Cheatum’s Wahoo (Euonymus atropurpureus var. cheatumii)
Cheatum’s Wahoo, a variety of the American Wahoo (Euonymus atropurpureus Jacq.), is known only from a single population that was restricted again to a single place in Dallas County, Texas, USA.
This single population is believed to have been destroyed by insects (which insects?) in 1944, the variety is now regarded as being extinct.
