A new species of Camellia L. (Theaceae), C. maiana Orel, endemic to the Da Lat Plateau in southern Vietnam, is described and illustrated. The newly described species has variable-sized, ovate to obovate leaves; 2-whorled, terminal, sessile flowers exhibiting emarginate, opaque to translucently white, finely textured petals; a compound style consisting of four parts that are fused at the base; persistent bracteoles; and a superior 4-chambered ovary. The morphological evidence supports taxonomic placement as a transitional member of Camellia sect. Stereocarpus (Pierre) Sealy.
