Pinus nigra black pine

A two-needled pine with stiff, dark-green needles, quite uncommon in California landscapes. Nigra means black, referring to the dark gray bark, much darker than that of P. sylvestris, alongside which it is often found.

Professor Ron Bracewell had noted some Austrian black pines (subsp. nigra) to the right of the stairs on the east side of the former ΣAE house at 1047 Campus Drive, though none remain at that spot.
