Brachyelytrum

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]

Glyceria sect. Hydropoa

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.

Brachypodium

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.
