Sabatia arkansana, commonly known as Pelton’s rose gentian, is an herbaceous annual in the gentian family. It was discovered in 2001 in several glades of the Ouachita Mountains in Saline County, Arkansas by John Pelton, a retired mechanic turned amateur photographer and naturalist. It is known only from two locations in this county and is considered critically imperiled as a result of the presence of nearby housing developments and due to the absence of a fire regime. In summer it shows attractive rose-purple flowers.
