 In 2002, Henderson re-classified both of Small's species "Iris giganticaerulea" (located in coastal Alabama to Louisiana) and Iris savannarum (located in Alabama, Georgia, and Florida) as distinct species.Iris hexagona then was left to populations in South Carolina and a few regions in northern Florida.This was agreed and expanded on by Daniel Ward in 2011 (from the University of Florida), who linked "Iris kimballiae" as a variant of "Iris savannarum".
