Halocarpus bidwillii, commonly known as the mountain pine or bog pine, is a species of conifer in the family Podocarpaceae. It is endemic to New Zealand and can be found throughout the North and South Islands. It is an evergreen shrub favouring both bogs and dry stony ground, seldom growing to more than 3.5 m (11 ft) high.
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 cones take from four months to three years to reach maturity, and vary in size from 2 to 600 millimetres (1 ⁄ 8 to 23 + 5 ⁄ 8 in) long. In Pinaceae, Araucariaceae, Sciadopityaceae and most Cupressaceae, the cones are woody, and when mature the scales usually spread open allowing the seeds to fall out and be dispersed by the wind.
Needles and cones. The green pine needles give the twisted branches a bottle-brush appearance. The needles of the tree surround the branch to an extent of about one foot near the tip of the limb. [13] The name bristlecone pine refers to the dark purple female cones that bear incurved prickles on their surface.

The female cones (seed), which mature in autumn about 18 months after pollination, are globose, large, 18–25 cm (7–10 in) in diameter, and hold about 100–150 seeds. The cones disintegrate at maturity to release the approximately 5 cm (2 in) long nut -like seeds, which are then dispersed by animals, notably the azure jay , Cyanocorax ...
