The Recently Extinct Plants Database

I have written a free eBook, 'What's Lost and What Remains: The Sixth Extinction in 100 Accounts'.

Please use the Contact form to report any hyperlinks that no longer work ("deadlinks"). The internet is a dynamic place, and websites come and go all the time. As a single individual I cannot constantly check to make sure every single hyperlink still works, as there are literally 10,000's of them on the website.

NB: The classification of plants and their allies presented here is a simplified version intended for the general reader. It should not be interpreted as an authoritative taxonomic treatment.

NB: POWO (Plants of the World Online) uses "Extinct" (with red geographical distribution instead of green) for both globally extinct and extinct in the wild taxa, so distinguishing between these two conservation categories where POWO does not explicitly state which applies (under 'General Information') is based upon a broader understanding of the literature. In some cases this may be wrong, as I do not have access to all of the literature that they reference. For taxa that I cannot find any evidence for their ever being in cultivation/ex situ I cite POWO as considering those taxa globally extinct by default.

1 Taxonomic ranks encompassed by square brackets (i.e. "[" and "]") have no relevant subordinate taxa. That is, none of the species or subspecies included therein both a) survived at least until the late Pleistocene and b) are considered missing, extinct, rediscovered, or have been removed from these former categories due to taxonomic invalidity. This juxtaposition of non-empty and empty taxonomic units helps to identify potential instances of taxonomic bias in recent extinctions, and by extension those groups of organisms that may have an innate buffer against extinction.
