Abies numidica (Algerian fir) is a species of fir found only in Algeria, where it is endemic on Djebel Babor, the second-highest mountain (2,004 meters) in the Algerian Tell Atlas.[1][2][3]

Description[edit]

Abies numidica is a medium-sized to large evergreen tree growing to 20–35 meters tall, with a trunk up to 1 meter diameter. The leaves are needle-like, moderately flattened, 1.5–2.5 centimeters long and 2–3 millimeters wide by 1 millimeters thick, glossy dark green with a patch of greenish-white stomata near the tip above, and with two greenish-white bands of stomata below. The tip of the leaf is variable, usually pointed, but sometimes slightly notched at the tip, particularly on slow-growing shoots on older trees. The cones are glaucous green with a pink or violet tinge, maturing brown, 10–20 centimeters long and 4 centimeters broad, with about 150–200 scales, each scale with a short bract (not visible on the closed cone) and two winged seeds; they disintegrate when mature to release the seeds.[2]

Distribution[edit]

Abies numidica grows in a high-altitude Mediterranean climate at 1,800–2,004 meters (and rarely down to 1,220 meters) with an annual precipitation of 1,500–2,000 milliliters, the great majority of which falls as winter snow; the summers are warm and very dry. It is closely related to Abies pinsapo (Spanish fir), which occurs further west in the Rif mountains of Morocco and in southern Spain.[2]

Cultivation and uses[edit]

Algerian fir, Abies numidica, is occasionally grown as an ornamental tree in parks and larger gardens. It is valued among firs for its drought tolerance.
