Betula chinensis

Betula chinensis, commonly known as dwarf small-leaf birch,[1] is a species of birch that can be found in China and Korea on the elevation of 700–3,000 metres (2,300–9,800 ft).

[2] The species is 5 metres (16 ft) tall with either yellow or yellowish-brown colour.

Flowers bloom from May to June while the fruits ripe from July to August.

It appears to be a triple hybrid between B. calcicola, B. potaninii and B. chichibuensis.
