Аннотация:The original material of Sorbus danubialis (Jáv.) Prodan, and the most similar taxa described from Hungary ( S. javorkae (Soó) Kárpáti, S. sooi (Soó) Kárpáti & Soó and S. pseudodanubialis Kárpáti), have been examined along with other specimens cited either as referable to those taxa or to S. cretica (Lindl.) Fritsch in the monograph of Sorbus in Hungary and adjacent countries by Kárpáti. Lectotypes are designated for S. javorkae and S. sooi ; these two names and S. pseudodanubialis are reduced to synonymy of S. danubialis because of insignificant differences in morphology. Diagnostic characters and the distribution of S. danubialis are discussed based on a new description and a map of the distribution in Hungary. The authorship of S. danubialis is discussed. The principal infraspecific taxa in the “Flora Hungarica” of Jávorka (1924–1925) are interpreted as validly published at the rank of subspecies under ICN Art. 37.5.
