Sorbus thibetica

Sorbus thibetica (Tibetan whitebeam) is a species of flowering plant in the family Rosaceae, native to south western China and the Himalayas. Growing to 20 m (66 ft) tall by 15 m (49 ft) broad, it is a substantial deciduous tree. Like other whitebeams, the undersides of the leaves are white, giving a dramatic effect when the wind blows through them.
