Nomenclatural notes on some European elm names (Ulmaceae)

The typification of the elm names Ulmus laevis, U. minor, and U. pumila is discussed. Ulmus laevis is lectotypified on a Pallas illustration published in his Flora Rossica. No original material could be located for U. minor and a neotype is designated (a specimen at SLBI). Ulmus pumila is lectotypified on a specimen in LINN. While the lectotype lacks samaras, an epitype is not designated because it is unclear whether there are any species with similar vegetative morphology in the area where the type was collected.
