The stone pine is a coniferous evergreen tree that can exceed 25 metres (80 feet) in height, but 12–20 m (40–65 ft) is more typical. In youth, it is a bushy globe, in mid-age an umbrella canopy on a thick trunk, and, in maturity, a broad and flat crown over 8 m (26 ft) in width. [ 2 ]

A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
The species was first described by Linnaeus in 1753 in his book Species Plantarum [1] There are six recognized subspecies, originally named by Tolken, [2] as follows: . C. tetragona subsp. acutifolia, stems decumbent, rooting at internodes, and sharply acute leaf apices.
The roots have nitrogen-fixing nodules. [2] It grows into a small tree of up to 7 m (23 ft) tall. Mature trees bear cone–structure fruits 7–15 mm (0.3–0.6 in) long X 8–15 mm (0.3–0.6 in) wide. When ripe the cone's numerous valves open to release the dark–coloured winged seeds 7–8 mm long. [2] [5] [6]
