Celtis occidentalis - Hackberry
 Can get up to 60 feet tall.
 
 
  This tree is very adaptable to various site conditions; however, insects tend to be problematic.  Most Hackberries I've encounter are attacked by insects that cause tissues of the leaf to swell.  These swellings/bumps on the leaves are known as Leaf Nipple Galls which are caused by Psyllid insects.
 Mature bark has vertical corky rows which criss-cross.
 Leaves are simple and attached alternately.
 
  Base of leaves are uneven.
 
  Leaves are serrate except for at the base of the leaf.
 
  Fruit is called a drupe (berry) red to dark red.
