Araucaria cunninghamii var. papuana Laut.
Common NamesNew Guinea hoop pine (1).Taxonomic notesSyn: A. beccari Warb. (1).Description"A tree 22-60 m. tall, to 1 m. in girth, with symmetrical branches. Bark peeling off in thin rolls. Leaves acute, 1 cm. long by 2.5 mm. wide, keeled on both faces, apex recurved and spine-tipped. Male cone relatively short, 2.5 cm. long by 0.5 cm. wide. Female cone to 11 cm. long, bracts black and longer. Seeds shorter and broader with larger wings, nut 8 mm. wide, wing 10 mm. wide, entire seed 2.5 cm. long by 3.5 cm. wide" (1).RangeW New Guinea: Papua New Guinea westwards, 610-2400 m (1). It often occurs in conjunction with A. hunsteinii. Compared to A. hunsteinii, A. cunninghamii has a dispersed regeneration pattern beneath a closed canopy (rather than relying on gap-phase regeneration) and typically occurs on wetter, less nutrient-rich sites, despite which it maintains higher productivity (3, 4).Big TreeOldestDendrochronologyEthnobotanyObservationsRemarks"In the Owen Stanley Mountains [of Papua New Guinea] a National Park shared between several Provinces (Central, Oro and Milne Bay) should be established. It should include the high altitude areas of the Owen Stanley Ranges, in particular Mts. Albert Edward, Tafa, Scratchley, Obree, Victory (local name: Kerorova), Dayman, and Suckling. The area is of exceptional biological interest with a great variety of plant and animal species. For example ... because of its natural stands of Hoop and Klinkii pine trees. In conclusion there are strong reasons to propose the Owen Stanley Ranges for World Heritage Area listing" (2).See also: the "Remarks" section of A. hunsteinii.
