● Henan (Jigong Shan).

One of the largest plantations of Yulania for growing medicinal xinyi is found at Jigong Shan Forest Station in Xinying, Henan. This plant may be one of the many hybrids that originate in plantations with different Yulania species, probably with Yulania biondii as one of the parents.
