Camellia japonica L.
Camellia, the camellias, is a genus of flowering plants in the family Theaceae. They are found in eastern and southern Asia, from the Himalayas east to Japan and Indonesia. There are 100–250 described species, with some controversy over the exact number. The genus was named by Linnaeus after the Jesuit botanist Georg Joseph Kamel, who worked in the Philippines, though he never described a camellia. This genus is famous throughout East Asia; camellias are known as cháhuā (茶花) in Chinese, "tea flower", an apt designation, as tsubaki (椿) in Japanese, as dongbaek-kkot (동백꽃) in Korean and as hoa trà or hoa chè in Vietnamese.
The most famous member – though often not recognized as a camellia – is certainly the tea plant (C. sinensis). Among the ornamental species, Camellia japonica and C. sasanqua are perhaps the most widely known, though most camellias grown for their flowers are cultivars or hybrids.
