Abstract


Rhododendron baihuaense sp. nov. is described as a new species endemic to Yunnan, China, that has, to date, only been found in Baihualing on the eastern side of the Gaoligong Mountains. Morphologically, R. baihuaense can be readily distinguished from R. hanceanum and R. genestierianum, by its absent scales on mature leaves, only 2–5 flowers per inflorescence, the funnel-shaped flower and white corolla, and its slender and erect style. A molecular analysis based on the four standard DNA barcodes (rbcL, matK, trnH-psbA and ITS) indicates that R. baihuaense is genetically distinct from R. hanceanum and R. genestierianum, and, together with the morphological differences, is described here as a new species.
