Phalaenopsis lobbii (Rchb. f.) H. R. Sweet, a newly recorded species of Orchidaceae from China, is described. This species resembles Phalaenopsis gibbosa and Phalaenopsis parishii, but differs by having white flowers, not zigzag rachis and an irregular-subdenticulate callus between the two side-lobes of the lip.
