Hey Justin and everone - I have seen this *Oxalis* species identified in a variety of southern plant guides over the years under several names but there seems to be some agreement these days that it is *Oxalis debilis.** *I learned this plant as*O. rubra *as well. It is from South America as well*, *though it is widely naturalized from the coastal Carolinas throughout the Gulf Coast and into Texas. Of the three non-native pink flowered* Oxalis *that can be commonly found naturalized in the southeastern U.S., it the most commonly encountered. Of the three non-native pink flowered* Oxalis* and the native*O. violacaea, O. debilis ** *is the only one I am aware of that has the dark veining in the throat of the flowers and heart-shaped segments of the leaf and that are mostly glabrous*.** *There are pictures and some information at this link, though note that one of the pictures labeled* O.violacaea* is a slightly over exposued photo of*O. debilis. *http://florida.plantatlas.usf.edu/Results.aspx Alani Davis Tallahassee, Fl* *
