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 ...
Cones are 5–9 cm (2– 3 + 1 ⁄ 2 in) long, with thin, fragile scales; they are dark blue-purple before maturation, turning brown when ripe about 16–18 months after pollination. The 6–7 mm ( 1 ⁄ 4 – 9 ⁄ 32 in) long seeds have a 2–2.5 cm ( 3 ⁄ 4 –1 in) wing and are wind- dispersed .
Mature open cones and seeds Roots of an old pine in Ystad, Sweden. The seed cones are red at pollination, then pale brown, globose and 4–8 mm (5 ⁄ 32 – 5 ⁄ 16 in) in diameter in their first year, expanding to full size in their second year, pointed ovoid-conic, green, then gray-green to yellow-brown at maturity, 3–7.5 cm (1 + 1 ⁄ 8 –3
The cones are ovoid, 4–7 cm (1 + 5 ⁄ 8 – 2 + 3 ⁄ 4 in) long, chestnut-brown, opening when mature in late winter to 4–6 cm (1 + 5 ⁄ 8 – 2 + 3 ⁄ 8 in) broad. The seeds are winged, 4–6 mm (5 ⁄ 32 – 1 ⁄ 4 in) long with a 10–15 mm (3 ⁄ 8 – 9 ⁄ 16 in) wing. Pollination occurs in mid-spring, with the cones maturing 18 ...
The almost round cones are 5–8 cm (2– 3 + 1 ⁄ 4 in) long with small prickles on the scales. Its cones are usually serotinous, requiring fire to open. [6] The pollen cones are cylinder-shaped with a yellow, brownish color, and are up to 1.8 inches long. Seed cones need two years to mature after pollination.

The female cone then opens, releasing the seeds which grow to a young seedling. To fertilize the ovum, the male cone releases pollen that is carried in the wind to the female cone. This is pollination. (Male and female cones usually occur on the same plant.) The pollen fertilizes the female gamete (located in the female cone).
P. e. var. densa (South Florida slash pine, Dade County pine) is found in the pine rocklands of southern Florida and the Florida Keys, including the Everglades. [10] [11] Leaves are nearly all in bundles of two, with longer needles. The cones are smaller, 5–12 cm (2.0–4.7 in), the wood is denser, and the tree has a thicker taproot. [9]
