DESCRIPTION Tree or shrubs up to 10 m tall. Rarely thorny, thorns up to 90mm long, with short twigs. Young shoots glabrous to villose. Buds 1.4-3.7 mm long × 2.1-3 mm in diameter. Leaves long villose, dull or bright green, cuneate or attenuate at base, lobes acute, finely serrate at margin. Middle leaves of flowering shoots 18-35 (-50) × 16-30 (-45) mm, lobes 1-2(-3) pairs, basal sinuses at lower half of lamina and extending nearly midvein, basal pair 2-3 (-4) times as long as wide, each lobe with (2-) 5-10 (-15) teeth in the upper 1/3 to 1/4; petiole (3-) 6-10 (-21) mm; stipules 4-7 (-15) × 1.5-4 mm, entire or irregularly (1-) 5-10 (-20) serrate glandular or eglandular teeth. Middle leaves of short shoots 20-40 (-55) × (15-) 20-40 (-50) mm, lobes 1-3 pairs, basal sinuses at lower half, sinuses extends to midvein, basal pair 1-2 times as long as wide, each lobe with 3-10 (-15) teeth in the upper 1/3-1/4; petiole (5-) 15-25 (-35) mm, stipules 1-2 × 0.3-0.6 mm, glandular serrate. Middle leaves of long shoots 25-40 (-60) × 25-40 (-65) mm, lobes 2-3 (-4) pairs, basal sinuses at lower half of the lamina, extending to nearly midvein, 2-2.5 times as long as wide, 6-12 (-20) teeth at upper 1/3-1/4; petiole 10-20 mm; stipules 5-10 (-25) × 2-4 (-15) mm with 8-20 (-45) glandular or eglandular irregular teeth. Inflorescence 20-40 × 30-50 mm, lax corymbose with 8-15 (-20) flowers, villose, densely villose; pedicel (2-) 4-7 (-10) mm, bracts 1.8-3 (-10) × 0.2-0.9 mm, deciduous, linear, entire or with (1-) 4-12 glandular teeth. Flowers 10-16 mm in diameter; hypanthium 3-5 × 3-5 mm; sepals (1.4-) 2-3 (-5.5) × 1.5-2 mm, triangular to linear, margin entire or glandular, acute or acuminate at apex; petals (4-) 5-6 (-9) × 5-6 (-7) mm; stamens 18 (-20), anthers pink; styles (1-) 2-3 (-4), hairy at base. Fruit (7-) 9-12 mm long × (6-) 7-10 (-15) mm ± globose to short oblong ± angular at base, dark shiny red, mostly hairy, flesh orange, juicy, sepals recurved on fruit; pyrenes (1-) 2-3 (-4), (5-) 7-9 × 4-6 mm, slightly sulcate dorsally and laterally. REMARK The description of the species was based on the collections of Browicz and Zielinski (deposited at KOR herbarium in Poland) and Y&amp;imath;ld&amp;imath;r&amp;imath;ml&amp;imath; (G and HUB herbaria). Both of the paratypes have been examined by the present author. Christensen &amp; Zielinski (2008) mentioned new material from Tav&amp;scedil;anl&amp;imath;, Kütahya which appeared to be an unusual location for this species. The present author therefore undertook extensive field research throughout Turkey and in many localities in Iran, which resulted in the reduction above of this species hybrid to synonymy with <i>C. meyeri</i> Pojark.
