Conservation status

Abies fanjingshanensis

W.L. Huang, Tu et Fang 1984

Common names

Fanjingshan fir, 梵净山冷杉 fanjingshan lengshan [Chinese].

Taxonomic notes

It is closely related to A. fargesii (Farjon 1990), although the populations are separated by 500 km at their closest approach (Conifer Specialist Group 1998).

Syn.: Abies fargesii Franchet var. fanjingshanensis (W. L. Huang et al.) Silba 1990.

Description

Trees up to 20 m tall and 65 cm dbh. Bark dark gray. Branchlets red-brown, darkening in 2nd or 3rd year. Leaves radially spreading or ascending on upper side of branchlets, pectinately arranged in 2 lateral sets on lower side, linear, unequal, apex obtuse, 1-4.3 cm × 2-3 mm, stomata in 2 bands on lower side of leaves; resin canals 2, marginal on vegetative branchlets, median on cone-bearing branchlets. Seed cones shortly pedunculate, purple-brown, ripening dark brown, cylindric, 5-6 × ca. 4 cm. Seed scales reniform, ca. 1.5 × 1.8-2.2 cm, exposed part densely pubescent. Bracts spathulate, ca. 4/5 as long as seed scales, distal margin rounded or emarginate, apex with an acute, small cusp. Seeds slightly appressed, narrowly ovoid, ca. 8 mm; wing broadly cuneate, ca. 7 mm (Wu and Raven 1999). See also Farjon (1990).

Distribution and Ecology

China: NE Guizhou, Jiangkou Xian, on the northern slopes of Fanjing Shan (Wuling Shan). This location is at least 500 km to the south of the nearest occurrence of Abies fargesii in the northwestern part of Hubei. It is found at 2100-2350 m elevation as a minor component of mixed conifer-hardwood forest with Tsuga chinensis, Acer flabellatum, Rhododendron hypoglaucum, Enkiartos chinensis, Prunus serrulata and other species (Farjon 1990, Conifer Specialist Group 1998, Wu and Raven 1999).

The entire population is estimated to number less than 250 trees. However, the area is relatively inaccessible and no immediate threats are apparent (Conifer Specialist Group 1998).
