Genus name comes from a French provincial name for Amelanchier ovalis a European plant in this genus.
Species name honors Jean Baptiste Antoine Monet de Lamarck, 18th century French naturalist.

It is very similar in appearance to A. laevis, with the exception that its young stems and leaves are sericeous (silky haired) whereas those of A. laevis are smooth. Otherwise both plants feature showy, 5-petaled, slightly fragrant, white flowers in drooping clusters that appear in early spring (April) before the leaves. Flowers give way to small, round, edible berries which ripen to dark purplish-black in June (hence the common name of Juneberry) and resemble blueberries in size, color and taste. Berries are often used in jams, jellies and pies. Finely-toothed, elliptic to oblong leaves emerge bronze-purple in spring, mature to dark green in summer and turn red-orange in fall.
