The claimed use of Latin ignores Endlicher’s philological background and familiarity with the Latin of the ancient manuscripts in the royal library on which he extensively published. Endlicher could not have known how Sequoyah’s name was pronounced in Cherokee since he never had the opportunity to hear spoken Cherokee. The alleged positive link is based on a similarity in pronunciation of the words “Sequoyah” and “Sequoia” valid to persons that think in English, but not those that think in German or Latin. In 2017, Nancy Muleady-Mecham of Northern Arizona University, after extensive research with original documents in Austria, claimed to find a positive link to the person Sequoyah and Endlicher as well as information that the use of the Latin sequor would not have been correct, however there are debilitating limitations to the arguments presented in the 2017 article. However, in a 2012 article, author Gary Lowe argues that Endlicher would not have had the knowledge to conceive of Sequoia sempervirens as the successor to a fossil sequence, and that he more likely saw it, within the framework of his taxonomic arrangements, as completing a morphological sequence of species in regards to the number of seeds per cone scale. Beginning in the 1860s, it was suggested that the name is instead a derivation from the Latin word for 'sequence', since the species was thought to be a follower or remnant of massive ancient, extinct species, and thus the next in a sequence. The most common modern guess is that Endlicher, a published linguist, sinologist, philologist, as well as a systematic botanist, named the genus in honor of Sequoyah, the inventor of the Cherokee writing system, now known as Sequoyan. However, he left no specific reasons for choosing that name, and there is no record of anyone else speaking to him about its origin.

The name Sequoia was first published as a genus name by the Austrian botanist Stephan Endlicher in 1847. Several extinct species have been named from fossils, including Sequoia affinis(Western North America), Sequoia chinensis (no valid reference, identification uncertain) of China, Sequoia langsdorfii (reclassified as Metasequoia ), Sequoia dakotensis (reclassified as Metasequoia ) of South Dakota ( Maastrichtian), and Sequoia magnifica ( petrified wood from the Yellowstone National Park area). It includes the tallest trees, as well as the heaviest, in the world. The two other genera in the subfamily Sequoioideae, Sequoiadendron and Metasequoia, are closely related to Sequoia. 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. Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. 'Icicle Tree' showing burling of the trunk
