|discussion=<p><i>Euphorbia laredana</i> is similar to <i>E. prostrata</i> but differs from that species in its more densely tomentose indumentum, leaves with usually entire rather than serrulate margins, and slightly longer seeds with rounded rather than sharp ridges. The species occurs primarily in southern Texas.</p>
