Discussion

Some authors consider </i>subsp.<i> caroliniana to be a species complex composed of multiple morphotypes that hybridize along a wide zone in Florida; North American populations would have been derived from three independent migrations from the northern Bahamas (M. B. Cruzan 2005; S. D. Maskas and Cruzan 2000; K. McBreen and Cruzan 2004; Jiongqion Wang and Cruzan 1998). The morphotypes differ mainly in leaf shape and indument; leaf traits and plasticity responses toward narrower shape and higher trichome density are associated with increased drought conditions (J. J. Picotte et al. 2009).
