Description

Amelanchier ovalis, commonly known as snowy mespilus (a name which is also attached to the related A. lamarckii) is a serviceberry shrub. Its pome fruits are edible and can be eaten raw or cooked. The species is native to central and southern Europe, as well as North Africa and the Middle East. "Amelanchier (/æməˈlænʃɪər/ am-ə-LAN-sheer), also known as shadbush, shadwood or shadblow, serviceberry or sarvisberry (or just sarvis), juneberry, saskatoon, sugarplum, wild-plum or chuckley pear,is a genus of about 20 species of deciduous-leaved shrubs and small trees in the rose family (Rosaceae). Amelanchier is native to temperate regions of the Northern Hemisphere, growing primarily in early successional habitats. It is most diverse taxonomically in North America, especially in the northeastern United States and adjacent southeastern Canada, and at least one species is native to every U.S. state except Hawaii and to every Canadian province and territory. Two species also occur in Asia, and one in Europe. The taxonomic classification of shadbushes has long perplexed botanists, horticulturalists, and others, as suggested by the range in number of species recognized in the genus, from 6 to 33, in two recent publications. A major source of complexity comes from the occurrence of hybridization, polyploidy, and apomixis (asexual seed production), making species difficult to characterize and identify. The various species of Amelanchier grow to 0.2–20 m tall; some are small trees, some are multistemmed, clump-forming shrubs, and yet others form extensive low shrubby patches (clones). The bark is gray or less often brown, and in tree species smooth or fissuring when older. The leaves are deciduous, cauline, alternate, simple, lanceolate to elliptic to orbiculate, 0.5–10 x 0.5–5.5 cm, thin to coriaceous, with surfaces above glabrous or densely tomentose at flowering, and glabrous or more or less hairy beneath at maturity. The inflorescences are terminal, with 1–20 flowers, erect or drooping, either in clusters of one to four flowers, or in racemes with 4–20 flowers. The flowers have five white (rarely somewhat pink, yellow, or streaked with red), linear to orbiculate petals, 2.6–25 mm long, with the petals in one species (A. nantucketensis) often andropetalous (bearing apical microsporangia adaxially). The flowers appear in early spring, ""when the shad run"" according to North-American tradition (leading to names such as ""shadbush"").
