I need help finding scientific names for these plants.?

Note:These are all from Southern New York (or Eastern United States)





*Purple Cone Flower


*Buddleja (Butterfly bush)


*Cedar


*Wild Cherry


*Crimson Glow Maple


*Burdock (I know it begins with Arctium, but I don't know the species)





The person who gets all (or most) of them correct will get 10 points (or how ever many points it is if you get best answer) by tommorow night.





Thanks to everyone in advance!
