Torrey Botanical Society

Torrey Botanical Society (formerly Torrey Botanical Club) was started in the 1860s by colleagues of John Torrey. It is the oldest botanical society in the Americas. The Society promotes the exploration and study of plant life, with particular focus on the flora of the regions surrounding New York City. Members of the group including Nathaniel Lord Britton and his wife Elizabeth Gertrude Britton founded the New York Botanical Garden. Provided by Wikipedia
