Pyrus elaeagrifolia, the oleaster-leafed pear, is a species of wild pear plant in the genus Pyrus (Rosaceae), the specific name referring to the similarity of its foliage to that of Elaeagnus angustifolia - the so-called 'wild olive' or oleaster.

It is native to Albania, Bulgaria, Greece, Romania, Turkey, and Ukraine's Crimea.[1] It prefers dry habitat and elevations up to 1,700 meters (5,600 ft). It grows to a height of 10 meters (33 ft). The flowers are hermaphrodite.[2] The species is highly resistant to drought and frost. It is sympatric with Pyrus pyraster. The species was first described by Peter Simon Pallas in 1793.[3]

Varieties

Known subspecies are: Pyrus elaeagrifolia subsp. elaeagrifolia (no accessions), Pyrus elaeagrifolia subsp. kotschyana, Pyrus elaeagrifolia subsp. bulgarica, and Pyrus elaeagrifolia subsp. yaltirikii.[1][4]
