is composed of numerous forking veins which start at the base of the leaf. This forking is different from the vein structure of G. biloba in which all the veins fork from a single vein along the edge of the blade. The overall vein density in G. dissecta is 12–14 veins per centimeter, which is lower than the reported average of 16–17 veins per centimeter in G. biloba. G. dissecta is superficially similar to the older species G. digitata and G. huttonii known from Jurassic fossils. However, both G. digitata and G. huttoni have leaves which are typically divided into six lobes rather than four and both of them have distinct trichomes, hairs, on the underside of the leaves.
