A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like.
The name Pinus coulteri comes from Latin for pine, and coulteri comes from its discoverer Thomas Coulter (1793–1843), an Irish botanist and physician. [9] Pinus coulteri was discovered by Dr. Coulter on the mountains of Santa Lucia, near the Mission of San Antonio, in latitude 36°, within sight of the sea and at an elevation of from 3000 to 4000 feet above its level.
Most conifers are monoecious, but some are subdioecious or dioecious; all are wind-pollinated. Conifer seeds develop inside a protective cone called a strobilus. 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.

The cones are 8–17 cm (3– 6 + 1 ⁄ 2 in) long and 4–6 cm (1 + 1 ⁄ 2 – 2 + 1 ⁄ 4 in) broad, dark purple before maturity; [4] [5] the scale bracts are short, and hidden in the closed cone.
