Araucaria columnaris

(Cook Pine)

Overview

[ Back to top ]

Large tree from New Caledonia (Pine Island) discovered by Captain Cook with a columnar , cone-shaped crown to 200 feet in height and scale-like leaves about a quarter of an inch long. The male cones (4) are papery in texture and remain intact but the larger female cones (5) are woody and separate into thick, one-seeded scales . Trees are very suitable for reforestation and are useful for lumber and masts. The Norfolk Island Pine A. heterophylla is very similar, especially when immature .

Family Araucariaceae

Trees evergreen , dioecious or monoecious, with relatively large pith in trunk and resin in cortex. Leaves spirally arranged or decussate, sessile, decurrent. Cones unisexual . Pollen cones axillary or terminal on branchlets , solitary or clustered; microsporophylls numerous , spirally arranged, sessile; microsporangia 4-20, external, suspended, arranged in 2 rows , filiform ; pollen sacs split longitudinally; pollen nonsaccate. Seed cones solitary, terminal on branchlets, maturing in 2nd or 3rd year; bracts numerous, spirally arranged; ovulate scales degenerate or ligulate , connate with bracts on 1 side, each with 1 ovule at base abaxially; ovules connate with ovulate scales or with bracts (when ovulate scales degenerate) ; bracts of mature cones deciduous, flattened, woody or thickly leathery, bearing 1 seed in basal part (if developed), sometimes adnate with ligulate seed scales in center of adaxial surface, apex triangular or caudate . Seeds connate with bracts or detached, flattened, winged or not. 2n = 26.

Three genera and 41 species: Indonesia, Malaysia, Papua New Guinea, Philippines; Australia, New Zealand, SW Pacific Islands, South America; two genera and four species (all introduced ) in China.[1]

Genus Araucaria

Trees monoecious, occasionally dioecious; branches whorled or almost so; winter buds small. Leaves spirally arranged , needlelike to broadly ovate or triangular, varied in shape and size even on same tree. Pollen cones axillary or terminal on branchlets , cylindric , ovoid , or ellipsoid ; microsporophylls densely arranged. Seed cones erect , ellipsoid, or ovoid to subglobose; ovulate scales ligulate ; bracts of mature cones large, woody, distal part thickened, distal margin sharply and transversely ridged , apex reflexed or upcurved, pointed ; seed scales adnate with bracts in basal, seed-bearing part, detached in apical part, sometimes thickened and exposed. Seeds connate with bracts, sometimes with 2 apparent lateral wings formed from bract. Cotyledons usually 2, occasionally 4. Germination hypogeal or epigeal.

Nineteen species: Papua New Guinea; Australia (including Norfolk Island), New Caledonia, South America; three species (introduced ) in China.[2]
