The legacy of John Torrey (1796-1873) has many dimensions, all of which revolve around his unsurpassed prominence as a scholar of North American botany during most of the 19th century. This historical volume of the Memoirs of the Torrey Botanical Society is occasioned by the 2017 celebration by the Torrey Botanical Society of the 150th anniversary of the club’s formation in New York City in 1867.

This volume contains 10 original articles reviewing the multiple legacies of John Torrey as well as the proceedings and abstracts of the lectures presented at the Torrey Society’s 150th Anniversary Symposium held in September 2017.
