Title: New Taxa and New Combinations in the Genus Erysimum in North America
Abstract: This partial treatment of Erysimum is derived from an unpublished monograph of the genus and its approximately twenty-five species and eight varieties in North America, concerning which the writer has made extensive taxonomic study in various American herbaria and afield through most of the range of taxa in the United States.Citations of characteristic collections and extensive discussions of taxonomy, synonymy, ecology and geology are omitted for lack of space.The writer's complete and named collections including types are in the Dudley Herbarium at Stanford University and duplicates are deposited variously elsewhere.
