CONES: Seed cones small with soft scales. The seeds, nestled between the
scales, have a papery, three-pointed wing exposed from between the scales.
LEAVES: Leaves are slightly flattened needles not in fascicles - arrayed
singly along the stems and arrayed more-or-less equally around the stem.
Aromatic when crushed like fresh pine.
TREE: Reaches rather large proportions in Arizona (40m) in old-growth
forest (even taller in Northwest forests). But in most areas that are easily
accessible, second growth, smaller trees prevail.
RANGE: Widespread in the upper half of the elevational range of
ponderosa in Arizona and extending into the lower spruce zones. Widespread
across the Mountains of western North America south into northern Mexico.
UNARMED. Thornless.
