Maryland goldenaster, Chrysopsis mariana

Maryland is the most wide ranging of the goldenasters in genus Chrysopsis. Most of the rest are restricted to Florida. Historically, there has been a lot of confusion with goldenasters. They've been placed in several genera, most often Heterotheca. Now, as John Semple says in Flora of North America, "The cytotaxonomy of Chrysopsis has been studied in detail with the karyotypes of nearly all the species illustrated, and allopolypoid origins of the C. gossypina complex documented, and the cytogeography of the four ploidy levels of C. mariana described." So now we know! Or we can just figure this is C. mariana since it wasn't in Florida. They all do look a lot alike. The Delaware tribe used this to treat several maladies, even after they were moved to Oklahoma, where it doesn't grow. Those newer plants were probably Heterotheca, and it was all placebo effects in any case. Maryland goldenaster grows in AL, DE, FL, GA, KY, LA, MD, MS, NC, NJ, NY, OH, PA(E), RI(T), SC, TN, TX, VA, and WV. Colquit Co GA, 10/19/15. Aster family, Asteraceae.
