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).
The trees are mostly dioecious, with male and female cones found on separate trees, [4] though occasional individuals are monoecious or change sex with time. [5] The female cones, usually high on the top of the tree, are globose , and vary in size among species from 7 to 25 centimetres (3 to 10 in) in diameter.
Female cones of C. equisetifolia. 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.
The prothallium developed from the spore is a subterranean mass of tissue of considerable size, and bears both the male and female organs (antheridia and archegonia). [6] They are more commonly distributed vegetatively, though, through above- or below-ground rhizomes .
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), and have a small, but sharp, downward-pointing spine on the middle of each scale.
