(pears; family Rosaceae)
A genus of deciduous, sometimes thorny trees and shrubs, that have simple leaves and flowers borne in umbel-like clusters. There are 5 sepals, 5 petals, 20–30 purple stamens, and 2–5 carpels fused together and with the receptacle, though the styles are separate. The flesh of the pear-shaped fruits contains numerous woody, grit-like cells, unlike that of apples (Malus). Many cultivars are grown for their fruits. There are about 20 species, occurring in northern temperate Eurasia.
