Flower: pale yellow to yellow, very small, 1.3-2 cm in diameter with 5-9 petals. Filament in tube with pollen on the mouth of the tube. Leaf: ca. 10 cm long, ca. 4 cm wide, leathery and glossy. Probably the most hairy species in the genus Camellia. The upper surface has short hairs on the main veins, while the lower surface has long white hairs on the main veins and on the entire leaf surface. Petiole is 3 m long and is surrounded by long hairs.Blooming season: September to March next year. Distribution: North-east Mountain in Vietnam.
The plant was discovered by S. Kirino, N. Hakoda and Tran Ninh in 1998 in Van Lang district, Lang Son province. In 1999, the author Tran Ninh published in the Journal Genetics & Applications with the scientific name Camellia kirinoi. The Vietnamese name is Kirino Tea, named after the Japanese scientist S. Kirino who had made many contributions to the research of Vietnam's indigenous camellias.
This species is very similar to Camellia luteocalpandria (2021) in the same Section Calpandria in yellow flower, but differs on Petals outer side pubescent (C. kirinoi) vs. Petals both sides glabrous (C. luteocalpandria).
