Note: Ginkgo is often mistakenly thought to have parallel veins. This is incorrect as the veins divide as they branch out to the leaf edge (dichotomous).



Leaf Veins: Parallel

Veins run the length of the leaf roughly evenly apart. In some species, the parallel veins join together at the base and apex. Needle-type evergreens and grasses have parallel veins.
