Leaves are evergreen in clusters of 2, 2-4" long, thin, straight or slightly twisted, medium green. Generally pointing forward on the stems, they don't seem to be retained for very many years. Have seen a few clusters with 3 needles.
2 needle pines here:
P. cembrioides, very short needles, small tree, tiny cones with pinyon seeds.
P. controta, has very short leaves and very much smaller cones, not really common.
P. densiflora has very thin leaves and every much smaller cones as well as being clustered, less common as well.
P. halepensis has thin leaves, found on the freeways usually.
P. mugo, small shrub generally,
P. nigra, leaves dark, stiff, white buds, yellowish tan cones,
P. pinea, leaves thicker, stiffer, look for the leaves on new shoots on this one to be laying almost flat and forward as well as being retained longer.
P. sylvestris, bluish green leaves, distinctly twisted, smaller cones, reddish bark, not common.
P. thunbergii, thicker needles, often yellowish green, very sharp and usually twisted.
