Barton's proposed flora was never written, but Pursh, who then moved to London, England, did make a major contribution to North American botany in his Flora americae septentrionalis, published in 1813. He then returned to America, moving to Canada in 1816. His hopes of carrying out further major work were prevented by ill health due to alcoholism, and he died destitute in Montreal.
His name is commemorated in the genus Purshia (Bitterbush) and in several species, e.g. Rhamnus purshiana.
