The genus Rosa L. (Rosaceae) was recently treated floristically for North America, but range extensions and an additional taxon have been confirmed since then and are detailed here. These new reports document range extensions in the US and Canada of some native and introduced Rosa species, and new distributions and population data for several established Rosa hybrids (nothospecies). Some introduced European species and some nothospecies are more widespread than previously realized, and some are actively spreading.
