Banded Trinity (Thismia americana)
Description
Thismia americana, the banded trinity, was a species of flowering plant that was described and published as living in wetlands surrounding Chicago's Lake Calumet in the 1910s. The specimen was found in what was then a wet-mesic sand prairie at 119th Street and Torrence Avenue in what would become the industrial neighborhood of South Deering. The plant has not been seen since 1916, and the ground where it was observed has since been extensively altered by industrial development. The species is believed to be extinct. An extensive volunteer search, conducted in August 2011 on the far south side of Chicago, did not uncover any specimens of the vanished species
