Populus candicans, Ait. Balm of Gilead.

Populus balsamifera, var. candicans, Gray.

Habitat and Range.—In a great variety of soils; usually in cultivated or pasture lands in the vicinity of dwellings; infrequently found in a wild state. The original site of this tree has not been definitely agreed upon. Professor L. H. Bailey reports that it is indigenous in Michigan, and northern collectors find both sexes in New Hampshire and Vermont; while in central and southern New England the staminate tree is rarely if ever seen, and the pistillate flowers seldom if ever mature perfect fruit. The evidence seems to indicate a narrow belt extending through northern New Hampshire, Vermont and Michigan, with the intermediate southern sections of the Province of Ontario as the home of the Balm of Gilead.

New England,—occasional throughout.

Habit.—A medium-sized tree, 40-60 feet high; trunk 1-3 feet in diameter, straight or inclined, sometimes beset with a few crooked, bushy branchlets; head very variable in shape and size; solitary in open ground, commonly broad-based, spacious, and pyramidal, among other trees more often rather small; loosely and irregularly branched, with sparse, coarse, and often crooked spray; foliage dark green, handsome, and abundant; all parts characterized by a strong and peculiar resinous fragrance. A single tree multiplying by suckers often becomes parent 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 1-1½ 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.
