The Journal of the Torrey Botanical Society (until 1997 the Bulletin of the Torrey Botanical Club), the oldest botanical journal in the Americas, has as its primary goal the dissemination of scientific knowledge about plants (including thallopyhtes and fungi). It publishes basic research in all areas of plant biology, except horticulture, with an emphasis on research done in, and about plants of, the Western Hemisphere.
The Memoirs of the Torrey Botanical Society are published at irregular intervals in volumes of various sizes when a feature subject or a special collation of topics arises. The peer-reviewed Memoirs comprise a series of longer botanical papers (over 50 printed pages long) and monographs that began in 1889; to date, 67 issues have been published in 26 volumes. Early issues of the Memoirs often were dedicated to taxonomic monographs and revisions by a single author, but more recent issues usually have presented discussions of topics by a collaboration of authors. The most current volume 26 is the first to be published in association with another botanical society.
