The Poaceae tribe Poeae


== Subtribe Torreyochloinae ==


=== Torreyochloa ===
Torreyochloa (false mannagrass) has been treated as a section of Puccinellia (alkali grass).


== Subtribe Aveninae ==
Aveninae J.Presl in C.Presl, Reliq. Haenk. 1:246. Jan–Jun 1830


=== Sphenopholis ===


=== Trisetum ===


=== Graphephorum ===


=== Koeleria ===


=== Arrhenatherum ===


=== Avena ===


=== Rostraria ===


== Subtribe Phalaridinae ==


=== Anthoxanthum ===


==== Anthoxanthum subg. Hierochloe ====


==== Anthoxanthum subg. Anthoxanthum ====
The Old-World Anthoxanthum species found in New York often go by the name vernal grass and appear to be more widespread in the state than the native sweetgrass.


=== Phalaris ===


== Subtribe Brizinae ==


=== Briza ===


== Subtribe Agrostidinae ==


=== Agrostis ===


=== Ammophila ===


=== Calamagrostis ===


=== Polypogon ===


== Subtribe Coleanthinae ==


=== Puccinellia ===
The Puccinellia (alkali grass) species are similar in appearance to the wetland genera Glyceria and Torreyochloa, however, alkali grass is adaptable to saline areas.


=== Sclerochloa ===


== Subtribe Airinae ==


=== Avenella ===


=== Deschampsia ===


=== Vahlodea ===


=== Aira ===


=== Corynephorus ===


=== Holcus ===
The genus Holcus (velvet grass or soft grass)


== Subtribe Cynosurinae ==


=== Cynosurus ===


== Subtribe Dactylidinae ==


=== Dactylis ===


== Subtribe Loliinae ==


=== Festuca ===


=== Vulpia ===


=== Lolium ===


=== Schedonorus ===
Because the Festuca subgenus Schedonorus seems to be more similar to Lolium than to the rest of Festuca, some sources now treat it as its own genus while others now treat it as a subgenus of Lolium.


== Subtribe Parapholiinae ==


=== Catapodium ===


== Subtribe Sesleriinae ==


=== Mibora ===


== Subtribe Alopecurinae ==


=== Alopecurus ===


=== Beckmannia ===


=== Phleum ===


== Subtribe Miliinae ==


=== Milium ===


== Subtribe Poinae ==


=== Poa ===
The system used here for Poa (bluegrass) organization is based on Lynn J. Gillespie and Robert J. Soreng (2005) "A Phylogenetic Analysis of the Bluegrass Genus Poa Based on cpDNA restriction site data." Systematic Botany Vol. 30, No. 1 (Jan. - Mar., 2005), pp. 84–105 Published by: American Society of Plant Taxonomists.
The subgenera names use here are those proposed in: Gillespie, Lynn J.; Archambault, Annie; and Soreng, Robert J. (2007) "Phylogeny of Poa (Poaceae) Based on trnT–trnF Sequence Data: Major Clades and Basal Relationships," Aliso: A Journal of Systematic and Evolutionary Botany: Vol. 23: Iss. 1, Article 33.


==== Poa subg. Arctopoa ====
Poa subg. Arctopoa (Grisebach) Probatova, Novosti Sist. Vyssh. Rast. 8: 34. 1971.
Subg. Arctopoa is here considered equivalent of the ArcSyl clade, made up of subg. Arctopa sections Arctopa and Aphydris, and previous subg. Poa sect. Sylvestris: ( Arctopoa + Sylvestres ).  It is considered to be the basal clade of the genus Poa.


==== Poa subg. Ochlopoa ====
Poa subg. Ochlopoa (Ascherson & Graebner) Hylander, Bot. Not. 1953: 354. 1953.
This subgenus is here treated as equivalent to the BAPO clade, comprising pervious subg. Poa sections: ( ( Bolbophorum + Alpinae ) ( Parodiochloa + Ochlopoa ) ).


==== Poa subg. Stenopoa ====


===== Poa subg. Stenopoa sect. Stenopoa =====


===== Poa subg. Stenopoa sect. Oreinos =====


===== Poa subg. Stenopoa sect. Pandemos =====


===== Poa subg. Stenopoa sect. Tichopoa =====


==== Poa subg. Poa ====
The Poa subgenus is here considered to be composed of the HAMBADD clade (supersect. Homalopoa) and the PoM clade (supersect. Poa).


=== Cinna ===
According to Soreng et. al. (2014) Cinna should be included in Poinae.


=== Apera ===


=== Ventenata ===
