Commonly cultivated for its edible fruit, this taxon is usually cited as Myrica rubra (Loureiro) Siebold & Zuccarini. However, in their publication of 1846, Siebold & Zuccarini provided a description only, with no reference, direct or indirect, to Morella rubra Loureiro (1790). Therefore, the name Myrica rubra Siebold & Zuccarini must be treated as new, preventing the combination in Myrica of Loureiro’s earlier name.

Forests in mountain slopes, valleys; 100-1500 m. Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hunan, Jiangsu, Jiangxi, Sichuan, Taiwan, Yunnan, Zhejiang [Japan, Korea, Philippines].
