Bristlecone pine

Bristlecone pines (Pinus aristata, P. longaeva, P. balfouriana), subsection Balfourianae, are high-elevation western North American pines; Great Basin bristlecone holds the oldest non-clonal tree record at about 4,850 to 5,000 years.

Pine

Pine (Pinus) is a large Northern Hemisphere conifer genus of about 175 species, defined by needle fascicles and woody seed cones; notable for 128-million-year-old lineage, fire-adapted serotinous cones, bristlecone longevity, and resin, timber, and edible-seed uses.

Pine nut

Pine nuts, also called pinyon nuts or pignolia, are edible gymnosperm seeds of pines such as Pinus pinea, P. koraiensis, P. sibirica, and P. edulis; not true nuts, wild-harvested, high in oil, and linked to pine mouth from P. armandii.

Pine tar

Pine tar, a wood tar from destructive distillation of Scots pine heartwood, used since antiquity as wood preservative, ship caulking, stave church coating, and topical antiseptic skin treatment.

Pinus cembra

Pinus cembra (Swiss stone pine, arolla pine, Arve, Zirbelkiefer) is an alpine Pinaceae tree of the Alps and Carpathians at 1,500–2,400 m, often forming the tree line, whose wingless seeds are dispersed almost solely by the spotted nutcracker.

Pinus contorta

Pinus contorta, commonly known as lodgepole pine, is a pine tree native to western North America, with one of the region's broadest ranges, from Alaska to northern Baja California and east to South Dakota.

Pinus densiflora

Pinus echinata

Pinus echinata, shortleaf pine, also called southern yellow or old field pine, is a native southeastern US conifer with the widest range of any pine there, valued for timber and adapted to fire by basal sprouting, declining under fire exclusion.

Pinus edulis

Pinus edulis, the twoneedle or Colorado pinyon, is a small drought-hardy pine of the southwestern United States, two needles per fascicle, wingless edible seeds, dominant in pinyon-juniper woodland.

Pinus gerardiana

Pinus gerardiana (chilgoza pine, Jalghoza) is a Near Threatened Himalayan pine of Afghanistan, Pakistan, India and Tibet, grown for large edible wingless seeds selling at USD 20–100/kg, with natural regeneration in only ~5% of its range.

Pinus glabra

Pinus glabra (spruce pine, cedar pine, Walter pine) is a shade-tolerant medium pine of the southeastern US Coastal Plain, native from South Carolina to Louisiana, with smooth gray bark, two-needle fascicles, small cones, and brittle wood of limited commercial value.

Pinus hartwegii

Pinus hartwegii (Hartweg's pine, ocote, pino de las alturas) is a high-elevation Mexican and Central American pine forming monotypic forests to 4,389 m, fire-adapted, IUCN Least Concern, with habitat predicted to shrink up to 70% by 2070.

Pinus jeffreyi

Pinus jeffreyi, Jeffrey pine, is a large California-centered conifer of dry, infertile montane sites, named for John Jeffrey, with heptane-rich resin and high fire resistance as an adult.

Pinus koraiensis
