Tomostima reptans (synonym Draba reptans), common names Carolina draba, Carolina whitlow-grass, Creeping whitlow-grass, and Whitlow-grass, is an annual plant in the family Brassicaceae that is native to temperate North America.
It is native to most of the contiguous United States, except for Florida, Mississippi, Kentucky, Virginia, Maryland, Delaware, and northern New England; to Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia in Canada; and to northwestern Mexico.
It is listed as a special concern in Connecticut, as threatened in Michigan, New York, and Ohio, as endangered in New Jersey, as extirpated in Pennsylvania, and as historical in Rhode Island.
The Ramah Navajo apply a poultice of the crushed leaves of the plant to sores.
The species was first described as Arabis reptans by Jean-Baptiste Lamarck in 1783. In 1934 Merritt Lyndon Fernald placed the species in genus Draba as D. reptans. In 2012 Ihsan Ali Al-Shehbaz, Marcus Koch, and I. Jordon-Thaden placed it in genus Tomostima as T. reptans.
