Observations

Remarks

The genus began with the ca. 1838 discovery, by pioneering Southeastern botanist Harvey Croom, of Torreya taxifolia; the genus was named for John Torrey (1796-1873), one of the most celebrated U.S. botanists of the mid-19th century (Eifert 1965). Torrey himself was later (1854) to describe another species in the genus, Torreya californica.
