Silje Nes chooses
Folk singer Silje Nes thinks so much about nature that she could think of no better top 10 list than one of her favourite tree names.
Family FagaceaeAn oak is a tree or shrub in the genus Quercus (pronounced /?kw?rk?s/; Latin "oak tree"), of which about 600 species exist on earth. "Oak" may also appear in the names of species in related genera, notably Lithocarpus. The genus is native to the northern hemisphere, and includes deciduous and evergreen species extending from cold latitudes to tropical Asia and the Americas.
Family Betulaceae Birch species are generally small to medium-size trees or shrubs, mostly of temperate climates. The simple leaves may be toothed or pointed. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders ( Alnus, other genus in the family) in that the female catkins are not woody and disintegrate at maturity, falling apart to release the seeds, unlike the woody cone-like female alder catkins.
Family AceraceaeMaples are distinguished by opposite leaf arrangement. The leaves in most species are palmate veined and lobed, with 3 to 9 (rarely to 13) veins each leading to a lobe, one of which is central or apical. A small number of species differ in having palmate compound, pinnate compound, pinnate veined or unlobed leaves.
Family ArecaceaePalms have large evergreen leaves that are either palmately ('fan-leaved') or pinnately ('feather-leaved') compound and spirally arranged at the top of the stem. The leaves have a tubular sheath at the base that usually splits open on one side at maturity. The inflorescence is a panicle or spike surrounded by one or more bracts or spathes that become woody at maturity. The flowers are generally small and white, radially symmetric, and can be either uni- or bi-sexual.
Family CupressaceaeSequoia is a genus of redwood coniferous trees in the Sequoioideae subfamily, of the Cupressaceae family. The only extant species of the genus is the Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southern Oregon in the United States. The two other genera, Sequoiadendron and Metasequoia, in the subfamily Sequoioideae are closely related to Sequoia.It is one of the largest trees in California
Family SalicaceaeWillows all have abundant watery bark, sap which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to life, and roots readily grow from aerial parts of the plant.
Family Myrtaceae Eucalypts are attuned to withstand fire in several ways: Their seeds are often held in an insulated capsule, which is only opened in response to and after the devastation of a bushfire. Once cooled down, it is a freshly fertilised seed bed. Oils in the leaves tend to make the fire more severe and therefore more damaging to less attuned species. Epicormic buds under the often thick bark of the trunk and branches are ready to sprout new stems and leaves after a fire.
Family RosaceaeTrue cherry fruits are born by members of the sub-genus Cerasus which is distinguished by having the flowers in small corymbs of several together (not singly, nor in racemes), and by having a smooth fruit with only a weak groove or none along one side. The subgenus is native to the temperate regions of the Northern Hemisphere, with two species in America, three in Europe, and the remainder in Asian continent
Family LamiaceaeTectona grandis is a large, deciduous tree up to 40 m (131 ft) tall with gray to grayish brown branchlets. Leaves are ovate-elliptic to ovate, 15–45 cm (5.9–17.7 in) long by 8–23 cm (3.1–9.1 in) wide, and are held on robust petioles that are 2–4 cm (0.8–1.6 in) long. Leaf margins are entire.
Family MalvaceaeThe Tilia's sturdy trunk stands like a pillar and the branches divide and subdivide into numerous ramifications on which the twigs are fine and thick. In summer these are profusely clothed with large leaves and the result is a dense head of abundant foliage.
