Other

Notes: Sandy or rocky limestone soils. Mostly May–Oct. Turner et al. (2003) cited Bell, Bexar, Caldwell, Guadalupe, Hays, and Travis cos. on the w margin of East TX and Brazos Co. (cultivated?) further e (they did not recognize varieties); w part of East TX s and w throughout the w 2/3 of TX; w U.S. from CA e to OK and TX, also FL and SC. This species has an interesting amphitropical distribution, being found in both North America and s South America (Allred 1981). While some authorities (e.g., Kartesz 1999; Allred 2003g) do not recognize varieties, we are following Hatch (2002) in recognizing the variation at the varietal level based on the usually distinct morphology.
