ROSACEAE

Crataegus macrosperma Ashe. Eastern Hawthorn. Phen: Apr-early May; Sep-Oct. Hab: Mesic to subxeric hardwood forests, wooded slopes, rock outcrops, pastures, thickets, mountain balds and rocky summits. Dist: ME to MN, south to GA, AL, AR; C. macrosperma is widespread, particularly common in the Appalachians.

ID notes: C. macrosperma is consistent in its adaxially lightly scabrous-pubescent young leaves, 5-10 stamens, and soft-textured mature fruit. The pyrenes are not unusually large (5-8 mm), so the epithet is somewhat a misnomer.

Origin/Endemic status: Native
