The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which when fertilized by pollen become seeds. The female cone structure varies more markedly between the different conifer families and is often crucial for the identification of many species of conifers.
The cones develop from axillary buds, and may be solitary or form clusters. [1] The pollen cones are long and catkin-like in shape. They may be sessile or short pedunculate. A pollen cone consists of a slender rachis with numerous spirally arranged microsporophylls around it. Each triangular microsporophyll has two basal pollen-producing pollen ...

The male pollen cones may be axillary or terminal and solitary or grouped. They have glabrous peduncles. A pollen cone consists of many spirally arranged microsporophylls each with two pollen sacs producing bisaccate pollen. [1] The female seed cones develop from axillary buds. They are often solitary but may also be paired.
The cones are globose to oval, 1–3 cm diameter, with 15-35 scales, each scale with 3-6 seeds; they are mature in 7–9 months after pollination, when they open to release the seeds. The male (pollen) cones are small, and shed their pollen in early spring.
