Abstract: A new triploid Sorbus species, S. pelsoensis is described in Sorbus subgenus Tormaria (Sorbus latifolia group) from Balaton Uplands (Hungary). Illustrations (photographs of the type specimen, leaves, and fruits) and a detailed distribution map are provided as well as photographs of in situ flowering and fruiting individuals. S. pelsoensis is a stenoendemic species putatively derived from hybridisation between S. torminalis and S. graeca. The species is restricted to two neighbouring valleys with about 100 individuals found in thermophilous oak woodlands (Vicio sparsiflorae-Quercetum pubescentis), pubescent oak shrub woodlands (Cotino-Quercetum pubescentis), mixed forests of rocky slopes (Primulo veris-Tilietum platyphyllae), mixed karstic forests (Fago-Ornetum), and at the light-rich margins of these plant communities, respectively.
