Pinus thunbergii (Syn: Pinus thunbergiana; English: Japanese Black Pine, Japanese Pine, Black Pine)

Japanese Black Pine can reach the height of 40 m, but rarely achieves this size outside its natural range. The needles are in fascicles of two with a white sheath at the base, 7-12 cm long; female cones are 4-7 cm in length, scaled, with small points on the tips of the scales, taking two years to mature. Male cones are 1-2 cm long borne in clumps of 12-20 on the tips of the spring growth. Bark is gray on young trees and small branches, changing to black and plated on larger branches and the trunk; becoming quite thick on older trunks.

Pinus thunbergii, Pari. (P. Massoniana, Sieb. & Zucc., not Lamb.). Japanese Black Pine. Tree, to 100 ft., or occasionally 120 ft., with spreading, often somewhat pendulous branches, forming a broad, pyramidal head:branchlets orange-yellow, the winter buds oblong, grayish or silvery white: lvs. stiff, sharply pointed, bright green,3-4 1/2 in. long: cones short-stalked, conic- ovate, grayish brown, 2-3 in. long; apophysis flattened, with small, depressed umbo, obtuse or with a minute prickle; seed grayish brown, 1/4 in. long. Japan.—Handsome tree and hardy N. Several horticultural varieties have been intro. from Japan: one of the most distinct is var. Oculus-draconis, Mayr, each lf. being marked with 2 yellow bands and therefore the tufts of the lvs. at the end of the branches, if seen from above, show alternate yellow and green rings, hence the name Oculus-draconis (dragon-eye). Var. variegata, Hort., has the lvs. partly yellow or occasionally wholly yellowish white. There are also similar forms in P. densiflora, which may be distinguished by the brown color of the winter buds. CH The above text is from the Standard Cyclopedia of Horticulture.
