Based on a fossil fruit from the early Miocene strata of the Most Basin in Northern Bohemia (Czech Republic), a new species of the genus Halesia L. of the family Styracaceae is described as Halesia mosbruggeri Kvacek, sp. nov. The fossil occurrence of this genus, which today shows a disjunct distribution, adds a further evidence for the ancient connection between North America and Eurasia during the Neogene.
