|discussion=<p><i>Rhynchospora caduca</i> has its closest relationships with the even more robust <i>R. odorata</i> Grisebach, on the one hand, and the swampinhabiting, more slender, and rhizomatous <i>R. mixta</i> Britton ex Small, on the other. Intergrades with <i>R. odorata</i> appear in Alabama and northwest Florida; intergrades with <i>R. mixta</i> appear where ranges overlap in both the Atlantic and Gulf coastal plains.</p>
