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. The branch with staminate cones shows the leaves in fascicles of four or five. This site is in the Tyndall Creek area south of Forester Pass.
Scotts Pine (Pinaceae) - Alice Holt, Farnham, Surrey.
The genus Pinus (Pines) has leaves (needles) which have shoots with bunches of 2, 3, or 5 leaves, each bunch enclosed in a sheath of papery bracts. The number of needles helps identification, but occasionally there are bunches with a nonstandard number of leaves, so several shoots need to be examined. Cones are mostly more or less egg-shaped (ovoid) with hard, woody scales.
P. sylvestris is probably UK's most common Pine and the only native one (in Scotland). Leaves are in bunches of 2, glaucus, 4-10cm long, broad and with a twist; well branched trunk with orangey-red bark in upper parts; cone scales without prickle on outer face.

Pinus edulis, the state tree of New Mexico, is common to the Taos area. Perhaps most similar to the Mexican Pinus cembroides in having mostly 2 (3) needles per fascicle, the leaves of Pinus edulis are over 1 mm in width. This region that descends in elevation from Taos to Española transitions out of the expanses of sagebrush steppe and is essentially devoid of Bromus tectorum. This site lies along highway 68 just to the southwest of Taos, Taos County, New Mexico, about where the highway and the Rio Grande meet.
"Pinus strobus 'Chippiannock' , 2016, Eastern [White Pine] Witches Broom, PYE-nus STROE-buss chip-eye -an-nock, 5x5? Conifer, Z4, blue-green needles, Bloom Month --, In Bed V1 for 4.2 years
Grafted at MSU class on Jan 28, 2012. Witch’s broom. A broad globular plant. Discovered ~1980 in Chippiannock Cemetery, Rock Island, IL by Randy Dykstra & Chub Harper."
Similar to the Ponderosa Pine but with a larger cone and inhabiting the Sierra Nevada especially along the eastern flank and central drainages. This area lies along Woods Creek just north of the Woods Creek crossing.

In young roots, the vascular cylinder is surrounded by two rings of cells, the pericycle and endodermis, and above these layers the cortex and epidermis. In older roots underling activity of the cork cambium replaces epidermal and a portion of cortical tissues with a protective zone of cork rich periderm.
A well developed cortex of 4 to 5 layers of thin-walled parenchymatous cells contains clusters of sclerenchymatous stone cells and small resin canals.
The inner-most layer of the cortex is marked by a single- layered endodermis of brown suberized cells containing dark staining tannin.
Just below the endodermis is a multi-layered pericycle containing tannin and starch grains.
The vascular cylinder or stele consists of an outer narrow ring of phloem,and deep to this, the vascular cambium. The vascular cambium produces annual growth of secondary phloem towards the outside of the root and secondary xylem towards center of the root. Crushed primary phloem is present outside the secondary phloem. Because of greater production of xylem, the bulk of the vascular cylinder is dominated by radially arranged rays of secondary xylem interspaced with medullary rays of parenchyma cells. Annual growth rings of spring and summer wood is difficult to distinguish in roots . The xylem has no true vessels, consisting entirely of tracheids. The phloem consists of sieve tubes and phloem parenchyma, lacking companion cells.
The center of the root is occupied by small degenerated pith surrounded by primary xylem and large resin canals.
