The Poales...

According to the New York Flora Atlas, the New York population of Poaceae (the true gasses) contains 111 genera and 381 taxa.

Subfamily Panicoideae[edit]

The Panicoideae membership used here is based on Zuloaga, Fernando O.; Morrone, Osvaldo; Davidse, Gerrit; and Pennington, Susan J. (2007) "Classification and Biogeography of Panicoideae (Poaceae) in the New World," Aliso: A Journal of Systematic and Evolutionary Botany: Vol. 23: Iss. 1, Article 39.

Panicum sect. Virgata[edit]

The New York population of section Virgata consists primarily of switchgrass (Panicum virgatum) along with some dune panicgrass (Panicum amarum) near the Atlantic coast.

Switchgrass is a warm-season native of eastern and central North America. It is available in many different agricultural, horticultural, and conservation cultivars, not all of which are appropriate for New York State conditions. An example of an appropriate cultivar for conservation purposes in New York is 'Shelter' switchgrass, which is a northeastern ecotype from West Virginia, released in 1978 from the USDA's Big Flats site.[1]

Before European settlement, northeastern switchgrass was restricted to a narrow coastal band. Recent studies have found that adjacent inland switchgrass populations contain a significant majority of individuals from outside the Northeast.[2]

The range of dune panicgrass or bitter panicgrass lies mostly on the Atlantic coast from southern New England to Mexico. It is primarily used for erosion control on coastal dunes. Both the New York native var. amarum and the more southern var. amrulum are planted for erosion control in New York.
