Pinus ponderosa var. pacifica J.R. Haller & Vivrette
Stem: mature bark light to medium yellow-brown. Leaf: 15--28 cm, thin, not glaucous, deep green, shiny, not glaucous; sheath persistent?. Seed Cone: generally 8--18 cm, generally ovate, when immature light yellow-green, maturing closed cones green; scales black abaxially, brown adaxially, in open cone well separated; distal knob prickles generally outcurved. Seed: +- 1/3--1/5 wing.
Ecology: Coastal-draining slopes of major mountain ranges, streambanks; Elevation: 100--2700 m. Bioregional Distribution: NCoR, CaR, SN, SnFrB (Santa Cruz Mtns), TR, PR; Distribution Outside California: southwestern Oregon, Washington. Note: Some very large-coned plants in Santa Cruz Mountains, unassigned taxonomically in this treatment, may be indistinct from var. pacifica (then the earlier var. benthamiana (Hartw.) Vasey would be correct for the unassigned pls, with var. pacifica as a synonym), or may be a distinct var. within P. ponderosa (then var. benthamiana would be correct for the unassigned plants), or may be a distinct species (then P. benthamiana Hartw. would be correct for the unassigned plants); study needed.
Synonyms: Pinus benthamiana Hartw.; Pinus ponderosa Douglas ex Lawson & C. Lawson subsp. benthamiana (Hartw.) Silba; Pinus ponderosa Douglas ex Lawson & C. Lawson var. benthamiana (Hartw.) Vasey
