''Ptelea'' is a genus of
flowering plants in the citrus family,
Rutaceae. The name, of Greek derivation, is the classical name of the
elm tree.
Carl Linnaeus used that word for this genus because of the resemblance of its fruit to that of the elm.
Members of the genus are commonly known as hoptrees.
