Pinus prominens Masters; P. sinensis D. Don var. densata (Masters) Shaw; P. tabuliformis Carriere var. densata (Masters) Rehder; P. wilsonii Shaw (1911); not Roezl (1857).
Trees to 30 m tall; trunk to 1.3 m d.b.h.; bark reddish brown; scaly and plated when young; finally dark grayish brown; forming irregular; square; thick plates; crown ovoid-conical; broadly ovoid in old trees; branches spreading; 1st-year branchlets shiny yellowish brown; stout; 2nd- and 3rd-year branchlets reddish brown; winter buds dull brown; ovoid-conical; ca. 15 x 6 mm; slightly resinous; scales white fringed at margin; acuminate at apex. Needles persisting for 3 years; usually 2(or 3) per bundle; straight; slightly twisted; 8-14 cm x 1-1.5 mm; stomatal lines present on all surfaces; resin canals 3 or 4; marginal; occasionally 1 or 2 median; base with persistent sheath initially 5-10 mm; margin finely serrulate; apex acute. Pollen cones yellowish brown; cylindric; 10-18 x 3-4.5 mm. Seed cones solitary or in pairs; pendulous; sessile or very shortly pedunculate; shiny chocolate brown at maturity; narrowly ovoid before opening; ovoid or broadly ovoid when open; 4-6 x 4-7 cm; persistent. Seed scales with apophyses prominent; rhombic; 4-7 mm thick; sharply transversely keeled; umbo dorsal; with a short prickle. Seeds light grayish brown; ellipsoid-ovoid; 4-6 mm; wing 1.5-2 cm. Pollination May; seed maturity Oct of 2nd year.
