bio.wikisort.org - PlantPyrus regelii is a species of wild pear in the family Rosaceae, native to Central Asia (except Uzbekistan, where it occurs but is considered introduced).[1] A small tree usually 6 m (20 ft) tall, but reaching 9 m (30 ft), its young branches are cloaked in a grey down, which provides visual interest when it is planted as an ornamental.[2] Its leaves, which are also downy when young, are exceptionally variable in shape, sometimes even on the same individual.[2] The fruit are small but typical pears, and are collected and eaten by local peoples.[3] The most xerophytic member of its genus, it is occasionally used as a rootstock for cultivated pear trees, as a garden ornamental, and for reforestation projects, all in dry areas.[2][4]
