title: No taxon left behind? – a critical taxonomic checklist of Carpinus and Ostrya (Coryloideae, Betulaceae)
abstract: Hornbeams (Carpinus) and hop-hornbeams (Ostrya) are trees or large shrubs from the northern hemisphere. Currently, 43 species of Carpinus (58 taxa including subdivisions) and 8 species of Ostrya (9 taxa including sudivisions) are recognized. These are based on 175 (plus 16 Latin basionyms of cultivars) and 21 legitimate basionyms, respectively. We present an updated checklist with publication details and type information for all accepted names and the vast majority of synonyms of Carpinus and Os
