|discussion=<p>Pseudoleskea patens is relatively small and usually dull, dark, or olive green, with short laminal cells with rounded centrally located papillae; it differs from P. tribulosa by the recurved margins, weaker and lower laminal cell papillae lacking projecting apical salient, larger leaves with stronger plicae, and lack of the Morningstar-shaped projections of the abaxial apex cells of the costa.</p>
