Subtribe Uniolinae[edit]

Uniola[edit]

Sea oats (Uniola paniculata) are native to the southeastern coastal United States, Mexico, Bahamas and Cuba. They are not known to have naturalized any farther north than Delaware. Sea oats produce few seeds and spread primarily by rhizomes. This plant is no longer considered to be a close relative of Chasmanthium latifolium (Indian woodoats) which was once placed in this genus as Uniola latifolia and is sometimes known as "northern sea oats".

Subtribe Sporobolinae[edit]

Sporobolus[edit]

The subgeneric classification used here for Sporobolus (Dropseed) is from Peterson et. al. (2014), which includes the genera Calamovilfa, Crypsis, Spartina, and Thellungia (most of Sporobolinae) within Sporobolus to make it monophyletic.[1]

Sporobolus sect. Calamovilfa[edit]

Because the genus Calamovilfa (sandreed) has been found to be embedded within a paraphyletic Sporobolus genus, Peterson et. al. (2014) recommended the transfer of the Calamovilfa species to a subsection within Sporobolus.[1]

Subtribe Boutelouinae[edit]

Bouteloua[edit]

Bouteloua has about 20 species that are native to North America. The two that have been found in New York, sideoats grama and blue grama were both major components of the shortgrass prairie of the Great Plains.[1] Sideoats grama is still common in the west, but has become rare in the east and in listed as endangered in New York. Blue grama is not considered to be native to the Northeast, and is a rare introduction to New York.

Subfamily Arundinoideae[edit]

Phragmites[edit]

The vast majority of Phragmites (common reed) in New York today is of the introduced Eurasian lineage (haplotype M) Phragmites australis subsp. australis. The native lineage (haplotype E) P. australis subsp. americanus is only known to be present in the vicinity of Montezuma Swamp in Cayuga County, although it is likely to have been present, and may still be present elsewhere in the state.

Although the native and non-native Phragmites strains normally share habitats (until the natives are replaced by the non-natives), hybrids of the two were not discovered in the field until 2014, when a hybrid clone was discovered at the Montezuma site.[1]

Subfamily Bambusoideae[edit]

The bamboo subfamily, Bambusoideae Luerss. (1893). Synonyms: Olyroideae Pilg. (1956), Parianoideae Butzin (1965).

Tribe Arundinarieae[edit]

The Arundinarieae contains about 500 temperate woody bamboo species. Most are native to Asia, with only three native to the Western Hemisphere. However, all bamboo species that are known to have naturalized in New York are considered to be invasive or potentially invasive.

Arundinaria[edit]

The three North American bamboo or cane species comprise the genus Arundinaria and are from the southeastern United States.[1] [2] Although listed in New York's Non-Native Plant Species Invasiveness Assessment,[3] both of these species have been excluded from the New York Flora Atlas.
