Agalinis harperi, commonly known as Harper's false foxglove, coastal plains false foxglove, or St. Marks false foxglove, is a species of flowering plant in the family Orobanchaceae. It is a hemiparasitic annual herb native to the southeastern United States, Central America, and the Caribbean.[2][3]
Description
Agalinis harperi is an annual herb growing to about 30 in (76 cm) tall.[3] It produces rose-purple flowers with yellow lines and purple spots in the throat.[3] Flowering occurs from August to October.[4][3] The fruit is a capsule.[3]
Distribution and habitat
Agalinis harperi is native to the southeastern United States, Central America, and the Caribbean.[2] Plants of the World Online lists it as native to Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Texas, the Bahamas, Belize, Cuba, Honduras, Jamaica, Nicaragua, and parts of Mexico.[2]
In the southeastern United States, it occurs primarily in Coastal Plain habitats, including wet pinelands, flat pine woods, pine savannas, flatwoods, bogs, and interdune swales.[4][3][1]
Taxonomy
Agalinis harperi was first described by Francis W. Pennell in John Kunkel Small's Flora of Miami, published on 26 April 1913.[5] The type specimen was collected by Pennell at St. Marks in Wakulla County, Florida, and the holotype is held at the New York Botanical Garden herbarium.[5] Although IPNI records the family placement as Scrophulariaceae in the original treatment, modern sources place the species in Orobanchaceae.[5][2][1]
The species has also been treated under the name Gerardia harperi.[5][2] Hays established the nomenclatural priority of A. harperi in 1998.[4]
Conservation
NatureServe ranks Agalinis harperi as G4?, indicating that it is apparently secure globally, though the rank is uncertain and NatureServe notes that the global status needs review.[1] The global status was last reviewed on 31 January 2001.[1] NatureServe lists the species as N4? in the United States, S1S2 in Georgia, S3? in Louisiana, S3S4 in Mississippi, and S1 in South Carolina; Florida has not been reviewed.[1] The species has no status under the United States Endangered Species Act.[1]
