From A World-wide Phylogenetic Classification of Poaceae

Subfamily PooideaeEdit

Subfam. Pooideae Benth. (1861) is a large group that contains the cool-season grasses. This includes barley, oats, rye, wheat, and others.

Tribe BrachyelytreaeEdit

Tribe Brachyelytreae Ohwi (1941) contains only the genus Brachyelytrum.[1]

BrachyelytrumEdit

The ranges of the two North American shorthusk species overlap in New York, and they grow closely together in some parts of the state, but not in mixed populations, nor have they been known to hybridize.[1]

According to the New York Flora Atlas, both shorthusk species grow in mesic hardwood forests. Northern shorthusk (B. aristosum) is found in cooler, more northern sites, while southern shorthusk (B. erectum) usually grows in warmer, more southern sites, and sometimes in dry-mesic or calcareous sites.

Tribe NardeaeEdit

Tribe Nardeae W.D.J. Koch. (1837) contains only the genus Nardus..[1]

NardusEdit

 
Nardus stricta
Nardus stricta (matgrass) is and Old-World grass that has been found in northern New York, New England, and eastern Canada. It is also present in Oregon and Idaho, where it is listed as a noxious weed.

Tribe MeliceaeEdit

Tribe Meliceae Link ex Endl. (1830) contains Glyceria, Lycochloa, Melica, Pleuropogon, Schizachne, and Triniochloa.[1]

GlyceriaEdit

Glyceria (manna grass) is treated here based on:

Glyceria sect. HydropoaEdit
Glyceria sect. Hydropoa (Dumort.) Dumort includes a total of about five species, of which only American manna grass in known to grow in New York State. The Eurasian G. maxima is assessed as highly invasive for the region, but there have as yet been no vouchered reports in New York. However, there is concern that some of the specimens of G. grandis might in fact be G. maxima.

OryzopsisEdit

 
Oryzopsis asperifolia
The name Oryzopsis reflects a similarity to the genus Oryza (rice). Spreading whitegrass, roughleaf ricegrass, or white-grained mountain rice grass is common in shaded habitats of New York.

Tribe BrachypodieaeEdit

Tribe Brachypodieae Harz (1880) consists of the single genus Brachypodium (syn. Trachynia),[1] which has no known species that are native to the western hemisphere.

BrachypodiumEdit

 
Brachypodium sylvaticum
slender false brome
Brachypodium, commonly known as false brome contains the invasive slender false brome (B. sylvaticum), which has a few dense populations in New York. Heath false brome (B. pinnatum) has not been reported in New York, but may be of concern because it has been reported in western Massachusetts.
