NOMENCLATURE AND TYPIFICATION OF LEPTARRHENA (SAXIFRAGACEAE)

Summary The correct name for the species in a monotypic Leptarrhena (Saxifragaceae) is L. pyrolifolia (D. Don) R. Br. ex Seringe. Reasons are outlined for believing that Rafinesque was the first to lectotypify the genus (with L. pyrolifolia ) and for believing that Small's choice of L. amplexifolia should be superseded. Both species names are lectotypified here, however. In a conspectus of the genus, nine synonyms are identified and one species name excluded.
