From A World-wide Phylogenetic Classification of Poaceae

Subfamily Pooideae[edit]

The Pooideae is a large subfamily that contains the cool-season grasses. This includes barley, oats, rye, wheat, and others.

Tribe Brachyelytreae[edit]

Genus Brachyelytrum[edit]

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]

Tribe Nardeae[edit]

Genus Nardus[edit]

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.

Genus Glyceria[edit]

Glyceria (manna grass) is treated here based on:

Glyceria sect. Hydropoa[edit]

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.

Tribe Brachypodieae[edit]

The Brachypodieae consists of the single genus Brachypodium, which has no known species that are native to the western hemisphere.

Genus Brachypodium[edit]

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.
