The widest-ranging of all New World Xyrids and the most ample ecologically, Xyris jupicai is a frequent invader of disturbed or fallow open wetlands within its extensive range. In the southeastern United States it frequently shares habitat with two other species of its complex, namely X. difformis var. difformis and X. laxifolia. It differs from both in its lack of red pigmentation, from X. difformis by its more erect leaves and narrower, less prominently ribbed scapes, and from X. laxifolia by its narrower leaves and scapes, shorter, narrower, paler spikes, and translucent (rather than mealy), shorter seeds. Nonetheless, some difficult "calls" arise since all three flower at the same time and occasional chance hybrids do form.
