Description:  "Trees to 46 m; trunk to 1.6 m in diameter, usually straight, without adventitious shoots; crown broadly conic to rounded. Bark red-brown, forming square or irregularly rectangular, scaly plates, resin pockets absent. Branches spreading-ascending; twigs moderately slender (to ca. 1 cm thick), orangish to yellow-brown, aging darker brown, rough. Buds lance-cylindric, pale red-brown, 1-1.2 (-2) cm, mostly less than 1 cm broad, slightly resinous; scale margins white-fringed, apex acuminate. Leaves 2-3 per fascicle, ascending to spreading, persisting 3 years, (10-) 12-18 (-23) cm x 1-2 mm, straight, slightly twisted, pliant, deep yellow-green, all surfaces with narrow stomatal lines, margins finely serrulate, apex acute to abruptly conic-subulate; sheath 1-2.5 cm, base persistent. Pollen cones cylindric, 20-40mm, yellow to yellow-brown. Seed cones maturing in 2 years, shedding seeds soon thereafter, not persistent, solitary or in small clusters, nearly terminal, symmetric, lanceoloid before opening, narrowly ovoid when open, 6-12 cm, mostly dull yellow-brown, sessile to nearly sessile, scales without dark border on adaxial surface distally; apophyses dull, slightly thickened, variously raised (more so toward cone base), rhombic, strongly transversely keeled; umbo central, recurved, stoutly pyramidal, tapering to stout-based, sharp prickle. Seeds obdeltoid; body 5-6mm, red-brown; wing to 20mm"  (Flora of North America).

Habitat/ecology:  In New Zealand, "logged, burnt and waste land around plantations"  (Webb et al., 1988; p. 59).  In it's native range in the United States, "mesic lowlands and swamp borders to dry uplands; 0-700 m"  (Flora of North America).

Propagation:  Seed

Native range:  Eastern and southeastern United States, cultivated elsewhere (GRIN).
