Picea abies, the Norway spruce or European spruce, is a species of spruce native to Northern, Central and Eastern Europe. It has branchlets that typically hang downwards, and the largest cones of any spruce, 9–17 cm (3 1 ⁄ 2 – 6 3 ⁄ 4 in) long. It is very closely related to the Siberian spruce (Picea obovata), which replaces it east of the Ural Mountains, and with which it hybridises Clade: Tracheophytes. Dec 01, · Abstract.
