Mountain araucaria (Silba 1986).
"A columnar tree 10-40 m. tall. Branches numerous and spreading, 15-22 mm. in diameter. Bark dark brown or gray, exfoliating in thin strips or scaly. Juvenile leaves scale-like, non-flattened, ovate, lanceolate, 10 mm. long by 4-5 mm. wide, apex incurved. Adult leaves scale-like, bluntly acute to obtuse, ovate, 11-14 mm. long by 7-8 mm. wide, loosely imbricate, apex incurved, midrib prominent. Male cone cylindrical, 8-13.5 cm. long by 20-28 mm. wide, scales triangular, pollen sacs 12, microsporophylls triangular. Female cone 8-9 cm. long by 6-8 cm. wide; bracts short and acuminate, 5-10 mm. long. Seed to 3.2 cm. long, with oval wings and an elongated nut. Germination epigeal" (Silba 1986).
N New Caledonia, type near Canala, 200-1400 m (Silba 1986). Rigg (2005) describes how this species occurs on ultramafic soils in both maquis and as an emergent in upland rainforest. In both habitats it evidently regenerates more or less continuously in response to small-scale disturbances including fire (in maquis) and blowdown (in maquis and rainforest).
The IUCN reports that the population is facing a high risk of extinction in the wild due to a limited and severely fragmented distribution that is forecast to experience continued decline in extent of habitat, number of subpopulations, and number of mature individuals.
