Inflorescence.—June. Sterile flowers at the base of the season's shoots, clustered, oblong-rounded: fertile flowers along the sides or about the terminal buds of the season's shoots, single, in twos or in clusters; bracts ovate, roundish, purplish.
Fruit.—Cones often numerous, 1-2 inches long, pointing in the general direction of the twig on which they grow, frequently curved at the tip, whitish-yellow when young, and brown at maturity; scales when mature without prickles, thickened at the apex; outline very irregular but in general oblong-conical. The open cones, which are usually much distorted, with scales at base closed, have a similar outline.
Horticultural Value.—Hardy in New England; slow growing and hard to transplant; useful in poor soil; seldom offered by nurserymen or collectors. Propagated from seed.
