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 cones take from four months to three years to reach maturity, and vary in size from 2 to 600 millimetres (1 ⁄ 8 to 23 + 5 ⁄ 8 in) long. In Pinaceae, Araucariaceae, Sciadopityaceae and most Cupressaceae, the cones are woody, and when mature the scales usually spread open allowing the seeds to fall out and be dispersed by the wind.
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 ...
Pinus aristata is a medium-size tree, commonly reaching 15 meters (49 ft) in height and occasionally as much as 20 m (66 ft) in their natural habitat. In favorable conditions they are straight and upright trees, but they become increasingly stunted, short, and twisted the closer they grow to timberline. [4] The crown of the tree is flattened ...
A pine is any conifer tree or shrub in the genus Pinus (/ ˈpaɪnəs /) [1] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. World Flora Online accepts 187 species names of pines as current, with additional synonyms, making it the largest family among the conifers. [2]

Sugar pine is notable for having the longest cones of any conifer, mostly 10–50 cm (4– 19 + 3 ⁄ 4 in) long, [2] [5] exceptionally to 60 cm (23 + 1 ⁄ 2 in) long [citation needed] (although the cones of the Coulter pine are more massive); their unripe weight of 1–2 kilograms (2.2–4.4 lb) makes them perilous projectiles when chewed off ...
