binomial_authority =The Shipova ("× Sorbopyrus auricularis"), also known as the Bollwyller Pear, 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.

The hybrid first arose at Bollwyller 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 cultivars 'Bulbiformis' and 'Malifolia'. However shipova trees are not widely cultivated.
