A new species of Rhododendron (Ericaceae) from northeastern Yunnan, China

The genus Rhododendron Linnaeus (1753: 392) has more than 1,000 species that have been recognized in the temperate areas of the world (Chamberlain et al . 1996). In China, ca. 600 species of Rhododendron have been confirmed, including numerous species described after the publishing of Flora of China (Chen et al . 2010, Chen et al . 2012, Ma et al . 2013, Liao et al . 2015, Ma et al . 2015, Cai et al . 2016). They occur in most of China’s provinces except Xinjiang and Ningxia (Ma et al . 2014). Among these provinces, Yunnan, Sichuan and Tibet have the greatest diversity.
