Pinus albicaulis (Whitebark Pine)

Pinus albicaulis

Native: Western North America at altitudes between 1500-3000m

A small tree, reaching heights of about 15m or a low shrub about 3m in exposed sites. The edible sweet seeds were collected for food by American Indians.

Foliage

Needles are in bundles of five, sometimes six, or rarely eight, with pale lines on all surfaces 5cm-6cm long. Leaf buds are dark reddish-brown, with scales closely pressed.

Pollen and Seed Cones

Pinus albicaulis

Cones open in June, males red and clustered, females red, about 12mm long.

Mature Cones

Pinus albicaulis

Mature cones are about 4cm to 8cm with thick scales bearing sharp spines and ripening from purple to brown. They fall from the tree, eventually breaking up to release unwinged, edible seeds, about 12mm long.
