Conifer seeds are produced in tiny scale-like things called seed cones or ovulate cones. These are completely different from the yellow, wormlike, pollen-producing cones you shook next to your car. At pollination time, seed cones are so small and inconspicuous that most people never notice them.
The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to species.Extending out from a central axis are microsporophylls (modified leaves).ale cones of a pine A classic example of a Lebanese Cedar cone.
