R. W. Smith
A native of the eastern Mediterranean area, long cultivated in Europe and North America, occasionally seeding in disturbed ground, fencerows, forests, rarely swamps, even surviving until old enough to fruit. First collected in 1900 in St. Clair Co. Doubtless escaped more often than the few existing collections document. Hardy and often planted throughout the Lower Peninsula and into the Upper Peninsula.
Often called “chestnut,” especially in Europe, but that name is misleading, because this species is wholly different from the true chestnut, Castanea of the Fagaceae.
The coarser-looking, obovate leaflets and larger fruit usually suffice to separate this species from A. glabra at a glance.
