Sorbus oligodonta
Sorbus oligodonta, also known as the kite-leaf rowan and white-fruited rowan, is a species of rowan found from the eastern Himalaya to south-central China, northern Vietnam and Myanmar.
Description
Sorbus oligodonta is a small to medium-sized deciduous tree growing to 5–15 m tall, with a rounded crown and dark grey bark. The leaves are green to glaucous blue-green above, paler beneath, 10–26 cm long, pinnate with 9-17 oval leaflets 3–5.5 cm long and 1–2 cm broad, broadest near the middle or apex, 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 white or yellowish-white petals and 20 yellowish-white stamens; they are produced in corymbs 6–15 cm diameter in late spring to early summer. The fruit is a pome 7–8 mm diameter, white or pale to deep pink with a persistent dark or pinkish 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.It is a tetraploid species which breeds true without pollination by apomixis.
