|discussion=<p>The shady habitat of Lythrum curtissii, a rare, delicate-flowered species, is unlike that of other native species of Lythrum, which tend toward more open, sunny areas. Putative hybrids of L. alatum var. lanceolatum and L. curtissii have been noted in the vicinity of Leary, Calhoun County, Georgia.</p>
