Abstract
This study describes Camellia nganiana Nguyen-Phi & Luu as a new red-flowered species of section Piquetia from Lam Dong Province, Vietnam. Morphologically, it closely resembles C. phuongchiana but differs by its entire leaf margins, shorter petiole, larger bracteoles, 6–9 petals, larger petals, shorter and glabrous filaments. The new species is fully described and illustrated based on living collections and compared with closely related taxa. As a result, Camellia sect. Piquetia is currently recognized to comprise eighteen species, including nine with red to purple flowers.
