Amazing,,, this is the largest and tallest trees in the world ..
Australian Mountain-ash
Eucalyptus regnans (Mountain Ash) is a species of eucalypt native to southeastern Australia. Reaching heights in excess of 90 m, it is recognised as the tallest of all flowering plants.
In physical appearance, a mature forest of mountain ash is an imposing sight, with giant straight trunks, creamy-white to pale green or grey, rising 30–60 m above a wet sclerophyll or rainforest understorey. The tree has a 5–10 m stocking of fibrous brown bark at its often buttressed base; then the smooth cream to light grey gum-type bark above extends to the upper branches. Sometimes the first branches will not appear for 60 m up the trunk, and they are often draped with long peeled strips of annually shed bark. Because the leaves hang vertically, the tree crown may appear unduly small in proportion to the size of the trunk, especially to a viewer directly below the crown.
Lincoln Tree
The location of this tree in the forest of Giant Forest in America. It has the tallest tree height reached 80.0 meters and the volume of 1.259 m3. Tree age is approximately 2500-3000 years.
General Grant Tree
The General Grant tree at Kings Canyon is the third largest sequoia tree in the world and is estimated to be more than 3,000 years old. Located in Grant Grove, the General Grant tree was nicknamed the Nation's Christmas Tree by President Calvin Coolidge, and remains one of the most popular attractions in Kings Canyon National Park. Annual Christmas services are held at the base of General Grant, which provide visitors and park staff with fantastic photo opportunities and the chance to enjoy the majestic tree dressed up for the season.
Coast Redwood
In the most favorable parts of their range, California’s magnificent coast redwoods can grow more than 320 feet high (about as tall as a 30-story building), with trunks more than 24 feet in diameter at breast-height, and can live for more than 2,000 years. However, ancient coast redwoods are rare — less than 5 percent of the original forest remains today. These ancient forests contain the highest standing biomass (total of all aboveground organic matter) of any forest on Earth and, therefore, store incredible amounts of carbon.
General Sherman Tree
The General Sherman Tree is located in Sequoia National Park, California. The General Sherman trailhead is just off of Generals Highway at Wolverton Road, and the ½-mile trail is paved.
Multiple other trails also lead to the General Sherman Tree and handicap accessible parking is located directly off Generals Highway. The General Sherman trail itself descends 200 feet, less than the height of the tree.
Coast Douglas Fir
Douglas-fir is the common named applied to coniferous trees of the Genus Pseudotsuga in the Family Pinaceae, with two species native to the Pacific coast and mountains of western North America, one in Mexico and two in eastern Asia. The Douglas-firs have given botanists fits due to their similarity to various other conifers: having, at times, been called pines, spruces, hemlocks, and true firs. Because of the distinctive cones, Douglas-firs were, in 1867, placed in the new genus Pseudotsuga, meaning "false hemlock". The hyphen in the common name indicates that Douglas-fir is not a "true" fir — it is not a member of the genus Abies. The common name honors David Douglas, the Scottish botanist who first introduced the tree into cultivation in 1826. Douglas is known for introducing many North American native conifers to Europe.
The leaves are flat, generally resembling those of the fir. The female cones are pendulous, with (unlike true firs) persistent scales, and are distinct in having long tridentine bracts that protrude prominently above each scale.
The best-known species in the genus is Pseudotsuga menziesii, also known as 'Coast Douglas-fir', 'Oregon Pine', 'Oregon Douglas-fir', 'Douglas Tree', or 'Interior Douglas-fir'. These trees can attain heights second only to the Coast redwood. This species is the state tree of Oregon. The specific name, menziesii, is after Archibald Menzies, a Scottish physician and naturalist who first discovered the tree on Vancouver Island in 1791.
Sitka Spruce
The cones on the Sitka Spruce along the coastal shores of Prince William Sound near Cordova, Alaska start to appear in June after the climate becomes warmer.
The cones hang down off the branches of the Sitka Spruce tree in their cylindrical shape growing to be between five and eleven centimeters long.
