First published 13 Jan. 2000 as Classification of New World Grasses (Poaceae/Gramineae). Data are under continuous revision after this time. This page last revised 30 June 2017 (previous significant revisions/updates, 11 Dec 2013, 13 Dec 2011, Apr 2012, 8 Aug 2012, 18 Oct 2012, 5 Apr 2014, 3 Apr 2015, 23 Mar 2015, 2 Jun 2017).


The following classification was initiated for the Catalogue of New World Grasses project. It now includes subfamilies (12), supertribes (7), tribes (52), supersubtribes (5), subtribes (94), and accepted genera for the World (768). Synonyms of suprageneric taxa, and synonyms of genera that are frequently recognized as distinct, are also cited. Strictly Old World suprageneric taxa were added to the classification arrangement in 2011 for all subfamilies.

Our classification builds on those of Clayton & Renvoize (1986), Tzvelev (1976, 1989), Watson & Dallwitz (1992), Grass Phylogeny Working Group (2001), for Bambuseae and allies, Soderstrom & Ellis (1987 [1988]), and for New World Poaceae, the four volumes of the Catalogue of New World Grasses (2000-2003, Contr. U. S. Natl. Herb. vols. 39, 41, 46 & 48), all those that have gone before, and many newer works including, for Paniceae and Paspaleae (Morrone et al. 2012), Andropogoneae (Estep et al., 2014), Arundinoideae (Teisher 2017), Bambusoideae (BPG: Bamboo Phylogeny Group 2012, Kelchner & BPG 2013, Wong et al. 2016, Vorontsova et al. 2017), Chloridoideae (Peterson et al. 2010, 2011, 2012, 2013, 2014, 2015, 2016), Danthonioideae (Linder et al. 2010), Pooideae (Hochbach et al. 2015), Poeae (Barbera et al. in prep, Gillespie et al. 2010, Refulio Rodrguez et al. 2012, Saarela et al. 2010, 2017, Soreng et al. 2015b, Wlk et al. 2015, Wlk & Rser 2014, 2017), Stipeae (Romaschenko et al. 2008, 2010, 2011, 2012, 2013).

Our previous classification was published by Soreng et al., 2105 (on-line 23 March 2015), in the Journal of Systemtics and Evoulution: <http://dx.doi.org/doi:10.1111/jse.12150>. Kellogg (2015) produced a similar classification of the family in vol. 8 of Kubitzkis series The Families and Genera of Vascular Plants. Our classification is revised here, for publication JSE in July of 2017 (Soreng et al. 2017), along with 4 newer subtribes in Chloridoideae (Peterson et al., 2017).

Much of our revision results from many DNA phylogenetic studies over the last 27 years. For bibliographic references see <http://www.tropicos.org/ReferenceSearch.aspx>Advanced Search Key Words: Poaceae, DNA.

For a continually updated listing of accepted genera and recorded synonyms and their authorships see < http://www.tropicos.org/Reference/100019731>. All suprageneric taxa and genera are recorded in Tropicos with their authorships, original place of publication and types, along with historical usage: <http://www.tropicos.org/Home.aspx>.  Lists of suprageneric taxa (and others) can be generated in Tropicos using the Advanced Search options under: <http://www.tropicos.org/NameSearch.aspx>. A number of older legitimate citations of place and author, and newly recognized groups, and invalid, illegitimate, and unranked names, have been detected since the publication of Genera Graminum (Clayton & Renvoize, 1986). Much work has been done in evaluating the pre-1900 suprageneric nomenclature literature, especially by Jim Reveal (recently, several tribe names were upset by the rediscovery of tribe names by Martinov, 1820, but further evaluation of the original text revealed these were mostly invalid (Welker et al. 2014). The rank of Horaninow (1947) suprageneric names remains unsetteled. For suprageneric taxa accepted as legitimate by Jim Reveal see: <http://www.plantsystematics.org/reveal/pbio/WWW/supragen.html>.

The starting date of the rule that rank terminations themselves (if consistent with oideae, eae and inae ranking for subfamily, tribe and subtribe) determine rank, even if rank was not explicitly stated at the time of publication, extends back to 1887 (previously, the cutoff was 1 Jan 1908; Art. 37.2 Melbourne Code). We have not had time to evaluate the impact of this change for Poaceae. Two other suprageneric ranks sporadically applied here, supertribe and supersubtribe, end in odae and odinae, respectively. Also, authorship of names of suprageneric taxa transferred from one rank to another no longer include the original authors (parenthetically) (Art. 49.2), even if the transfer would be invalid without the citation of the basionym or replaced synonym (Art. 41.20). In the latter case we consider such changes of rank as replacement names (nom. novs.), otherwise the place of validation gets lost. This is not done if a suprageneric name is validly published for the first time.

Accepted suprageneric names appear in bold type. The indigenous range of each genus is colored as follows: Western Hemisphere, Eurasia (including genera that in Africa are exclusively Mediterranean, but not exclusively African), Australasia, Africa. Genera with bimodal distributions are bicolored, those with broader distributions tricolored, or are red if more widely distributed. Genera in synonymy (syn. ..) are colored if the accepted genus is more widely distributed, i.e., in more than one area. Genera in italics have been sampled in DNA studies. Comments and C3 and C4 photosynthetic pathways are in brackets { }. Publication dates for suprageneric taxa appear in square brackets [ ].
