A new species of Tropidia Lindl. (Orchidaceae), T. angustifolia C. L. Yeh et C. S. Leou, from Mt. Lilung, southern Taiwan is described and illustrated. The main difference between this species and another similar species, T. nipponica, is that T. angustifolia is characterized by its linear-lanceolate leaves with acuminate apex and acute base, and bigger sub-saccate lips. We also provide a new key to the species of Tropidia in Taiwan.
