Seeds of pinups gerardiana chilgoza are edible. A well developed flower like that of angiosperms is absent in Cycas. The genus cycas is the most widely distributed genus of the order cycadales. They produce different spores, which are the haploid microspores and megaspores. They have naked seeds, in contrast to the seeds or ovules of flowering plants (angiosperms) which are enclosed during pollination.Gymnosperm seeds develop either on the surface of scale- or leaf-like appendages of cones, or at the end of short stalks (Ginkgo).
