A list of endemic species of vascular plants can be generated at (bonap.net/tdc). Among the areas especially important for endemic plants in Canada is the Athabasca Sand Dunes (Encyclopedia of Saskatchewan). A list of threatened Canadian endemic species appears in "Our Home and Native Land" (p. 42 of BHCG pdf file).
