Synonymy for the
Manual of North American Grasses North of Mexico and
Flora North America, vols. 24 & 25
The nomenclatural treatment that was developed in connection with the Manual of North American Grasses is so extensive that it will be published as a separate volume late in 2003 and included in the Manual (= FNA vol. 24) on a compact disk.  The abbreviations used for authors' names are those recommended by Brummit and Powell (1992). Journal abbreviations are from Botanico Periodicum Huntianum/Supplementum (Bridson and Smith 1991); book abbreviations are from the many volumes of Taxonomic Literature, edition 2 (Stafleu and Cowan 1976-1988; Stafleu and Mennega 1992+), all of which are part of Regnum Vegetabile series. Herbarium codes are taken from Index Herbariorum (Holmgren et al. 1990), another publication in the Regnum Vegetabile series.

Much of the nomenclatural information has been compiled from secondary sources. Contributors were asked to notify us if they had, themselves, examined the holotype, lectotype, or neotype of a name.  If they had done so, an exclamation point (!) occurs after the information about where the specimen is located.

The location of holotypes, lectotypes, and neotypes is given when we were able to obtain it. We have not recorded the location of isotypes, partly because there are so many for some names and we did not wish to decide which to cite, partly because, in the event of a dispute over the meaning of a name, they cannot provide a definitive answer.

And one day we shall post pages providing an explanation of the terms that are used in the nomenclatural treatments.

For a list of all the scientific names of the subfamilies, tribes, and taxa that are described in volume 25 of the Flora of North America series, plus those that will be treated in volume 24, click here. Some of these species are known only in cultivation; the listing also shows some synonyms of the taxa mentioned in these volumes.
