|discussion=<p><i>Krigia biflora</i> is known from the Eastern deciduous forest biome, tallgrass prairie, Rocky Mountain forest, and Madrean woodlands. It appears to spread clonally by adventitious buds on the roots. It is related to the more leafy-stemmed, freely branching <i>K. montana</i> (K. J. Kim and B. L. Turner 1992); their habital differences are less clear where they are sympatric in the southern Appalachians. An alloploid hybrid between them has become established (see 3. <i>K. montana</i>).</p>
