Abies fabri

Abies fabri, known as Faber's fir, is an evergreen conifer in the family Pinaceae, order Pinales, endemic to the mountainous regions of western Sichuan Province in southwestern China, where it is a dominant component of subalpine conifer forests at elevations between 2,800 and 4,000 metres. The species was named in honour of Ernst Faber, a German missionary and naturalist who collected plants in China during the late 19th century. Abies fabri is closely related to Abies delavayi and is sometimes treated as a variety or subspecies of that species, though it is more commonly accepted as a distinct species in modern taxonomic treatments. The tree grows to 25 to 40 metres in height, with a narrowly pyramidal crown. Its needles are flat, dark green and glossy above, with two broad white stomatal bands on the underside, densely arranged on the branchlets. The seed cones are erect, dark bluish-purple when young, cylindrical, and disintegrate at maturity, leaving only the central rachis on the tree. Abies fabri forms ecologically vital subalpine forest communities in western Sichuan alongside Picea brachytyla, Betula, and various rhododendrons at the forest margins. These forests provide critical habitat for giant pandas, golden monkeys, and an exceptional diversity of plant species. The area is part of the Hengduan Mountains biodiversity hotspot, one of the most species-rich temperate regions on Earth. Abies fabri faces threats from logging, but many populations occur within protected areas.
