Pinus in the context of "Amanita phalloides"

Araucaria ( /ærɔːˈkɛəriə/; original pronunciation: [a.ɾawˈka. ɾja]) is a genus of evergreen coniferous trees in the family Araucariaceae. While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed. There are 20 extant species in New Caledonia (where 14 species are endemic, see New Caledonian Araucaria), eastern Australia (including Norfolk Island), New Guinea, Argentina, Brazil, Chile and Uruguay.

The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree (Araucaria araucana). No distinct vernacular name exists for the genus. Many are called "pine", although they are only distantly related to true pines, in the genus Pinus.

Pinus peuce (Macedonian pine or Balkan pine) (Serbo-Croatian and Macedonian: молика, molika; Bulgarian: бяла мура, byala mura) is a species of pine native to the mountains of North Macedonia, Bulgaria, Albania, Montenegro, Kosovo, the extreme southwest of Serbia, and the extreme northwest of Greece, growing typically at (600-) 1,000-2,200 (-2,300) m altitude. It often reaches the alpine tree line in this area. The mature size is up to 35–40 m height, and 1.5 m trunk diameter. However, the height of the tree diminishes strongly near the upper tree line and may even obtain shrub sizes.

It is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. They are 6–11 cm long. Its pine cones are mostly 8–16 cm long, occasionally up to 20 cm long, green at first, becoming yellow-brown when mature, with broad, flat to downcurved scales. The 6–7 mm long seeds have a 2 cm wing and can be wind-dispersed, but are also very often dispersed by spotted nutcrackers.

Pinus ponderosa, commonly known as the ponderosa pine or western yellow pine, is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.

Pinus ponderosa grows in various erect forms in 16 western U.S. states as well as British Columbia in Canada and has been introduced in temperate regions of Europe and in New Zealand. It was first documented in modern science in 1826 in eastern Washington near present-day Spokane (of which it is the official city tree). On that occasion, David Douglas misidentified it as Pinus resinosa (red pine). In 1829, Douglas concluded that he had a new pine among his specimens and coined the name Pinus ponderosa for its heavy wood. In 1836, it was formally named and described by Charles Lawson, a Scottish nurseryman. It was adopted as the official state tree of Montana in 1949.

The Atlantic coastal pine barrens is a now rare temperate coniferous forest ecoregion of the Northeast United States distinguished by unique species and topographical features (coastal plain ponds, frost pocket), generally nutrient-poor, often acidic soils and a pine tree distribution once controlled by frequent fires.

Vranica (Serbian Cyrillic: Враница) is a mountain range in the Dinaric Alps of central Bosnia and Herzegovina, located between the town of Gornji Vakuf in the west and the town of Fojnica in the east, within the territory of the Federation. The highest peak is Nadkrstac at 2,110 metres (6,920 ft). Geologically, the Vranica range is part of the Dinaric Alps and formed largely of secondary and tertiary sedimentary rock, mostly limestone. Notable peaks are Nadkrstac (2110 m), Locika (2106 m), Rosinj (2059 m) and Scit (1949 m). Thick shrubs of Pinus Mugo replace mixed forest—mostly beech—above 1,400 m (4,600 ft). The typical karst characteristics of the nearby Herzegovina mountains is relatively absent in Vranica, which has relatively abundant water sources. Streams that source from these mountains are the Dragača in the east, the Vrbas in the west.

The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are sister to all other contemporary lineages of Hymenoptera and have many ancestral morphological features.

The extant species occur in the Northern Hemisphere, especially in boreal regions of the Holarctic, though there are a few Oriental species. Two genera and about 15 species occur in Europe. Considering additional fossil records from Australia, South Africa and Argentina, the extant species display a relict distribution. The species in the subfamily Xyelinae are associated with conifers (esp. Pinus and Abies), where the larvae feed on pollen or within buds. The larvae of the subfamily Macroxyelinae feed on the leaves of deciduous trees (various Juglandaceae and Ulmus).
