The Shipova (× Sorbopyrus auricularis) is a hybrid between the European Pear (Pyrus communis) and the Common Whitebeam (Sorbus aria). It is a small to medium-sized tree growing to 10-18 m tall, with deciduous oval leaves 7-11 cm long and 5-6 cm broad. The fruit is a pome 2.5-3 cm long; it is edible with a sweet, yellowish flesh, which tastes similar to a Nashi Pear.
History[edit source | edit]
The hybrid, known as the Bollwiller Pear, first arose at Bollwiller in Alsace, France, before 1619, and has mostly been propagated by grafting since then; it is nearly sterile, only rarely producing any viable seeds. Two successful seedling propagations have been named as the cultivar 'Bulbiformis' and as the species Pyrus malifolia. However shipova trees are not widely cultivated. Shipova is the only known species in the nothogenus × Sorbopyrus (the hybrid genus of Sorbus and Pyrus)
