Sorbus oligodonta 少齿花楸

Sorbus oligodonta (kite-leaf rowan) is a species of rowan native to northern Yunnan, southeastern Tibet, and western Sichuan in China as well as to Myanmar.

It is a small to medium-sized deciduous tree growing to 5–15 m tall, with a rounded crown and dark grey bark, and slender shoots. The leaves are green to slightly glaucous-green above, paler beneath, 10–18 cm long, pinnate with 9-17 oval leaflets 3–4.5 cm long and 1–2 cm broad, broadest near the apex (hence the English name 'kite-leaf'), rounded at the end with a short acuminate apex, and very finely serrated margins; the basal leaflets are smaller than the apical leaflets. They change to a dark orange-red in late autumn, later than most other rowan species. The flowers are 8 mm diameter, with five yellowish-white petals and 20 yellowish-white stamens; they are produced in corymbs 6–12 cm diameter in late spring to early summer. The fruit is a pome 7–8 mm diameter, pale to deep pink with a persistent dark carpel, maturing in late autumn; the fruit stalks are distinctively red. The fruit commonly persist long into the winter after leaf fall; after being softened by frost they are readily eaten by thrushes and waxwings, which disperse the seeds.
