Family: Anonaceae-The Custard Apple Family

Description: Asimina (Pawpaw) The Pawpaw is a small, deciduous tree that may grow 5-10 meters high (Layne, 1996) and exists in clumps or thickets. According to Duncan and Duncan, the trees are typically a "pyrimidal shape, straight trunk, and dark green, long, drooping leaves" (Duncan and Duncan, 1988). Pawpaws exist as either shrubs or trees, with fruits being "irregularly, cylindrical-shaped berries" (Duncan and Duncan, 1988). Asimina is the only member of the Anonaceae family existing in temperate North America, mostly in the southeast, and the others existing in more tropical climates (Takhtajan, 1997).
