W Guizhou, SW Sichuan, Yunnan.This species is cultivated or semicultivated in W Yunnan as a seed oil crop. Selected forms, particularly with large, double or semidouble flowers, have been propagated for hundreds of years as garden plants in Dali, Kunming, Lijiang, Tengchong, and adjacent areas. Some extant cultivars date back to at least the Ming Dynasty (1368-1644 C.E.)."Camellia brachygyna" as given in FRPS (49(3): 74. 1998) was a typographical error for C. brevigyna included in synonymy here.【引自:Flora of China】
