Bulbophyllum yingjiangense, a new species from Yunnan, China: morphological and molecular evidence (Orchidaceae; Epidendroideae)

Bulbophyllum yingjiangense (Epidendroideae; Malaxideae), a new species from western Yunnan, China, is illustrated and described here based on morphological and phylogenetic evidence. The new species is phylogenetically close to B. rothschildianum, and they are also similar in floral morphology. The new species differs in its yellowish green flowers without stripes, pseudobulbs with obvious ridges, lateral sepals glabrous with short tails and leaf with white waxy powder on its adaxial surface.
