|discussion=<p><i>Pseudoleskea atricha</i> is a local high elevation endemic species characterized by ovate leaves with an acute but not acuminate apex, and incrassate laminal cells that are strongly pitted. Only <i>P. baileyi</i> also has strongly pitted cells, but it differs in having leaves with long acumina and hair-points, and stems lacking paraphyllia.</p>
