gray-brown with irregular, scaly-plated ridges, on upper sections of trunk reddish, scaly.
dark brown, at maturity deeply furrowed, ridges becoming yellowish, of narrow, elongate, scaly plates.
spreading-ascending to spreading-descending;
twigs slender, red- or purple-tinged, often glaucous, aging red-brown to gray, rough.
straight to ascending;

cones maturing in 2 years, shedding seeds soon thereafter, persisting to 5 years, symmetric, lance-ovoid or lanceoloid before opening, ovoid when open, 3–7(–8)cm, dull red-brown, nearly sessile or on stalks to 1cm, scales rigid, with strong purple-red or purple-brown border on adaxial surface distally;
apophyses slightly thickened, slightly elongate;
umbo central, low-pyramidal, with slender, stiff prickle.
cones maturing in 2 years and shedding seeds soon thereafter, not persistent, terminal, sometimes curved, often asymmetric, lance-ovoid before opening, ovoid when open, 11–14cm, light dull brown, nearly sessile or short-stalked;

Pinus virginiana
Pinus engelmannii
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.

In general appearance Pinus engelmannii much resembles P. palustris with its short-persistent, long leaves (but in this species drooping) and in its tendency to form a grass stage. It has a deep taproot as do P. palustris and P. ponderosa.
