Abstract
A new species of Orchidaceae, Phalaenopsis yarlungzangboensis from Motuo, Xizang, is described and illustrated based on morphological characters and molecular phylogenetics. Phalaenopsis yarlungzangboensis is distinguished from its relatives by its column foot with triangular wings, subrectangular lateral lobes concave, lower part white with a deep purplish red spot and hairy and upper part pale yellow with densely rusty spots, rhombic middle lobe with a fleshy horned appendage at base, disc grooved. Molecular phylogenetic analyses and morphological characters indicated that P. yarlungzangboensis is closed to P. deliciosa, P. gibbosa and P. lobbii.
