説明

<jats:p> Quantitative photographic evidence is presented indicating that in the sensitive plant <jats:italic>Schrankia microphylla</jats:italic> the leaf-folding response that accompanies the sensitive reaction results in a pronounced increase in thorn exposure. It is argued that in sensitive plants that are thorny, including other species of <jats:italic>Schrankia</jats:italic> , as well as <jats:italic>Mimosa pudica</jats:italic> , the plant in which the sensitive reaction is traditionally demonstrated, leaf folding may be a defensive adaptation. </jats:p>
