|discussion=<p><i>Tragia amblyodonta</i> is easily distinguished from other members of <i>Tragia</i> by the combination of usually triangular to subhastate leaf blades, gray-green coloration, and painfully stinging hairs. Both stomata diameter and pollen grain size of <i>T. amblyodonta</i> are larger than in any other North American species of <i>Tragia</i> (K. I. Miller and G. L. Webster 1967).</p>
