The two species in the flora area are rather similar and frequently have been misidentified in the past; they differ in the shape of the leaf base, the number, size, and distribution of alar cells, the shape and stance of the leaves, and the branching pattern. The leaf base characters are most useful, but can be distinguished reliably only by the distal stipe or stem leaves. There are many misidentifications in exsiccatae issued by W. Bauer and by A. J. Grout, and material annotated by C. B. Arzeni and by E. Britton. Distributions of the species differ in the flora area; elsewhere, their ranges overlap.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Stems branched; branch leaves weakly seriate; distal stipe leaf bases often auriculate, weakly to strongly rounded, not decurrent; alar cells indistinct or (especially in auriculate plants) in 1 or 2 rows of few cells, irregular-quadrate, not reaching margin. |[[Pireella pohlii|Pireella pohlii]] |-id=key-0-1 |1 |Stems simple or sparsely branched; branch leaves strongly seriate; distal stipe leaf bases not auriculate or rounded, decurrent; alar cells in 7-14 rows of 2-23 cells, quadrate or short- rectangular, into decurrent wing and along margin. |[[Pireella cymbifolia|Pireella cymbifolia]] |} </div></div><!-- -->{{#Taxon: name=Pireella |author=Angela E.
