Coulter pine. P. subsect. Ponderosae. Coulter pine (Pinus coulteri), or big-cone pine, is a conifer in the genus Pinus of the family Pinaceae. Coulter pine is a native evergreen conifer that lives up to 100 years of age. [2] Coulter pine occurs in a mediterranean climate. Winter rains are infrequent, and the summer is dry with occasional summer ...
List of. Pinus. species. Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The genus is currently split into two subgenera: subgenus Pinus (hard pines), and subgenus Strobus (soft pines). Each of the subgenera have been further divided into sections based on chloroplast DNA sequencing [1] and whole plastid genomic ...
Conifer cone. A mature female big-cone pine (Pinus coulteri) cone, the heaviest pine cone. A young female or seed cone on a Norway spruce (Picea abies) Immature male or pollen cones of Swiss pine (Pinus cembra) A conifer cone or, in formal botanical usage, a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially 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 ...
Pinus lambertiana. Douglas. Natural range of Pinus lambertiana. Pinus lambertiana (commonly known as the sugar pine or sugar cone pine) is the tallest and most massive pine tree, and has the longest cones of any conifer. The species name lambertiana was given by the Scottish botanist David Douglas, who named the tree in honour of the English ...

Description. Araucaria columnaris is a distinctive narrowly conical tree growing up to 60 m (200 ft) tall in its native habit. The trees have a slender, spire-like crown. [3] The shape of young trees strongly resembles A. heterophylla. The bark of the Cook pine peels off in thin paper-like sheets or strips and is rough, grey, and resinous. [3]
The pine cones of the tree resemble the cones of the Siberian pine (P. sibirica). The cones are larger and thicker and not as much elongated as Japanese stone pine (P. pumila) cones. On average the cones are 4 cm long and 3 cm wide. Each cone contains 40 nut-like seeds. Seeds are on average 8 mm long. Only about 15% (at most) of the seeds in ...
