Discussion
Variety citrullifolium is found in central and western Texas south to Mexico. The plants from central Texas differ from those of western Texas and Mexico in having more rounded ultimate leaf lobes, leaf undersides often lacking stellate hairs, and longer fruiting inflorescences. In Florida, var. citrullifolium has escaped from cultivation and become naturalized. Massachusetts records (F. C. Seymour 1982) are historical (1885, 1913, 1949) as introductions that did not persist.
Selected References
None.
