Poets and botanists do go on. "A rose by any other name". "A rose is a rose". . . is a polymorphic allotetraploid derived from diploids, with two nothospecies representing secondary hybridization and retrogression. Shakespeare and Stein at one end of a spectrum, Lewis, Ertter and Bruneau at the other in Flora of North America. The latter mention past treatments of our natives, that run from 15 to 129 species. Pasture rose seems to be a relatively steady member of the group, different in its low stature and other details of leaf and thorn. Certainly beautiful by any name. Pasture rose grows in AL, AR, CT, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, NC, NE, NH, NJ, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV, NB, NS, ON, PE, QC, and on SPM.
