Dawn redwood
Metasequoia glyptostroboides
Also known as: Metasequoia glyptostroboides
A deciduous coniferous tree — the only living species in the genus *Metasequoia*, one of three surviving redwoods alongside the [[coast-redwood]] and the [[giant-sequoia]]. Known to science from 100-million-year-old fossils long before any living specimens were identified — the genus was assumed extinct. Then in 1943 a Chinese forester recognized a living tree in central China that matched the fossil descriptions; subsequent expeditions confirmed a small surviving population in Hubei Province. One of the most dramatic 'living fossil' rediscoveries in 20th-century botany.
Scientific
Metasequoia glyptostroboides (family Cupressaceae) is one of only a few deciduous conifers — the species drops its needles each autumn, with a brilliant rust-orange autumn color before drop. The other major deciduous conifers are [[bald-cypress|bald cypress]] ([[bald-cypress|Taxodium distichum]]) and larches (Larix).
The genus Metasequoia was first described by Japanese paleobotanist Shigeru Miki in 1941 — from 100-million-year-old fossils. Miki assumed the genus extinct, like most fossil conifer genera. Two years later, in 1943, Chinese forester Zhan Wang collected specimens from a previously unidentified tree in central China. By 1948 a small surviving wild population had been confirmed in Hubei and Hunan provinces, and seed collections distributed to botanic gardens worldwide.
Cultural and conservation
The dawn-redwood rediscovery is one of the most dramatic “living fossil” stories in modern science — comparable to the 1938 rediscovery of the coelacanth, a fish thought extinct for 65 million years. Within a decade of the 1948 confirmation, dawn redwood saplings (grown from collected seed) were planted at major botanical gardens around the world, including the Arnold Arboretum at Harvard.
The wild population in China is small (~5,000 mature trees) and listed as Endangered on the IUCN Red List. Cultivated populations in arboreta and parks across the temperate world now far exceed the wild population — a curious case where a species’ future likely depends on continued horticultural propagation rather than wild conservation.
The species is one of the fastest-growing redwoods in cultivation, easy to propagate, tolerant of urban conditions, and notable for its autumn color — making it one of the more-planted specimen trees in 21st-century arboreta and park installations.
