乔木，在原产地高达40米；树皮淡栗褐色，纵裂成鳞状块片，树干上常有不定芽萌生出许多针叶；枝条每年生长多轮，小枝较细，暗红褐色，初被白粉；芽矩圆状卵圆形，褐色，无树脂。针叶2-3针一束，长5-12厘米，较细，径微不及1毫米，深蓝绿色；横切面半圆形或三角形，单层皮下层细胞，稀有散生细胞的第二层，树脂道2-5，中生或其中1-3个内生。球果圆锥状卵圆形，长4-6厘米，具短梗或几无梗，熟时种鳞张开；种鳞的鳞盾平或微肥厚，暗褐色，鳞脐突起，有极短之刺。
原产北美。我国江苏南京、浙江富阳、福建闽侯有栽培，生长较快，为有发展前途的造林树种。

Pinus echinata Miller
萌芽松 meng ya song
Trees to 40 m tall; trunk to 1.2 m d.b.h. in native range, usually with adventitious sprouts; bark red-brown, plates scaly with evident resin pockets; crown rounded-conical; 2nd-year branchlets greenish brown or red-brown, aging red-brown or gray, slender, to 5 mm in diam., roughened and cracking below leafy portion; winter buds red-brown, ovoid or cylindric, resinous. Needles 2 (or 3) per bundle, gray- or yellow-green, straight, slightly twisted, (5-)7-11(-13) cm × ca. 1 mm, stomatal lines present on all surfaces, base with persistent sheath 0.5-1(-1.5) cm. Seed cones solitary or clustered, subsessile or shortly pedunculate (peduncle to 1 cm), red-brown, aging gray, ovoid-conical when open, 4-7 cm, maturing in 2 years. Seed scales lacking contrasting dark border adaxially distally; umbo with an elongated or stout and short, sharp prickle. Seeds gray or nearly black, ellipsoid, ca. 6 mm; wing 1.2-1.6 cm.
Cultivated. Fujian (Minhou Xian), Jiangsu (Nanjing Shi), Zhejiang (Fuyang Xian) [native to SE United States]
This tree is very fast growing and is highly valued as a source of timber and wood pulp. It is also a promising species for afforestation.
