Eoginkgoites

Eoginkgoites is an extinct form genus of bennettitalean leaves from the Late Triassic of North America.

[1][2] Despite its palmate (hand-shaped) appearance similar to some early ginkgo species, it belongs to a different gymnosperm order, the Bennettitales.

The leaf is deeply segmented into five to seven narrow, club-shaped lobes (pinnae or leaflets) which twist around a very short rhachis.

The leaf has paracytic stomata (with subsidiary cells laterally flanking the guard cells) and veins which strongly branch and lead to a marginal vein at the edge of each leaflet.

[1][2] Williamsonia carolinensis, an ovule-bearing bennettitalean cone, has been found closely associated with Eoginkgoites leaves, seemingly confirming its benettitalean identity.
