Description
Araucaria cunninghamii is a tall, evergreen coniferous tree, usually 20–60 m tall, occasionally reaching over 70 m in its native forests. It possesses a straight cylindrical trunk with grey to dark brown, rough, fissured bark that peels in thin scales. The crown is narrowly conical in young trees, becoming more open and irregular with age. Branches are arranged in regular horizontal whorls, forming a symmetrical pyramidal habit. Leaves are simple, spirally arranged, stiff, leathery, and glossy green. Juvenile leaves are awl-shaped and sharply pointed, whereas adult leaves are smaller, triangular to lanceolate, and closely appressed to the branchlets. The species is monoecious, producing separate male and female cones on the same tree. Male cones are long, cylindrical, and pendent, while female cones are globose to ovoid, woody, and borne near the ends of upper branches. At maturity, the female cones disintegrate to release numerous winged seeds.

Taxonomic Notes
Araucaria cunninghamii, commonly known as the Hoop Pine, is one of the most important timber-producing species of the family Araucariaceae. It is readily distinguished by its tall, straight trunk, regular whorled branches, narrow pyramidal crown, and rough, fissured bark. Unlike Araucaria heterophylla (Norfolk Island Pine), the branches of A. cunninghamii are generally less densely layered, and mature trees develop a more open crown. The species is recognized as an accepted taxon in Flora of Pakistan, Plants of the World Online (POWO), and World Flora Online (WFO).
