From A World-wide Phylogenetic Classification of Poaceae

Subfamily Pooideae[edit | edit source]

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

Tribe Brachyelytreae[edit | edit source]

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

Brachyelytrum[edit | edit source]

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.

Brachyelytrum aristosum (northern shorthusk): Lemmas (0.7-) 0.8—1.2 (-1.4) mm wide, minutely scabrous, longest hairs (0.06-) 0.08—0.14 (-0.2) mm long, not evident at 10x; weakly veined, mid-veins similar in prominence to secondary veins; widest leaf blades (0.8-) 1.0—1.4 (-1.6) cm wide;
Brachyelytrum erectum (southern shorthusk): Lemmas (0.8-) 1.1—1.5 (-1.8) mm wide, hispid, longest hairs (0.2-) 0.4—0.8 (-0.9) mm long, easily seen under 10x magnification, conspicuously veined, mid-veins more prominent than the secondary veins; widest leaf blades (0.9-) 1.1—1.7 (-2.0) cm wide.^[2]

Nardus[edit | edit source]

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.

Glyceria[edit | edit source]

Glyceria (manna grass or sweet grass) is treated here based on:

Glyceria sect. Hydropoa[edit | edit source]

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.

An observation of Glyceria maxima made by Paul Rutledge in Wyoming County 1994 is shown in iMapInvasives.^[1]

↑ iMapInvasives presence record for Reed Mannagrass in Wyoming County (Carlton Hill Upper Little Tonawanda Creek) made by Paul Rutledge in 1994, based on data mined in 2015.

Brachypodium[edit | edit source]

Brachypodium, commonly known as false brome contains the invasive slender false brome (B. sylvaticum), which has a number of dense populations in New York and according to iMapInvasives is present in at least 11 counties.^[1]

Purple false brome (B. distachyon) has not been reported in New York, but in listed in iMap as Highly invasive with an NYS Tier of 1b, as it is present in New Jersey.

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.

Bromus sect. Genea[edit | edit source]

Bromus sect. Genea Dumort. in New York State consists primarily of the moderately invasive Bromus tectorum (cheat grass, downy brome, or downy chess). Other species of this section also present in the state are Bromus diandrus (ripgut brome), B. rubens (red brome), and B. sterilis (poverty brome). All grasses in this section are native to Europe and northern Africa^[1]

Unpublished. The Nature Conservancy, Albany & Cold Spring Harbor, NY; Brooklyn Botanic Garden, Brooklyn, NY. ↑ The invasive grass Bromus tectorum is troublesome to farmers and many ecosystems. It usually thrives in disturbed areas preventing natives from returning to the area. Disturbance such as overgrazing, cultivation, and frequent fires encourage invasion. Once established the natives cannot compete and the whole ecosystem is altered. Global Invasive Species Database (2021) Species profile: Bromus tectorum.

Agropyron[edit | edit source]

Agropyron cristatum (crested wheatgrass) is common and considered invasive in the west but is uncommon in New York State. The New York Flora Atlas shows that it was collected from five counties during the 1940s and '50s. It also infers that North American Agropyron cristatum has likely introgressed with Agropyron desertorum (desert wheatgrass) to a degree that makes them indistinguishable.
