   Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae.Coulter pine is an evergreen conifer that lives up to 100 years. [2] It is a native of the coastal mountains of Southern California in the United States and northern Baja California in Mexico, occurring in mediterranean climates, where winter rains are infrequent and summers are dry with ...

   en.wikipedia.org/wiki/Closed-cone_conifer_forest

   The most widespread naturally of the closed-cone pines is bishop pine (Pinus muricata), which can be found along the coast from Humboldt County, California in the north to the northwestern corner of Baja California in the south. Knobcone pine (Pinus attenuata) forests can occur further inland, on dry, rocky soils. Monterey pine (Pinus radiata ...

4. Longleaf pine - Wikipedia

   Pollination occurs early the following spring, with the male cones 3–8 cm (1 + 1 ⁄ 4 – 3 + 1 ⁄ 4 in) long. The female (seed) cones mature in about 20 months from pollination; when mature, they are yellow-brown in color, 15–25 cm (6– 9 + 3 ⁄ 4 in) long, and 5–7 cm (2– 2 + 3 ⁄ 4 in) broad, opening to 12 cm ( 4 + 3 ⁄ 4 in ...

   The female cones are large and usually woody, 2–60 centimetres (1–24 inches) long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, 0.5–6 cm (1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some ...

7. Pinus muricata - Wikipedia

   en.wikipedia.org/wiki/Pinus_muricata

   The cones are strongly reflexed down the branch, 5-to-10-centimetre-long (2.0 to 3.9 in) long; the scales are stiff, thin on the side of the cone facing the stem, but greatly thickened on the side facing away and with a stout 5 to 12 millimetres (0.20 to 0.47 in) spine; both features adaptive to minimise squirrel predation and fire damage to ...

8. Abies concolor - Wikipedia

   en.wikipedia.org/wiki/Abies_concolor

   The cones are 6–12 cm (2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 in) long and 4–4.5 cm (1 + 5 ⁄ 8 – 1 + 3 ⁄ 4 in) broad, green or purple ripening pale brown, with about 100–150 scales; the scale bracts are short, and hidden in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 6 months after pollination. [9]

9. Methuselah (pine tree) - Wikipedia

   en.wikipedia.org/wiki/Methuselah_(pine_tree)

   A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
