The bark is thick, with deep, longitudinal fissures and rough, elongated plates. On the upper part of the trunk and branches smooth to finally scaly. Greyish brown .The crown is loose and open.The branches are long and slender, swaying in the wind , spreading or curved downward, not pendulous, forming a rounded, dense or more open crown . The young twigs are bluish-green .The winter buds are narrow and sharp pointed, without resin and with loose scales, usually light-brown .The needles are (7-)9-13(-15) cm x 1-1.2mm bright lustrous green , bundled in threes and with a short basal sheath .
