Pinus lambertiana (commonly known as the sugar pine or sugar cone pine) is the tallest and most massive pine tree, and has the longest cones of any conifer. The species name lambertiana was given by the British botanist David Douglas, who named the tree in honour of the English botanist, Aylmer Bourke Lambert. It is native to the mountains of the Pacific coast of North America, from Oregon through California to Baja California.
The sugar pine is the tallest and largest Pinus species, commonly growing to 40–60 meters (130–195 ft) tall, exceptionally to 82 m (269 ft) tall, with a trunk diameter of 1.5–2.5 m (4 ft 11 in–8 ft 2 in), exceptionally 3.5 m (11 ft 6 in). The tallest recorded specimen is 83.45 metres (273 ft 9 in) tall, is located in Yosemite National Park, and was discovered in 2015. The second tallest recorded was "Yosemite Giant", an 82.05 m (269 ft 2 in) tall specimen in Yosemite National Park, which died from a bark beetle attack in 2007. The tallest, known, living specimens today grow in southern Oregon and Yosemite National Park: one in Umpqua National Forest is 77.7 m (254 ft 11 in) tall and another in Siskiyou National Forest is 77.2 m (253 ft 3 in) tall. Yosemite National Park also has the third tallest, measured to 80.5 m (264 ft 1 in) tall as of June 2013; the Rim Fire affected this specimen, but it survived.
Pinus lambertiana is a member of the white pine group, Pinus subgenus Strobus, and, like all members of that group, the leaves ("needles") grow in fascicles ("bundles") of five, with a deciduous sheath. They are 6–11 cm (2 1⁄4–4 1⁄4 in)ch) long. Sugar pine is notable for having the longest cones of any conifer, mostly 25–50 cm (9 3⁄4–19 3⁄4 in) long, exceptionally to 66 cm (26 in) long, although the cones of the Coulter pine are more massive. The seeds are 10–12 mm (13⁄32–15⁄32 in) long, with a 2–3-centimeter (3⁄4–1 1⁄8-inch) long wing that aids their dispersal by wind. The seeds of the sugar pine are also a type of edible pine nut.
