|discussion=<p><i>Cyperus oxylepis</i> is easily recognized by its sticky leaves, culms, and bracts (in living plants), involute leaves,and golden brown spikelets. The ovate-lanceolate floral scales and the ellipsoid, brownish achene with a persistent beak distinguish <i>C. oxylepis</i> from other species with deciduous floral scales.</p>
