Discussion | Spring-flowering plants with most of their proximal leaves pinnately lobed or coarsely toothed, mainly found in south-central Texas, have been treated as var. australis (B. L. Turner and M. Whalen 1975). Plants from near or on beaches of the Atlantic and the Gulf of Mexico, usually with somewhat fleshy leaves and often persisting for more than one year, have been distinguished as var. picta. Cultivars of Gaillardia pulchella (or of hybrids between G. pulchella and G. aristata) are used horticulturally. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
