Flowers n -veins in most are parallel. This is partly because homoplasy is very common, in addition, basic information for all too many characters is very incomplete, frequently coming from taxa well embedded in the clade of interest and so making the position of any putative apomorphy uncertain.

Characters mentioned are those of the immediate common ancestor of the group,  contains explanatory material, features common in clade, exact status unclear. About project SlidePlayer Terms of Service. Dioecy may be associated with chromosomal differentiation female xx, male xybut c.
With its long generation time, great longevity and large seeds it hardly fits current ideas of plants that flourish in such habitats, but conditions in the early Cretaceous may have been quite different from those of today Royer et al.
There may have been a genome duplication here m. For the phylogeography of Ginkgo bilobasee Gong et al. For the early Caenozoic fossil history of Ginkgosee Manchester et al. Thrip pollination of Ginkgoaceae is reported from the Albian ca m. Many of the bolded characters in the characterization above are apomorphies of more or less inclusive clades of streptophytes along the lineage leading to the embryophytes, ginkgoaceas apomorphies of crown-group embryophytes per se.
Ginkgoales and relatives have a long and rich fossil record dating back to the later Permian Z. They were almost world-wide in distribution and included several genera in the Mesozoic. For additional information, see the papers in Hori et ginkgoaceze. We think you have liked this presentation.

Then there are the not-so-trivial issues of how character states are delimited and ancestral states are reconstructed see above.
