|discussion=<p>In North America Asplenium septentrionale is principally a western species with isolated disjunct populations in Monroe and Hardy counties, West Virginia. Because of its close resemblance to a tuft of grass, it is easily overlooked, and discoveries of additional localities are to be expected. In Europe A. septentrionale is known to hybridize with several species, but in North America only the hybrid with A. trichomanes (A. × alternifolium Wulfen) is known.</p>
