Pinus lambertiana
Pinus muricata
The largest species of the genus, Pinus lambertiana also has the longest seed cone in the genus. It is an important timber tree with harvest far exceeding regrowth. It is easily distinguished from P. monticola and P. strobus by its larger cones and thicker cone scales with larger seeds; it is somewhat less reliably distinguished by its leaves, which are slightly wider and more tapering-tipped and have some stomatal lines evident on the abaxial surfaces (the lines not evident in P. monticola and P. strobus). A "sugary" resin high in cyclitols exudes from the sweet-scented fresh-cut wood.

The several varieties described for Pinus muricata reflect the high variability in leaf characters and in degree of elaboration of apophysis and umbo in this species. The extremes can sometimes occur together.
Of conservation concern.
