The cones of the bunya pine are some of the largest produced by the conifer family. The cones—which can grow to as much as 35 centimetres (14 in) in diameter when mature, and weigh up to 10 kilograms (22 lb)—can drop on unsuspecting passersby from heights of 40 metres (130 ft) or more. [ 45 ]

The seeds ( pine nuts , piñones , pinhões , pinoli , or pignons ) are large, 2 cm ( 3 ⁄ 4 in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 4–8 mm ( 5 ⁄ 32 – 5 ⁄ 16 in ...
Subfamily Piceoideae : cones are annual, without a distinct umbo, the cone scale base is broad, concealing the seeds fully from abaxial view, seed is without resin vesicles, blackish, the seed wing holds the seed loosely in a cup, leaves have primary stomatal bands adaxial (above the xylem) or equally on both surfaces.
Podocarpus (/ ˌ p oʊ d ə ˈ k ɑːr p ə s / [2]) is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m (3 to 82 ft) tall, known to reach 40 m (130 ft) at times.
Pinus albicaulis leaves are in fascicles (bundles) of five, and the cone is dark purple when immature (Mount Rainier National Park). Whitebark pine is a member of the white pine group, the Pinus subgenus Strobus, and the section Strobus; like all members of this group, the leaves (needles) are in fascicles (bundles) of five [5] with a deciduous sheath.
