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 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.
