Editing Ginkgoales (section)

=== Ginkgophyte foliage ===
''Ginkgophyte'' [[foliage]] has stayed largely consistent since the [[Mesozoic]].  Its historically wide territory makes it an important leaf morphology, and its unique [[stomata]] and isotopic profile give it a key role in recreations of the Mesozoic and [[Cenozoic]].  Leaf fossils that resemble the Ginkgophytes are known as ''[[Ginkgoites]]''.  There are similar, now extinct, morphogens, such as ''Sphenobaiera'', which describes fan-shaped, deeply divided leaves without clear [[petiole (botany)|petiole]]s.

The distinctive shape of the modern ''Ginkgo biloba'' gives the impression of a very narrow leaf morphology, but the group is varied and diverse.  The genus ''Ginkgo'' by itself contains a range of morphologies.  ''Ginkgo digitata'', from the [[Jurassic]], has long, wedge-shaped [[lamina (leaf)|lamina]]e with the intercostal regions covered in stomata and resin bodies, while ''G. pluripartita'' has at most 2&nbsp;cm-long leaves and is intercostally [[hypostomatic]].<ref name=":0" />
