Introduction
Nash pawpaw (Asimina × nashii) is the natural hybrid between A. angustifolia and A. incana. Kral recognized the hybrid in his 1960 revision, and it remains accepted by modern taxonomic databases. Weakley’s southeastern flora reports it as rare in the area of parental overlap and known from eastern Georgia. Tree TSAR places it under Interclade Hybrids because its parents are assigned to different infrageneric clades. (Kral, 1960; Weakley, 2023).
Horticultural and Agricultural Uses
The hybrid has no established agricultural role. It may be encountered or maintained in specialized native-plant collections, but published cultivation information specific to A. × nashii is limited.
Conservation Concerns
No formal conservation assessment was located for the hybrid itself. Its rarity appears to reflect the limited overlap and hybridization of its parents rather than an independently assessed species-level decline.
