There are eight different types of sequoia trees that fall into four families, two of those families being coniferous and two that are deciduous. The first family of sequoias we will deal with is the largest family, the Cupressaceae family. The Cupressaceae family is populated by conifers and is made up of four distinct trees. Le Sequoia sempervirens, also known as the “Redwood Coast;” the glyptostroboides Metasequoia or “Dawn Redwood;” and the Cryptomeria japonica, which is more commonly called “Sugi” are all the sequoia trees in the conifers Family Cupressaceae. There is a fourth tree in this family. The fourth tree is the Sequoiadendron giganteum,which goes under two different names. It is called both “Giant Sequoia” and “Sierra Redwood.”
The second family of redwood conifers is the Pinaceae family. This family includes only one sequoia, Pinus sylvestris. Pinus sylvestris is called the “Scots pine.” In the wood sector, this tree is simply referred to as “Redwood”.
Now we come to the two family of deciduous hardwoods, none of which are as large as the Cupressaceae family. The Fabaceae family includes only two sequoias. The Sterculiaceae family, like the Pinaceae coniferous family, includes only one sequoia. Within the Fabaceae family are the sappan Caesalpinia, which is also known as the “East Indian Redwood” or “Sapanwood tree,” and the Caesalpinia echinata, which is known as both the “American South Redwood” and “Brazilwood tree.” In Europe, sappa Caesalpinia is also sometimes referred to as “Brezel wood”. The second broadlead family of trees, of the Sterculiaceae family, includes the Erythroxylon Trochetiopsis, which is more commonly known as the S. Elena Redwood.
As you can guess from the names, redwoods are found in many places around the world. The Brazilwood tree, for example, is originally from Brazil. Giant Sequoia, for another example, mainly grows in California. It is also known as “Sierra Redwood” because it grows mainly in the western Sierra Nevada mountain range within the state of California. Since the tree is considered endangered, it has been grown in Europe, Canada, Australia and New Zealand.
The Sugi tree, however, originates from Japan. Although not a member of the cedar family, Sugi is sometimes called “Japanese Cedar.” Scots pine can be found in many places around the world, including Ireland, Great Britain, Siberia, and Portugal.
