Dawn Redwood
Metasequoia glyptostroboides
Every dawn redwood on this page descends from one valley in central China. We map 17 of them, in 16 cities.
The species was known only from imprints in stone and filed under extinct until living trees were found there in the 1940s, and seed collected in 1947 and 1948 went out by post to botanical gardens around the world, which is where these came from. The rediscovery gets dated to 1941 and to 1944 depending on which step is being counted, and both dates turn up in the records behind these trees. They are young, most between sixty and eighty years old, and worth the walk anyway, because a conifer that turns rust orange and drops its needles every winter is an odd thing to meet. Portland's coned in 1952, the first any dawn redwood had done in the Western Hemisphere since the species vanished from it.
