Yes, ginkgo leaf veins can join together. While the venation pattern in Ginkgo biloba is primarily characterized as dichotomous—meaning the veins branch into two—this system is often described as an "open" type, which is typically devoid of vein fusions. However, it has been shown that vein unions can occur with some regularity in these leaves.1
