Notes: FNA3: "In many floras the names Consolida ambigua (Linnaeus) Ball & Heywood and Delphinium ambiguum Linnaeus have been misapplied to this taxon.
Consolida ajacis has escaped and become more or less naturalized in many temperate and subtropical parts of the world. It is by far the most commonly encountered species of Consolida in North America."
