Are the Genii Sequoia and Alpinia native to America ?
Sequoia (genus) Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is "Sequoia sempervirens" in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. The two other genera, "Sequoiadendron" and "Metasequoia", in the subfamily Sequoioideae are closely related to "Sequoia". It includes the largest trees in the world.
List of largest giant sequoias The giant sequoia ("Sequoiadendron giganteum") is the world's most massive tree, and arguably the largest living organism on Earth. It is neither the tallest extant species of tree (that distinction belongs to the coast redwood), nor is it the widest (that distinction belongs to the baobab tree or Montezuma Cypresses), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine). However, with a height of 286 ft or more, a circumference of 113 ft or more, an estimated bole volume of up to 52500 ft3 , and an estimated life span of 1800–2700 years, the giant sequoia is among the tallest, widest and longest-lived of all organisms on Earth.
