Crataegus ×disperma Ashe. Two-seed Hawthorn. Phen: May; Sep-Oct. Hab: Upland forests, pastures, brushy hillsides. Dist: PA west to IN, south in the Appalachians to VA and e. KY.

Origin/Endemic status: Endemic

Taxonomy Comments: C. disperma is of presumed hybrid origin between C. crus-galli and C. punctata, since characters appear intermediate. It sometimes appears in mixed populations of the putative parent species, but its reproductive biology is poorly known. Similar to other hawthorns of presumed hybrid origin, it may be apomictic but no large local populations are known.

Synonymy: = K3, Tn; = Crataegus disperma Ashe – F, FNA9, Il, Tat, Ashe (1900b), Lance (2014); = n/a – RAB
