|discussion=<p><i>Pinus strobus</i> is an important timber tree; because of extensive lumbering, few uncut stands remain. It was once prized as a source for ship masts, and large tracts of it were reserved for the Royal Navy during colonial times.</p><!--
--><p><i>Pinus strobus</i> var. chiapensis appears to be as Martínez saw it: a clinal variant that, compared to the type variety, has finer leaves, different resin canal distribution, and heavier cones when cones of similar sizes are compared.</p><!--
--><p>Eastern white pine (<i>Pinus strobus</i>) is the provincial tree of Ontario and the state tree of Maine and Michigan.</p>
