rent of
a grove covering half an acre, more or less, made up of trees of all
ages and sizes.

=Bark.=--Bark of trunk and lower portions of large branches dark gray,
rough, irregularly striate and firm in old trees; in young trees and
upon smaller branches smooth, soft grayish-green, often flanged by
prominent ridges running down the stalk from the vertices of the
triangular leaf-scars; season's shoots often flanged, shining reddish or
olive green, with occasional longitudinal gray lines, viscid.

=Winter Buds and Leaves.=--Buds dark reddish-brown, rather closely set
along the stalk, conical or somewhat angled, narrow, often falcate,
sharp-pointed, resinous throughout, viscid, aromatic, exhaling a
powerful odor when the scales expand, terminal about 3/4 inch long.
Leaves 4-6 inches long and nearly as wide, yellowish-green at first,
becoming dark green and smooth on the upper surface with the exception
of a _minute pubescence along the veins_, dull light green beneath,
finely serrate with incurved glandular points, usually ciliate with
minute stiff, whitish hairs; base heart-shaped; apex short-pointed;
petioles about 1-1-1/2 inches long, _more or less hairy_, somewhat
flattened at right angles to the blade; stipules short, ovate, acute,
soon falling.

=Inflorescence.=--Similar to that of _P. balsamifera_.

=Fruit.=--Similar to that of _P. balsamifera_.

=Horticultural Value.=--Hardy throughout New England; has an attractive
foliage and grows rapidly in all soils and situations, but the branches
are easily broken by the wind, and its habit of suckering makes it
objectionable in ornamental ground; occasionally offered by nurserymen
and collectors. Propagated from cuttings.

=Range.=--Widely distributed in the Old World, extending in Europe from
southern Sweden to the Mediterranean, throughout northern Africa, and
eastward in Asia to the northwestern Himalayas. Introduced from England
by the early settlers and soon established in the colonial towns, as in
Plymouth and Duxbury, on the western shore of Massachusetts bay. Planted
or spontaneous over a wide area.

New Brunswick and Nova Scotia,--occasional.

New England,--occasional throughout, local, sometimes common.
