This species is known from Kwangtung Province, Hainan, and 
Tonkin, and is represented by Levine 1989 from Teng Woo 
Mountain, Kwangtung Province, and by Hongkong Botanic Gar- 
den 22U3 from Hainan. The oldest valid specific name is here 
adopted, as Loureiro’s description applies in all respects to the 
species as currently interpreted.
