Pyrus syriaca, commonly known as the Syrian pear, is a deciduous tree in the family Rosaceae.
The tree grows up to 13 metres tall with a broad, sometimes irregular . It features reddish-brown to grey branches marked by small , elliptic to ovate leaves with toothed margins, and white five-petalled flowers that appear in loose clusters during late April to early May. Its fruits are greenish-yellow pomes ranging from nearly spherical to broadly pear-shaped, maturing from late August through October.
Native to the eastern Mediterranean region and adjacent areas, its range extends from southern Turkey and the Transcaucasus through Cyprus, western Syria, northeastern Iraq, Lebanon, western Jordan, and into southwestern Iran. The species favours dry, well-drained habitats, often growing on sun-exposed, rocky slopes and in open oak forests, sometimes forming nearly pure stands alongside almond, maple, and hawthorn trees.
Pyrus syriaca is a deciduous tree reaching up to tall, with a broad, sometimes irregular crown. The branches are reddishâÂÂbrown to grey and marked by small, lensâÂÂshaped openings called lenticels. Buds are broadly oval (3âÂÂ7 mm long), initially covered in soft hairs that soon wear away, while young shoots bear a silky, dense () that becomes (hairless) with age. Leaves vary from longâÂÂelliptic to or , seldom , measuring 1âÂÂ10 by 0.8âÂÂ4 cm; the broadest part typically lies at or just below the middle. Leaf margins are toothed ( to ), each tooth ending in a small, deciduous . The upper surface is glossy and hairless; the lower surface carries sparse, short hairs that tend to disappear as the leaf matures.
Flowering occurs in late April to early May, with blossoms borne in loose clusters (corymb) of 7âÂÂ20 flowers. Individual flowers span 1.5âÂÂ3 cm across, each with five white, orbicular to petals (8âÂÂ14 by 6âÂÂ12 mm) anchored by a short stalk (claw) to a cupâÂÂshaped hypanthium densely clothed in hairs. are triangular to linear (4âÂÂ7 mm long), acute at the tip, and tomentose on both surfaces. Typically five styles up to 8 mm long and 20âÂÂ35 stamens arranged in one or two concentric rings fill the flower cup.
Mature fruits are pomes that range from nearly spherical to broadly pearâÂÂshaped (1.5âÂÂ3.5 by 1.5âÂÂ3.5 cm), greenishâÂÂyellow when ripe. The persistent sepals remain to the fruit surface. Each pome is borne on a thickened stalk () that often widens below the fruit, giving it extra support. Fruit matures from late August through October.
Pyrus syriaca occupies dry, wellâÂÂdrained habitats across the eastern Mediterranean and adjacent regions. Its range extends from southern Turkey and the southern Transcaucasus through Cyprus, western Syria, northeastern Iraq, Lebanon and western Jordan, reaching into southwestern Iran.
Within IranâÂÂwhere it is the most widespread pear speciesâÂÂit grows on dry slopes in open forests of the Zagros Mountains. There, it grows alongside other species of pear and oaks. In the Arasbaran area of northeastern Iran, it occurs in denser woodland with other pears, oaks, hornbeam and elm.
