This small tree is widely distributed across the southern Iberian Peninsula and northern Morocco, where it coexists with four Pyrus species: P. communis L., P. cordata Dew., P. spinosa Forssk, and P. nivalis Jacq. Characteristics to discriminate these species are the width of fruit peduncle, petal size, leaf width and petiole length served to the taxa.
