Answer: Without seeing the tree and its flowers, it's difficult to positively identify it. However, most species of the hawthorne have very prominent, long, straight, sharp thorns, ranging from 1 to 5 inches in length. There are only a few species without thorns. A hawthorn is the state flower of Missouri so when your tree blooms you can compare the flower clusters online (www.50states.com/flower/missouri.htm).
Best wishes with your tree!
