"This attractive species is evidently allied to P goetzeana which it closely resembles in general appearance. It differs from this species and others of the section in the markedly rugulose lobes of the lip and the apparent abscence from this organ of the clavate hairs so characteristic of the other species. The small basal pseudobulbs, the long narrow leaves and the comparitively thin-textured flowers P. rugosilabia agress with the others of the section." Summerhayes 1947-8." Summerhayes 1947/8
