Camellia zijinica (Theaceae), a new species endemic to Danxia landscape from Guangdong Province, China
A new species of the genus Camellia (Theaceae), Camellia zijinica, discovered in the Danxia landscape from Guangdong Province, China, is characterized and illustrated. Phylogenetic analysis based on chloroplast genomes suggested its affinity with C. drupifera, C. oleifera and C. fluviatilis, however, it morphologically differs from all of the latter by leaf shape and size. Phonologically, it most closely resembles C. microphylla, but can be distinguished from the latter by its young branchlets glabrous (vs. densely pubescent), fewer bracteoles and sepals, diverse leaf shape, midvein raised slightly with sparsely pubescent or glabrous (vs. prominently with densely pubescent) and leaf adaxially matt (vs. vernicose) when dried. By morphological and molecular analyses, Camellia zijinica represented a distinct new species of C. sect. Paracamellia.
