Editing Ginkgoales (section)

== Reproduction ==
''Ginkgo'' trees produce ovulate and pollen-bearing structures. These structures are [[dioecious]], in that male and female structures come from different ''Ginkgo'' plants.<ref name=":1" /> The pollen organs are very similar to angiospermous [[catkins]]. They come from the [[axils]] of the bud scales, and the leaves from the ''Ginkgo'' tree spur shoots. Pollen is contained in sacs of two to four at the tips of sporophylls on the strobiloid. Ovules of ''Ginkgo'' trees come from stalks from leaf axils on the short shoots, each containing two ovules. The ovule is fertilized by the flagellated male gametes, which can move about freely. This fertilization process begins on the tree itself in the spring. The swollen fruit-like [[ovules]], about 2–3&nbsp;cm in diameter, fall from the tree in the fall, and fertilization continues into the winter/spring.<ref name=":0" /><ref name=":2" />  This ovule contains a single large seed, similar to that of a [[cycad]].<ref name=":0" />
