OKSANA / CITRINA PLANTS

Oksana is known as Hong Kong Kumquat. This species grows wild in Hong Kong and in the Chekiang and Kwangtung provinces of China. This Kumquat is apparently of ancient origin, for it is rather widely distributed in the wild and is undoubtedly the chin chu (golden bean) or shan chin kan (mountain golden mandarin) described by Han Yen-chih in 1178.
