Araucaria bernieri

J.Buchholz 1949

Common names

Bernier's araucaria (Silba 1986).

Taxonomic notes

Synonym: Eutassa bernieri (J.T. Buchholz) de Laub. 2009. A molecular analysis places Araucaria bernieri into the clade of small-leaved species of New Caledonia, along with A. schmidii, A. scopulorum, and A. subulata (Gaudeul et al. 2012).

Description

Trees to 50 m tall with a narrowly columnar crown. Bark gray, exfoliating in thin strips. Twigs in one plane, forming a wide U-like pattern, 4-6 mm in diameter. Juvenile leaves triangular, needle-like, apex sharply acute, to 7 mm long, relatively thick. Adult leaves scale-like, imbricate, triangular, keeled, 2-3.5 × 1.5-2.5 mm, apex incurved. Pollen cone bluish-white, cylindrical, 40-90 mm × 8-16 mm, scales lanceolate, microsporophylls triangular, pollen sacs 4-6. Seed cone glaucous, 10 × 7.5-8 cm, recurved lip of scale raised, bracts to 5 mm long. Seeds to 3 cm long, nuts ovate, wings broadly rounded. Germination epigeal (Silba 1986).

Distribution and Ecology

New Caledonia: Grande Terre, restricted to the extreme S and on uplands along the SE coast, south of 21.5°S (Farjon et al. 2014).

This map shows herbarium records of Araucaria species native to New Caledonia. Letter corresponds to first letter of species epithet (A. goroensis coded as A. muelleri, see A. goroensis for discussion) with different colors for species having same first letter; A. bernieri is light green. Click on an icon for further information. Distribution data from GBIF (2020.03.30), edited to remove duplicates.

The IUCN reports that this species is facing a high risk of extinction in the wild due to a small population size (fewer than 10,000 mature individuals) that is suffering ongoing and projected continuing population declines.
