Metasequoia is a genus of deciduous conifers, commonly known as dawn redwoods. The term "metasequoia" has no true synonyms, as it is a scientific name that has been universally accepted by botanists. However, there are other common names that are used to refer to Metasequoia. These include China redwood, water fir, and dawn redwood tree. These names refer to the origins of the tree from China, the ability to grow in wet conditions, and the tree's deciduous habit, respectively. While not true synonyms, these alternative names still provide a clear and accurate description of the tree species known as Metasequoia.
