Tribe Poeae R.Br. (1814) worldwide contains 2776 species in 118 genera. Soreng et al. (1990) identified two plastid clades: Chloroplast Group 1 (Aveneae type) and Chloroplast Group 2 (Poeae type).^[1]

Torreyochloa

Torreyochloa pauciflora

Torreyochloa (false mannagrass) has also been treated as a section of Puccinellia (alkali grass). Torreyochloa can be distinguished from similar wetland species of Glyceria and Puccinellia by Torreyochloa's open leaf sheaths, 3-veined upper glumes, and conspicuous veins on its lemmas.^[1]

Phalaris

Phalaris arundinacea

Two canary grasses, Phalaris arundinacea (reed canary grass) and Phalaris canariensis (annual canary grass) are common in New York.

The New York Flora Atlas (2021) lists Phalaris arundinacea as native to New York because native genotypes of the grass once occurred in the state. But the Atlas states that the native genotypes are either extirpated or very rare, referring to Jakubowski et al. (2012 & 2014)^[1] and Nelson et al. (2014).^[2]

Although the New York Flora Atlas only lists Phalaris arundinacea var. picta as a synonym of Phalaris arundinacea, the Catalogue of New World Grasses (2003) lists both P. arundinacea var. arundinacea and P. arundinacea var picta as valid taxa.^[3] Because the ornamental var. picta is readily identifiable by its striped leaves, it's doubtful that it has naturalized in New York without being reported. However, it is believed that hardy European races of var. arundinacea have been introduced at various times since early European settlement and have probably hybridized with American races. So, the Phalaris arundinacea species may be considered invasive in New York.^[4]

Subtribe Anthoxanthinae

Subtribe Anthoxanthinae A. Gray (1856) contains only Anthoxanthum.^[1]

Anthoxanthum

Anthoxanthum is known variously as sweetgrass, vernalgrass, vanillagrass, or holygrass. The merging of the genus Hierochloe into Anthoxanthum by Schouten and Veldkamp (1985) may be cause for confusion between the native Anthoxanthum nitens (formerly Hierochloe odorata) and the Eurasian Anthoxanthum odoratum. These are two distinct species, and A. nitens appears never to have been considered a sub-taxon of A. odoratum.

Anthoxanthum subg. Hierochloe

Anthoxanthum nitens

The grasses of Anthoxanthum subg. Hierochloe are generally known as sweetgrass. Because A. hirtum and A. nitens were previously included together under Hierochloe odorata, the county-level distribution shown here for these two species is likely incorrect. The A. hirtum map is based on the BONAP map, while the A. nitens is based on the NYFA map as of 10-Nov-2016.

Anthoxanthum subg. Anthoxanthum

Anthoxanthum odoratum

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.

Calamagrostis

Calamagrostis canadensis
Canada bluejoint grass

Jeffery M. Saarela et al. (2017) showed that two species of Ammophila are nested within separate clades in Calamagrostis s.s., making both Ammophila and Calamagrostis polyphyletic. Merging Ammophila into Calamagrostis was the solution.^[1]

Molecular and morphological studies have shown that native eastern North American beechgrass comprises a number of lineages with overlapping characteristics that may be best treated as a single species:^[2]

Coastal populations (A. breviligulata):
- Northern Atlantic coast,
- Southern Atlantic coast,
Interior populations (A. champlainensis):
- Lake Champlain & St. Lawrence River, and
- Great Lakes.

Phleum pratense

The genus Phleum contains several grasses commonly called timothy. In New York State, it consists almost entirely of common timothy (Phleum pratense), which probably grows in every county and is listed as moderately invasive.

Poa

Poa is the largest genus of grasses and contains over 500 species throughout temperate and boreal regions in both hemispheres. North American Poa species are generally known as bluegrass. The system used here for subgeneric Poa organization is based on Gillespie and Soreng (2005).^[1] The subgenera names use here are those proposed in Gillespie et al. (2007).^[2]

Poa subg. Arctopoa

Poa subg. Arctopoa Grisebach (1971) 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. Subgenus Arctopoa comprises five species in two sections found in seashore and interior wetland habitats of northern, cool temperate regions.

Poa subg. Ochlopoa (Ascherson & Graebner) Hylander (1953) is here treated as equivalent to the BAPO clade, comprising previous subg. Poa sections: ( ( Bolbophorum + Alpinae ) ( Parodiochloa + Ochlopoa ) ).

Poa subg. Ochlopoa sect. Micrantherae

Poa annua

Annual bluegrass (Poa annua) is the only annual species of Poa present outside of cultivation in New York State. It is listed in Randall 2012 as one of the most aggressive weeds invading areas in all continents from sea level up to 4000 ft. in elevation.^[1] It is the only alien plant having a successfully established population in maritime Antarctica.^[2]

[14] When separated into subspecies, A. hirtum ssp. arcticum is the only North American native of the species. The New York Flora Atlas (2016) treats all A. hirtum subspecies as one variable taxon, baed on Allred and Barkworth (2007).
