DistributionLimited to a small area of the southern Mountains, found only in Henderson and (rarely) Buncombe counties. This species was described in 1960 by Ernest O. Beal of NC State University.

This is a very narrow endemic species, found only in Greenville Co., SC, and the two NC counties listed above.

AbundanceVery rare in Henderson County, and presumed extirpated from Buncombe County. This is one of NC's Federally Endangered species, and it also carries a State Endangered status (by state rule).
HabitatThe species is limited to bogs and semi-shaded swampy ground. It does occur in ditches and a few other man-influenced habitats, including wet scrapes. According to Weakley (2020), much of its former habitat has been drained.
PhenologyBlooms from May into July, and fruits shortly after flowering.
IdentificationThis endangered species resembles several other Sagittaria species in its leaves. The several leaves are mostly narrowly elliptic to spatulate (somewhat wider above the middle), growing to about 1 foot tall but only 1-2 inch wide; it does have a short wedge-shaped petiole that merges into the blade. The flowering scape grows to 1-1.5 feet tall, with flowers clustered at 2-4 nodes along this stem. Each flower is about 1 inch wide, with three white petals. It should not be confusable with any other Sagittaria species in its limited sunny to partly sunny wetland habitats in Henderson County.
