State Protection: Endangered
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: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
The name for the genus comes from the Greek words meaning two-flowering, and refers to the two flowering periods of these grasses, once on the primary stalk in the spring and again on the branches in late summer. This species was named for its discoverer, 19th century botanist Charles Wright (Fernald 1950). Wright collected plants from Texas for Asa Gray and has many plants named after him (Wikipedia contributors).

State Ranking Justification [-]
There are three existing populations but the population size is only known in one of them. This population has hundreds of plants. There are four historical populations from the early 1900s and one from 1966 which have not been rediscovered although habitat still exists.
