A mature female big-cone pine (Pinus coulteri) cone, the heaviest pine cone A young female cone on a Norway spruce (Picea abies) Immature male 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 conifers and cycads.
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 ...
Casuarina, also known as she-oak, Australian pine [3] [4] [5] and native pine, [6] is a genus of flowering plants in the family Casuarinaceae, and is native to Australia, the Indian subcontinent, Southeast Asia, islands of the western Pacific Ocean, and eastern Africa.
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 ...
The cones are broad, ovoid, 8–15 cm (3–6 in) long, and take 36 months to mature, longer than any other pine. The seeds ( pine nuts , piñones , pinhões , pinoli , or pignons ) are large, 2 cm ( 3 ⁄ 4 in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 4–8 mm ( 5 ⁄ 32 – 5 ⁄ 16 in ...
Like all conifers, the mountain pine life cycle is dependent on cones. Male and female flowers are found on separate trees [4] – male cones 3-5mm long are at the tips of branches [18] and female flowers grow solo or in pairs and form just below the tips of the branches. [4]
Table Mountain pine typically has long, thick limbs on much of the trunk even in closed canopy stands. [7] Male cones are 1.5 centimetres (0.59 in) long. Female cones are sessile and range from 4.2 to 10 centimetres (1.7 to 3.9 in) long. [7] Cone scales are tough and armed with broad, upwardly curving spines. [6]
