An authigenically cemented flora from the overburden of the Herrin (No. 6) Coal at Carterville, Illinois has yielded a diverse plant assemblage. Twenty-seven genera and fifty-five species are recognized, of which four taxa are described as new. The dominant component is pteridophyte foliage of Pecopteris Brongniart. The floral assemblage is representative of the Middle Pennsylvanian of North America due to an abundance of Upper Allegheny forms, and representative of the Lower Conemaugh (Stephanian). The flora is equated to Zone 10 of Read and Mamay, and the Westphalian D of Europe.
