Genus: SequoiaView Description 


Common Name: REDWOOD

Species In Genus: 1 sp.: western North America. Etymology: (John Lockhart has indicated (7 Jul 2004 Interchange Feedback) that, according to Asa Gray, no one has ever found, in the writings of Endlicher (author of the genus name Sequoia), any mention of Sequoyah, the Cherokee chief for whom the genus Sequoia is often said to have been named (in Cherokee, "sequoyah" means "opossum"), and that Gray instead believed that the stem of the word was a derivation from the Latin "sequi" or "sequor," meaning "sequence" or "following," in reference to the fact that redwoods were remnants or followers of numerous fossil ancestors.)

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
