Pinus nigra black pine

A two-needled pine with stiff, dark-green needles, quite uncommon in California landscapes, though other pines are sometimes mistaken for it. Nigra means black, referring to the dark gray, plated bark of mature trunks – much darker than that of P. sylvestris, with which it often grows in habitat.

In 2005, Professor Ron Bracewell had noted some Austrian black pines (subsp. nigra) right of the stairs on the east side of the former ΣAE house at 1047 Campus Drive, though only P. brutia, P. halepensis, and P. torreyana have been seen around that spot since.
