(1) In this case, ‘cone’ is a colloquial term for a woody strobilus .(2) Note that this is a strobilus with possible homology to the ovule-bearing cone of conifers.(3) While many lycophytes have their sporophylls scattered along their stem, most produce them in a strobilus .(4) Unlike most seed plants, however, the pollen and ovule-bearing organs are usually produced together in a bisporangiate strobilus called a flower.(5) At the tips of reproductive branches are the ‘cones,’ or strobili , which consist of tightly packed appendages called sporangiophores.(6) The microsporophylls of cycads are arranged in strobili and bear clusters of microsporangia on their abaxial surface.(7) Immature female and male strobili cones were harvested from a 40-year-old Norway spruce tree, 2 weeks prior to pollen release.
