Genus CN: pawpaw
Genus Authority: Adans.
Genus Summary: A genus of about 12 species of shrubs and small trees, endemic to e. North America. Here circumscribed to include Deeringothamnus of peninsular FL; if the genus is to be split into two, the warranted split would be as done by J.K. Small (1933), with Asimina confined to A. triloba and A. parviflora, and all other species, including Deeringothamnus, placed in a second genus. Four additional species occur south of our area in the FL peninsula: A. manasota DeLaney, A. pulchella (Small) Rehder & Dayton, A. rugelii B.L. Robinson, and A. tetramera Small. It is likely that additional taxa will be named.
Genus Identification: Identification notes: Hybrids are known between some of the pineland species, notably A. angustifolia ◊ incana [= A. ◊nashii Kral], and should be expected where two species are present. These hybrids are named as binomials and further discussed in DeLaney (2010)
Genus References: DeLaney (2010)=V; Kral (1960)=Z; Wilbur (1970a)=Y; Godfrey (1988)=X; Kral in FNA (1997); Ward (2001); Kessler in Kubitzki, Rohwer, & Bittrich (1993).
