Description
Species of Pine
Hemlocks
Hemlocks are a small group of coniferous trees that are both elegant and useful. These trees have a conical or irregular crown with a graceful drooping habit, making them attractive options to plant in backyards and gardens. The wood is used as wood pulp, which is necessary to make paper and cardboard products. The bark is used in tanning leather.
Pseudolarix
Pseudolarix is a monotypic genus of coniferous trees in the pine family Pinaceae. It has a sole species. It is native to eastern China, occurring in small areas in the mountains of southern Anhui, Zhejiang, Fujian, Jiangxi, Hunan, Hubei and eastern Sichuan. It is a deciduous coniferous tree reaching 30 to 40 m tall, with a broad conic crown. The leaves are bright green, with two glaucous stomatal bands on the underside. The cones are distinctive, superficially resembling a small globe artichoke, with pointed triangular scales; they mature about 7 months after pollination, when (like fir and cedar cones) they disintegrate to release the winged seeds.
Spruces
Spruces are a group of coniferous trees that are of great value to humans in many ways. The wood is used in everything from housing and frame construction to papermaking and crafting musical instruments. Most species grow in handsome, conical shapes, making them popular ornamentals. Many boreal and temperate high-altitude forests around the world are also comprised largely of spruces, making them tremendously ecologically important.
Larches
Larches shed their leaves annually in the fall, and their needles turn a golden yellow when this happens. Larches have coarse-grained and heavy wood, so it is popular in the shipping and construction industries; it has been used for telephone poles, timber, and railroad ties, among other creations.
Firs
A group of evergreen trees, firs are tall conifers that can grow as high as 76 m. They are easily recognized by the unusual way their slender, needle-sized leaves attach to each stem via a basal structure that looks like a small suction cup. The cones of firs are different than pine cones, as they stand erect rather than drooping and tend to be more slender than those of true pine trees.
Cathaya
Cathaya are tall-growing coniferous trees that are native only to China. Their common trait is that each tree produces both male and female cones. The small distribution of these plants and the fact that their wood is useful for different purposes has led some of the species to be classed as vulnerable.
Nothotsuga
Nothotsuga contains only one species, nothotsuga is an evergreen tree reaching 30 m tall. The leaves are flat, needle-like, 1.3 to 4 cm long and 1.02 to 2 mm broad, very similar to those of Tsuga. The cones are very similar to those of Keteleeria, but smaller, 2.5 to 5 cm long, erect, and mature in about 6–8 months after pollination. Nothotsuga contains only one species, which is found in southeastern China, in southern Fujian, northern Guangdong, northeast Guangxi, northeast Guizhou, and southwest Hunan.
Douglas firs
Douglas firs are a group of coniferous trees that are both majestic and useful to humans. Many species grow to enormous sizes and are of great importance to the timber industry. The wood is used for all sorts of construction purposes, while immature trees of this genus are popular as Christmas trees. The U.S. state of Oregon has a douglas firs on the state flag.
Keteleeria
Keteleeria are evergreen trees reaching 35 m tall. The leaves are flat, needle-like. The cones are erect. The genus is found in Asia.
Pines
Pinus (the scientific name for true pines) is a well-known conifer genus whose wood is used extensively in the construction of homes, furniture, buildings, and other structures. Its commercial value exceeds many other types of timber. Turpentine and pine resin derived from pines are also valuable resources that are used throughout the construction and industrial fields.
Cedars
Cedars are a small but widely cultivated group of coniferous trees. Sporting beautiful foliage and bark, many species have been used as ornamentals in warm-temperate parks and gardens worldwide for centuries. Not only does the wood tend to boast both rich color and beautiful grain, but it also has bug-repellent properties. These traits have made the wood useful and valuable for millennia. For example, chests made from cedars have been used to store woolen goods since ancient times since the wood repels moths that feed on wool.
