Pinus aristata is distinguished from the other bristlecone pines to the west by leaves with the abaxial surface with a strong, narrow median groove and scales of the seed cone bearing a terminal slender prickle mostly 6-10 mm long (the other bristlecones lack this long aristate prickle). This site lies along the base of the south shoulder of Sante Fe Baldy, Santa Fe County, New Mexico.
Sugar pines makes one of the longest cones of the pine genus. This photo shows some immature female cones.
These trees are probably 3000-4000 years old. It is hard for a mere human to grasp that scale standing next to these ancient organisms.

Scientific name: Pinus x holfordiana
Common name: Holford pine
Family: Pinaceae
Holford Pine is easy to find thanks to the eye-catching 6-to 8-inch cones suspended from its branches. Needles are blue-green, 5-to 7-inches long and branches are usually pubescent (covered with down or hairs). In 1904, natural cross-pollination between Pinus ayacahuite (Mexican white pine) and Pinus wallichiana (Himalayan pine) resulted in a generation of seedlings. Thirty years later when the first cones were produced, it became clear that the young trees were distinctly different from both parents.
Distinguished from the bristlecone pine (Pinus longaeva) by the broadly attenuate (not rounded) base of the pine-cone, each scale of which has no terminal prickle or weak one to only 1 mm, and an amber color to the resin on the pinecone. This site lies along Woods Creek just north of the Woods Creek crossing.
Whitebark pine is widespread in the Teton Range at the upper elevation including on the high benches and shelve and ledges on rock faces where it co-dominates with subalpine fir (Abies lasiocarpa). During the summer of 2016, the abundant cone crop was apparently produced high in the tree and these were foraged in part by squirrels.
Calabrian Pine, usually 2 needles, sometimes listed as a var. of P. halapensis, Arboretum Conifer Collection, UC Davis
Distinguished from the bristlecone pine (Pinus longaeva) by the broadly attenuate (not rounded) base of the pine-cone, each scale of which has no terminal prickle or weak one to only 1 mm, and an amber color to the resin on the pinecone. This pine species epitomizes the many stately conifer tree species of the Sierra Nevada. Along the John Muir Trail, this pine tree is common from south of Mount Whitney in the New Army Pass area north to somewhere just north of Mather Pass. It was not observed north of the Le Conte Canyon area. This site is sits below Mount Guyot in the Guyot Creek drainage.
