Magnolia officinalis subsp. biloba, a traditional Chinese medicinal plant, experienced severe declines in the number of populations and the number of individuals in the late 20th century due to the widespread harvest of the subspecies. A large-scale cultivation program was initiated and cultivated populations rapidly recovered the loss in individual plant numbers, but wild populations remained small as a consequence of cutting.
Magnolia officinalis (commonly called Houpu Magnolia or Magnolia-bark) is a species of Magnolia native to the mountains and valleys of China at altitudes of 300-1500 m. It is a deciduous tree growing to 20m in height. The bark is thick and brown but does not fissure. The leaves are broad, ovate, 20-40 cm long and 11-20 cm broad. The flowers are fragrant, 10-15 cm wide, with 9-12 (rarely to 17) white tepals, and appear from May to June.
