List of critically endangered plants

Short description: none

Template:IUCN plant chart

Critically Endangered (CR) species face an extremely high risk of extinction in the wild.

As of December 2023, the International Union for Conservation of Nature (IUCN) lists 5702 plant species categorized as Critically Endangered, including 569 which are tagged as possibly extinct and 48 possibly extinct in the wild.[1][2] 8.6% of all evaluated plant species are listed as critically endangered. The IUCN also lists 284 subspecies and varieties as critically endangered.

Additionally 5371 plant species (8.1% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[3] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."[4]

This is a complete list of critically endangered plant species, subspecies and varieties evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such.
