We believe that Wisteria and Snapdragon are related because they are both monocolpate, while tulip pollen is monolete. Since Tulip pollen does not share the same pollen type we gave it its own branch, while Wisteria and Snapdragon share a branch since their pollen types are the same. We observed that Wisteria and Snapdragon pollen also share an oval football-like shape as opposed to Tulip pollen which looks more circular and crinkled. Tulips have one flower per stem, unlike Wisteria and Snapdragon who have multiple flowers per stem, thus we believe that Snapdragon and Wisteria are more closely related to each other than Tulip is related to either species.
