 Pollen strobili consist of microsporophylls, each of which may have dozens or hundreds of abaxial microsporangia.The single living member of the Ginkgophyta, "Ginkgo biloba" produces pollen strobili, but the ovules are typically borne in pairs at the end of a stem, not in a strobilus.When there are more than a pair of ovules in "G. biloba", however, or when fossil taxa bearing large numbers of ovules are examined, it is clear that the paired ovules in the extant species are a highly reduced strobilus.
