Pyrus betulifolia (Birch-leaved Pear)

Pyrus betulifolia, often known as the Birchleaf Pear or Tang li in Chinese, is a deciduous wild pear tree endemic to the leafy woods of northern and central China, as well as Tibet. In ideal conditions, it may reach a height of 10 metres. Its leaves are protected against predators by ferocious thorns. It gets its scientific name betulifolia, which means "birch leaf," from its slender and elongated leaves, which resemble tiny birch leaves. Its tiny fruit are utilised as components in rice wine and sake in China and Japan, respectively. It's a rootstock that's utilised to transplant popular Asian pear cultivars.
