"Appendicula lucbanensis" (Ames) Ames (Orchidaceae), an epiphytic orchid previously known only from the Philippines, is newly recorded in southern Taiwan. "A. lucbanensis" is easily distinguished from other known "Appendicula" species in Taiwan by having frequently branched stems, 2-4 cm long inflorescences, loosely arranged flowers, and flowers with ca. 4 mm long mentum.
