Pinus flexilis
Pinus virginiana
Pinus flexilis, much branched with a strongly tapering trunk, is little utilized because of its form and relative inaccessibility. It reportedly forms intermediates with P. strobiformis where the two overlap. The fresh-cut wood has the odor of turpentine.

Pinus virginiana is weedy and fire successional and often forms large stands. It is mostly too small and too profusely branched to be valued except as pulpwood.
