Grass Manual: Synonymy

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 later as a separate volume and included in the Manual (= FNA vol. 24) on a compact disk. The abbreviations used for authors' names are those recommended by Brummitt and Powell. Journal abbreviations are from Botanico Periodicum Huntianum/ Supplementum. Book abbreviations are from the many volumes of Taxonomic Literature, ed. 2, all of which are part of the Regnum Vegetabile series. Herbarium codes are taken from Index Herbariorum, 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 have done so, an exclamation point (!) occurs after the information about where the specimen is located.

The location of holotypes, lectotypes, neotypes, and epitypes 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 ones to cite, and partly because, in the event of a dispute over the meaning of a name, they cannot provide a definitive answer.

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, but only those names included in current floras, herbarium databases, and miscellaneous other publications which were used in creating the maps for volumes 24 and 25. Accepted names are in boldface.
