The young branches are smooth and gray-green or glaucous. The male cones are ovoid, yellowish, gathered in spikes that release the pollen in the period of June; the female cones are green-glaucous, cylindrical, supported by a long peduncle, long at maturation up to 30 cm light brown, pendulous and curved, very resinous; the cones have scales with large apophysis furrowed and terminating in obtuse umbons.
