Taxonomic position.

Family Rosaceae Juss., genus Pyrus L.

Morphology and biology.

Tree, up to 8-10 m tall, sometimes a shrub with a broad crown and numerous prickles. Young shoots are densely tomentose, reddish green. Leaves are narrow, lanceolate or oblong-ovate, 6-9 cm long and 0.5-2 cm wide, with dense pubescence below and sometimes above. Leaf edges are smooth or sparsely crenate, with dark glandules on the dent tips. Flowers, 2.5-3 cm in diameter, are assembled into inflorescences, each consisting of 5-7 (9) flowers. Petals are white, narrow, concave. Fruits are roundish or obtusely conical, yellowish green, sometimes with rusty spots; slightly pubescent young fruits later become bare. Pulp is coarse, sour-sweet, very astringent, hardly edible. Entomophilous. Zoochore. Blossoms in April/May; bears fruit in late July/September. 2n=34.


Occurs in the Caucasus (Eastern Ante-Caucasus, Daghestan, Eastern and Southern Transcaucasia, Talysh), Western Iran, and Asia Minor.


Xerophyte. Occurs in the lower and middle mountain zones from 300 to 1,800 m above sea level in arid, sparse growths of trees, on dry stony slopes and in steppes.

Utilization and economic value.

Food (fruit), melliferous. Has great importance as a drought- and frost-resistant species and is undemanding to soils, thus being promising for breeding as well as for utilization as a seedling stock.
