|discussion=<p><i>Botrychium jenmanii</i> occurs in a variety of habitats. In hardwoods and especially pine woods, it is associated with <i>B. biternatum</i>; in open grassy places and lawns it is found with <i>B. lunarioides</i>. In many ways, <i>B. jenmanii</i> is intermediate between <i>B. biternatum</i> and <i>B. lunarioides</i>, and it is possibly their allopolyploid derivative (W. H. Wagner Jr. 1968). It is the only tetraploid among New World members of subg. Sceptidrium.</p>
