The southern border of the Great Basin Province is marked by the replacement of sagebrush by Larrea and Ambrosia (creosote bush and ragweed) … floras of arid regions [within the Madrean Subkingdom] are excluded and treated with either the Boreal Subkingdom (Great Basin Province) or with the Neotropical Kingdom (Mexican Xerophylic [Sonoran] Region)."
