What is the tallest tree in the world?

Answer 1

The name of the tree is Hyperion. It is a 379.1 foot redwood in Redwood National Park in California. It was found to be the tallest in September of 2006, displacing Stratosphere Giant (also a redwood from the same area) to become the tallest living tree in the world.

Answer 2

Although redwoods (sequoias) are usually thought to be the tallest trees, one has to mention the lianas. These are tropical vine-like trees that twist around other trees and thus do not look that tall However they get to be 330 ft (100 m) high. Also one has to consider the root system (after all it is part of the tree) and many trees have very extensive root systems.
Below is records for individual trees.

Martin, Alexander and Zim, Herbert. "Redwood and Giant Sequoia." Trees. New York: Golden Press, 1987: 34. "Redwood, with leaves suggesting Hemlock, is the tallest tree (record: 364 ft)." 110.9 m
"Redwoods in the National Mist." National Wildlife. Vol. 37, No. 3, Apr/May 99: 10. "The finding may explain why redwoods are the tallest trees on Earth. The biggest living redwood is 370 feet tall." 112.8 m
Tallest Living Tree. Guinness World Records. "The tallest living tree today is the Mendocino Tree, a coast redwood (Sequoia sempervirens) found at Montgomery State Reserve near Ukiah, California, USA. In September 1998, it was 112 m (367.5 ft) tall, with a diameter of 3.14 m (10 ft)." 112 m
"A Eucalyptus regnans at Mt. Baw Baw, Victoria, Australian, is believed to have measured 143 m (470 ft.)1885. Formerly, another Australian eucalyptus, at Watts River, Victoria. almost certainly had been over 150 m (492 ft.) tall." 150 m
