Sabatia arkansana (Pelton's Rose-gentian) J.S.Pringle & Witsell 2005
annual plant species in the gentianaceae family
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.
Lithospermum parviflorum (Softhair Marbleseed) Weakley, Witsell & D.Estes 2011
perennial plant species in the boraginaceae family
Lithospermum parviflorum, commonly called Eastern Prairie Marbleseed, is a species of flowering plant in the forget-me-not family. It is native to the eastern North America. This species is a robust perennial. It produces a cyme of cream colored flowers in late spring and early summer. Although widespread, this species is spotty and uncommon throughout much of its range. Its preferred habitat, somewhat dry calcareous woodlands, barrens, and glades, has been heavily impacted by agriculture and other land-use changes. The only area this species is considered secure in is the Ridge and Valley
