(Scrophulariaceae), Swamp wood-betony, is a hemiparasitic, short-lived perennial member of the Scrophulariaceae family. It ranges from Massachusetts to Georgia on the east coast, and west to North Dakota and Missouri, and is also present in the Canadian provinces of Saskatchewan, Manitoba, and Ontario. Although P. lanceolata is common in some mid-western states and is not considered to be rare on a global scale, it is rare in most eastern states in which it occurs, and is known only from historic records in Delaware and Kentucky. In New England, P. lanceolata is currently present at six sites in Connecticut, and two sites in Massachusetts. Despite regular field visits, the species has not been observed since the mid-1990's at one of the sites; but it was relocated at the other site in 2001. It has not been found in other New England states, but was known historically from nine other locations in Massachusetts and approximately 30 in Connecticut (herbarium specimen data are not precise enough to determine the exact number of historic locations). Pedicularis lanceolata populations in New England appear to be disappearing or declining due to habitat loss, habitat modification, exotic species invasion, and ecological succession.
