Revision of genus Digitaria in BP Herbarium Carpato-Pannonicum collection helped to discover the historical occurrence of Digitaria ciliaris (Retz.) Koeler from Győr, in the area of an old cotton and wool processing and textile factory. However, it has been proved that the previously publis­hed Hungarian records of the species are all wrong, as the Digitaria-keys of Hungarian herbals misin­terpreted the taxon, mainly as a synonym of D. sanguinalis subsp. pectiniformis. The herbarium survey confirmed that D. sanguinalis is the most common taxon in Hungary. D. sanguinalis subsp. pectiniformis is also widespread, but probably somewhat under-mapped. Probably not native to Hungary, most pro­bably an archeophyte taxon. Specimens have been collected from disturbed habitats associated to railways and from xerothermic vineyard areas for over a hundred years. D. ischaemum is certainly native to the region, with a recognisable natural distribution pattern, and is found mainly in the sandy and gravelly soils of the lowland and hilly areas of the country. This species has recently become more common in urban areas across the country with the recent spread of sand-lined pavements. D. ciliaris of tropical/subtropical origin is a casual alien species that was formerly present in the Hungarian flora.
