Pinus coulteri
Coulter pine

Pinaceae (pine family)
California
Pinus coulteri cone, needles, seeds. From: George B. Sudworth, Forest Trees of the Pacific Slope

Coulter pine is conspicuous by its large cones (it is often called bigcone pine) that may be over a foot long and are covered with long, wicked, incurving claws. The needles are in threes, about 9 inches long and have a deep bluish tinge. Coulter pine is widespread in the coast ranges of Southern California, but is also common in the Santa Lucia Mountains just south of Monterey, and reaches as far north as the Bay Area. The cone scales have a rather attractive two-tone coloration. Why this native has not been accorded more respect on campus is a mystery.

A mature specimen is 40 feet west of the ΣAE parking lot on Campus Drive East, among a group of P. halepensis. It is named for the Irish botanist Thomas Coulter (1793–1843).
