''Pinus strobiformis'', a member of the [[Pinus classification|white pine]] group, ''[[Pinus]]'' subgenus ''[[Strobus]]'', is a straight, slender tree growing to {{convert|30|m}} (rarely {{convert|40|m}}) tall and {{convert|1|m}} in diameter. The [[bark (botany)|bark]] is smooth and silvery-grey on young trees, aging to furrowed and red-brown or dark grey-brown. The branches are spreading and ascending. The twigs are slender, pale red-brown, aging to smooth grey or grey-brown. The buds are ellipsoid, red-brown, and resinous. The [[Leaf|leaves]] (needles) are five per bundle ([[Fascicle (botany)|fascicle]]), spreading, 8–14&nbsp;cm long, 0.6-1.0&nbsp;mm in diameter, straight, slightly twisted, pliant, dark green to blue-green, and persist 3–5 years. The upper surfaces (adaxial, facing the centre of the fascicle) is conspicuously whitened by narrow [[stomatal]] lines. The lower surfaces (abaxial, the outer face away from the centre of the leaf fascicle) are without evident stomatal lines. The margins are sharp, razorlike and finely serrulate, apex narrowly acute to short-subulate. Each fascicle has a [[deciduous]] [[leaf sheath|sheath]] 1.5-2.0&nbsp;cm long which is shed early.

The cones are very large, 16–50&nbsp;cm long and 9–11&nbsp;cm broad, and have scales with a very characteristic prolonged and often recurved or S-shaped apex. The seeds are large, and with a very short wing; they are dispersed mainly by [[bird]]s, particularly the [[Mexican jay]].
