Taraxacum altune D. T. Zhai & Z. X. An is reduced to synonymy of Crepis minuta Kitamura. The recently described Taraxacum altune (Zhai & An, 1995) was based on a flowering specimen collected by Y. H. Wu in 1988. During the revision of Taraxacum for Flora Reipublicae Popularis Sinicae, we examined additional specimens of the same species, including fruiting material. The achenes of this material are blackish, cylindric, narrowed toward the apex, beakless, smooth, and ribbed, and the scapes have a small leaf. In Taraxacum the leaves are all basal, and the achenes are fusiform to oblanceolate, often spinulose near the apex, usually slender-beaked, and clearly with a more or less swollen region between the beak and body. Therefore, plants of TI altune represent a species of Crepis L. Critical comparison of the type material of TI altune with Chinese species of Crepis (Tang, 1985) reveals that TI altune is conspecific with Crepis minuta Kitamura. The type of C. minuta was collected by Kawaguchi (SM 96895, now TNS) from Xizang (Tibet). Crepis minuta Kitamura, Acta Phytotax. Geobot. XV: 70. 1953. Taraxacum altune D. T. Zhai & Z. X. An, J.
