Camellia yangii is named after the leading collector of its type, Dr. Shixiong Yang, an expert of the family Theaceae at Kunming Institute of Botany, Chinese Academy of Sciences. The Chinese name of C. yangii is proposed as ” 三萼茶 ” because it bears three sepals in the flower.	en	Zhao, Dongwei (2025): Camellia yangii (Theaceae), a new species of tea plants (Camellia section Thea).
