Summary
A new species of Camellia sect. Piquetia (Theaceae), C. hiepii sp. nov. from the Chu Mu Mountains, M'Drak District, Daklak Province, Vietnam, is described and illustrated. The new species is most similar to C. longii Orel & Luu, but differs in having young branches sparsely pubescent, larger leaf blades, more secondary veins, flowers 8 ‒ 9 cm in diameter with more petals, longer stamens, and shorter styles. Photographs, an illustration, vernacular names, and a preliminary conservation assessment are provided.
