully native;

Connecticut,--at Lighthouse Point, New Haven, near the East Haven

boundary line, there is a grove consisting of about one hundred

twenty-five small trees not more than a hundred feet from the water's

edge, in sandy soil just above the beach grass, exposed to the

buffeting of fierce winds and the incursions of salt water, which comes

up around them during the heavy winter storms. These trees are not in

thriving condition; several are dead or dying, and no new plants are

springing up to take their places. A cross-section of the trunk of a

dead tree, as large as any of those living, shows about fifty annual

rings. There is no reason to suppose that the survivors are older. This

station is said to have been known as early as 1846, at which date the

ground where they stand was grassy and fertile. These trees, if standing

at that time, must assuredly have been in their infancy. The

encroachment of the sea and subsequent change of conditions account well

enough for the present decrepitude, but their general similarity in size

and apparent age point rather to introduction than native growth.

South to Florida, Alabama, and Louisiana; west to Iowa, Kansas, and

Texas.

=Habit.=--One of the Rhode Island trees measured 3 feet 11 inches girth

at the base, and gradually tapered to a height of more than 40 feet (L.

W. Russell). The trees at New Haven are 15-20 feet in height, with a

trunk diameter of 6-10 inches, trunk and limbs much twisted by the

winds. Their branches, beginning to put out at a height of 6-8 feet, lie

in almost horizontal planes, forming a roundish, open head.

=Bark.=--Trunk in old trees dark, rough, deeply furrowed, separating

into small, firm sections; large limbs dark reddish-brown; season's

shoots green, turning to brown.

=Winter Buds and Leaves.=--Buds oblong, conical, short. Leaves simple,

alternate, 3-6 inches long, about half as wide, dark green and mostly

glossy above, somewhat lighter and minutely downy (at least when young)

beneath, ovate to oval, entire; apex acute to acuminate; base acute,

rounded or truncate; leafstalk short; stipules none.

=Inflorescence.=--June. Sterile and fertile flowers on separate or on

the same trees; not conspicuous, axillary; sterile often in clusters,

fertile solitary; calyx 4-6-parted; corolla 4-6-parted; about 1/2 inch

long, pale yellow, thickish, urn-shaped, constricted at the mouth and

somewhat smaller in the sterile flowers; stamens 16 in the sterile

flowers, in fertile flowers 8 or less, imperfect; styles 4, ovary

8-celled.

=Fruit.=--A berry, ripe in late fall, roundish, about an inch in

diameter, larger farther south, with thick, spreading, persistent calyx,

yellow to yellowish-brown, very astringent when immature, edible and

agreeable to the taste after exposure to the frost; several-seeded.

=Horticultural Value.=--Hardy along the south shore of New England;

prefers well-drained soil in open situations; free from disfiguring

enemies; occasionally cultivated in nurseries but difficult to

transplant. Propagated from seed.

OLEACEÆ. OLIVE FAMILY.

Fraxinus Americana, L.

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 tall 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.

=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.

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.

=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.)

_Cratægus 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.)
