Pawpaw

Pawpaw (Asimina triloba /Annonaceae).The genus Asimina is composed of about 8 species native to eastern North America. It flowers early (March – April) and grows best in rich woods at low elevations. Also known as papaw, it is a shrub to small tree reaching heights of 36 feet with diameters of less than 1 foot. This is not a commercial lumber species and thus, no technical information is available on the properties of the wood. The wood is light in weight, has a yellowish tinge and a coarse grain.

Characteristics found in the Pawpaw (Asimina triloba)

  • Ring Porous
  • Coalesced/Confluent parenchyma
  • Simple perforations
  • I/V pits small to medium (4-12)
  • Rays 5-14 seriate & heterocellular
