|discussion=<p><i>Botrychium dissectum</i> is highly variable, even within the same population. In Florida and along the Gulf Coast, the extremely lacerate form is absent, and the blade segments are usually strongly angular, trowel-shaped, and dentate. In eastern Kentucky and central Tennessee in forested valleys, on shale and limestone soils, plants have narrowly linear, somewhat blunt-tipped segments with a more or less whitish gray central line above the veins. This variant, which grows with <i>B. dissectum</i>, may deserve recognition as a distinct species.</p>
