|discussion=<p>The name "rugulosum" refers to the tendency of the segments to become more or less wrinkled and convex. <i>Botrychium rugulosum</i> occurs with <i>B. dissectum</i>, <i>B. multifidum</i>, and rarely <i>B. oneidense</i>. It is often found in small stands of only 5–10 individuals, but some populations number over 100.</p>
