- Restricting this list geographically is in keeping with my specialization in plants native to northeastern North America.
- There are many more tropical plants, and plant extinctions, than I can manage; for example, Cuba alone has lost more plant species than I've listed on this blog post.
If you have additions to this list, please let me know, and provide a link which I can research.

Extinct in the wild (IUCN Red List code EW)
Extinct versus ExtirpatedI often come across misuse of the word "extinct," as in: native plant extinct in New York City.
- "Extinct" means globally extinct. No living specimens exist anywhere in the world, not even in cultivation.
- "Extirpated" means locally extinct, while the species persists in other populations outside of the study area. To correct the above example: extirpated in New York City. Any regional Flora lists many extirpated species.
Another category is "extinct in the wild," when the species still exists under cultivation, like an animal in a zoo. A famous example of this is Franklinia alatamaha.
