|discussion=<p><i>Eleocharis parishii</i> is very similar to <i>E. montevidensis</i>, with which it sometimes grows. It differs from <i>E. montevidensis</i> mainly in its narrowly lanceoloid to cylindric spikelets and its floral scale apices not recurved or horizontally wrinkled. Some apparent intermediates occur in regions of sympatry. The floral scales of <i>E. montevidensis</i> are more densely placed on the rachilla.</p>
