Camellia pukhangensis (Theaceae), a new species with yellow flowers from Quy Hop District, Nghe An Province, Vietnam, is described and illustrated. Camellia pukhangensis has nearly sessile leaves with an attenuate to caudate apex, cordate base, hirsute abaxial surface, hirsute adaxial midrib, hirsute petiole, deltate to ovate perules hairy on the outer surface, bright yellow orbicular to obovate petals hairy on the outer surface, androecium pubescent to two-thirds from the base, pubescent ovoid ovary with three (or four) locules and three (or four) pubescent styles free to the base. The morphological data support the provisional placement of C. pukhangensis in Camellia sect. Archecamellia Sealy.

성능/효과
Notes: Camellia pukhangensis is characterized by leaves abaxially hirsute and adaxially hirsute only along the midrib (section Eriandra Coh. St.); solitary flowers at the apex of branches, short pedicels, perules more than 10 (section Archecamellia Sealy); the gynoecium is 3(or 4) locular with three free styles (section Chrysantha Chang). However, species in section Eriandra are characterized by small leaves hairy only on the midrib, small white flowers, the androecium in 2 or 3 whorls and compound styles (Chang and Bartholomew, 1984; Ming and Bartholomew, 2007).
The new species, C. pukhangensis, has many characteristics of section Archecamellia, such as solitary flowers at the end of branches,11–13 indistinguishable persistent perules, pubescent stamens connate into a cup, a pubescent gynoecium with 3(or 4) loculi and 3(or 4) free styles.
