Rhododendron luohanbaense (Ericaceae), a new species from northeast Yunnan, China
Rhododendron luohanbaense, a new species of Ericaceae, is described from Zhaotong City in northeastern Yunnan Province, China. Morphologically, it is most similar to both R. pachytrichum and R. maculiferum and can be classified into the subgen. Hymenanthes sect. Pontica subsect. Maculifera. However, it can be easily distinguished by markedly smaller and narrower leaves with acuminate apex, abaxial midribs densely covered with woolly indumentum, yellowish-green corollas speckled with green or purple dots, inflorescences bearing up to 7 flowers, flowers with ovary densely pilose, capsule densely brown setose. Phylogenomic evidence, based on a coalescent-based species tree reconstructed from 5358 single-copy nuclear orthologous genes, also supports recognition of the new taxon.
