|discussion=<p><i>Oxalis macrantha</i> is restricted mostly to limestone glades in Alabama, Kentucky, and Tennessee. It is recognized by its villous to villous-hirsute stems, flowers in umbelliform cymes, and large yellow to yellow-orange corollas with red lines proximally. The lines in the throat remain visible after drying and usually can be seen on herbarium specimens even from the outside of the flower. A similar pattern also occurs in other species, especially <i>O. grandis</i>, <i>O. illinoensis</i>, and <i>O. texana</i>.</p><!--
--><p>Seemingly disjunct plants of native habitats in Nuevo León, Mexico, identified as <i>Oxalis macrantha</i> apparently are more common than reported by G. L. Nesom (2009b). Whether these are actually disjunct or a parallel morphological expression derived from some Mexican species needs to be investigated.</p>
