Osmanthus

Osmanthus /ɒzˈmænθəs/ is a genus of about 30 species of flowering plants in the family Oleaceae. Most of the species are native to eastern Asia (China, Japan, Korea, Southeast Asia, the Himalayas, etc.) with a few species from the Caucasus, New Caledonia, and Sumatra. Osmanthus has been known in China since ancient times with the earliest writings coming from the Warring States period; the book Shanhai Jing: Nanshan Jing (Classic of Mountains and Seas: Classic of the Southern Mountains) states: "The first peak of the Que Mountain range is Mount Zhaoyao, rising by the western sea, where many osmanthus trees grow, and where rich veins of metals and jade lie hidden."
