Pinus johannis is a pine in the pinyon pine group, native to North America.

Pinus johannis is a small to medium-size tree, often just a shrub, reaching tall and with a trunk diameter of up to 50 cm.

As Robert-Passini and Bailey & Hawksworth were working in different areas at about the same time, it was raised to species rank twice, first as Pinus johannis by Robert-Passini ( naming it after her husband Jean ) examining specimens in the Sierra Madre Oriental in Mexico, and then later as Pinus discolor by Bailey & Hawksworth examining specimens in the northern Sierra Madre Occidental in Arizona.

P. johannis is most closely allied to Orizaba pinyon ( Pinus orizabensis ) and Potosi pinyon ( Pinus culminicola ), with which it shares the leaf structure with the stomata confined to the inner faces ; it differs from the former in the smaller cones and seeds, and from the latter in fewer needles per fascicle ( 3-4 vs 5 ).

The oldest recovered boat in the world is the Pesse canoe ; it is a dugout or hollowed tree trunk from a Pinus sylvestris.

The longest-lived is the Great Basin Bristlecone Pine, Pinus longaeva.

* Pine ( Pinus ) is a fast-growing wood grown commercially for use in construction and paper pulp industries.

Pine Valley is named for the locally unique stand of Jeffrey pine ( Pinus jeffreyi ) found along Pine Valley Creek, a seasonal drainage in the foothills of the Laguna Mountains in central San Diego County.

Vegetation in the basin is dominated by a mixed conifer forest of Jeffrey pine ( Pinus jeffreyi ), lodgepole pine ( P. contorta ), white fir ( Abies concolor ), and red fir ( A. magnifica ).

The Californian Gray Pine ( Pinus sabineana ) is named after him, as is Sabine's Gull ( Larus sabini ).

The bark of some trees is edible ; in Sweden and Finland, pine bread is made from rye to which the toasted and ground innermost layer of pine bark is added, the Sami people of far northern Europe used large sheets of Pinus sylvestris bark that were removed in the spring, prepared and stored for use as a staple food resource and the inner bark was eaten fresh, dried or roasted.

It is also conjectured that the process of carbon capture does not reach equilibrium, which along with no need of direct maintenance, makes kauri forests a potentially attractive alternative to short rotation Pinus radiata forests, for example.

In the pine forests, Montezuma Pine ( Pinus montezumae ) is generally predominant, with Hartweg's Pine ( Pinus hartwegii ) and Pinus teocote in dry areas with shallow soils.

However it is more tolerant than yellow-poplar ( Liriodendron tulipifera ), black cherry, and shortleaf pine ( Pinus echinata ).

Scots Pine ( Pinus sylvestris ) is a species of pine native to Europe and Asia, ranging from Scotland, Ireland and Portugal in the west, east to eastern Siberia, south to the Caucasus Mountains, and as far north as well inside the Arctic Circle in Scandinavia ( including Sápmi ).

Pinus sylvestris is an evergreen coniferous tree growing up to 35 m in height and 1 m trunk diameter when mature, exceptionally to 45 m tall and 1. 7 m trunk diameter and on very productive sites ( in Estonia, there are some 220 year old trees that are 46 metres tall in the forests of Järvselja ).

The isthmus is mostly covered by coniferous forests formed by Scots pine ( Pinus sylvestris ) and Norway spruce ( Picea abies ), with numerous lakes ( e. g. Lake Sukhodolskoye and Lake Glubokoye ) as well as small grass low moors and Sphagnum peat bogs.

In this forest there is a family recreation area and a local shelter a group of monkeys: long-tail macaque ( Macaca fascicularis ) and monkey ( Macaca nemistriana ) under the Sumatran Pine wood ( Pinus mercussi ).

The provincial tree is the Khasi Pine ( Pinus kesiya ).

The isolated Cerro Potosí population is strongly associated with the local endemic Potosi Pinyon Pinus culminicola.

Clark's Nutcracker is the primary seed disperser for Whitebark Pine ( Pinus albicaulis ).

It is a bird of warm, dry, open country with scattered trees, preferring lowland open countryside with patches of oak Quercus forest, mature pine Pinus woodland with heathery clearings, orchards, mixed farmland, river valleys, and plains with scattered thorny or leafy trees.

A common " foreign " species is the Monterey pine ( Pinus radiata ), which was uncommon in Big Sur until the late 19th century, when many homeowners began to plant it as a windbreak.

The most recently described species, A. salvaterrensis, was found in Pinus pinaster forests in Galicia ( northwest Iberian Peninsula ).

Over 100 Pinus sylvestris varieties have been described in the botanical literature, but only three or four are now accepted ; they differ only minimally in morphology, but with more pronounced differences in genetic analysis and resin composition.

The extinct pine species Pinus matthewsii has been described from Pliocene sediments in the Yukon areas of the refugium.

A pine from the Dabie Shan mountains in Anhui, eastern China, first described as a species Pinus dabeshanensis, is occasionally treated as a variety of this species, but more commonly as a variety of P. armandii, which it more closely resembles.

So when two botanists from California found a distinct tree in western Nevada in 1948 with some marked differences from the Ponderosa Pine they were familiar with in California, they described it as a new species, Washoe Pine, Pinus washoensis.

The species was first described as Pinus heldreichii by the Swiss botanist K. Hermann Christ in honor of Theodor von Heldreich in 1863 from specimens collected on Mount Olympus, and then described a second time as P. leucodermis in 1864 ; the author of the second description ( the Austrian botanist F. Antoine who found it on Orjen above the Bay of Kotor ) being unaware of the slightly earlier publication by Christ.

is closely related to the Tenasserim Pine-Pinus latteri, which occurs further north in southeast Asia from Myanmar to Vietnam ; some botanists treat the two as conspecific ( under the name Pinus merkusii, which was described first ), but Pinus latteri differs in longer ( 18-27 cm ) and stouter ( over 1 mm thick ) leaves and larger cones with thicker scales, the cones often remaining closed for some time after maturity.

Tenasserim Pine, Pinus latteri, is closely related to Sumatran Pine Pinus merkusii, which occurs further south in Southeast Asia in Sumatra and the Philippines ; some botanists treat the two as conspecific ( under the name P. merkusii, which was described first ), but the Sumatran Pine differs in shorter ( 15-20 cm ) and slenderer ( under 1 mm thick ) leaves, smaller cones with thinner scales, the cones opening at maturity, and seeds only half the weight.

This species was previously described as a subspecies of Pinus balfouriana ( Pinus balfouriana aristata ).
