Abies nordmanniana
''Abies nordmanniana'', the Nordmann fir or Caucasian fir, is a fir indigenous to the mountains south and east of the Black Sea, in Turkey, Georgia, Russian Caucasus and northern parts of Armenia. It occurs at altitudes of 900–2,200 m on mountains with a rainfall of over 1,000 mm.
The current distribution of the Nordmann fir is associated with the forest refugia that existed during the Ice Age at the eastern and southern Black Sea coast. In spite of currently suitable climate, the species is not found in areas of the Eastern Greater Caucasus, which are separated from the Black Sea Coast by more than 400–500 km.
== Description ==
It is a large evergreen coniferous tree growing to 55-61 m tall and with a trunk diameter of up to 2 m. In the Western Caucasus Reserve, some specimens have been reported to be and even tall, the tallest trees in the Caucasus, Anatolia, the Russian Federation and the continent of Europe.
The leaves are needle-like, flattened, 1.8–3.5 cm long and 2 mm wide by 0.5 mm thick, glossy dark green above, and with two blue-white bands of stomata below. The tip of the leaf is usually blunt, often slightly notched at the tip, but can be pointed, particularly on strong-growing shoots on young trees. The cones are 10–20 cm long and 4–5 cm broad, with about 150–200 scales, each scale with an exserted bract and two winged seeds; they disintegrate when mature to release the seeds.
