listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
The specific epithet straminea means straw colored (Fernald 1970). It is unclear why this epithet was applied to this species.

State Ranking Justification [-]
There are five known populations and possibly up to 50 historical locations; however, there has been much taxonomic confusion with this plant and all voucher specimens should be verified. Of the known populations, only one has more than a hundred plants and three are of questionable viability. As a species of freshwater marshes, this is threatened by Phragmites, purple loosestrife, and other invasive species.
