Magnolia officinalis var. biloba

Magnolia officinalis (commonly called houpu magnolia or magnolia bark) is a species of Magnolia native to the mountains and valleys of China at elevations of 300–1500 m. It is a deciduous tree up to 20 m tall with broad, fragrant white flowers and two varieties distinguished by leaf shape, differing slightly from Magnolia obovata primarily in fruit base shape. Its aromatic bark, traditionally used in Chinese medicine as "hou po," is now primarily sourced from cultivated plants.
