|discussion=<p><i>Pellaea breweri</i> is distinguished from other North American taxa (except for some populations of <i>P. glabella</i>) by the presence of prominent articulation lines near the base of the petiole. The leaves are easily detached, and many herbarium specimens consist of separate leaves and stems, the latter covered with petiole bases of approximately equal length.</p>
