Taxonomic Comments
This record represents the broad concept of Agalinis purpurea, including A. paupercula as the variety A. purpurea var. parviflora, following FNA (vol. 17, 2019). In contrast, Kartesz (1994) recognized A. purpurea and A. paupercula as distinct species. Thus, the full species A. purpurea of FNA (vol. 17, 2019) is broader than that in Kartesz (1994).

Rank Reasons
Agalinis purpurea is a widespread annual forb in a variety of open habitats in eastern and central North America from Nova Scotia west to Ontario in Canada and south in the United States to Florida and Texas. Threats may include development, recreation, invasive species, and roadside maintenance activities. Little is known about trends, but with a large range extent and over 600 occurrences, this species is considered secure.
Range Extent Comments
Agalinis purpurea occurs in eastern and central North America from Nova Scotia west to Ontario in Canada and south in the United States to Florida and Texas. Range extent was estimated to be over 5 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1993 and 2024, it is estimated that there are over 600 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024).
Threat Impact Comments
Although threats are not widely documented, Agalinis purpurea is potentially threatened by development, roadside maintenance activities, recreation, invasive species, and other threats in some places, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species.
Ecology & Habitat

Habitat

Agalinis purpurea grows in "woodlands, wet meadows, roadsides, in a wide variety of open habitats" (Weakley and the Southeastern Flora Team 2023), including "moist sandy soils at margins of ponds, lakes, streams, bogs, freshwater and brackish marshes, ditches, pine barrens,... prairies, coastal swales, dry soils, margins of pine plantations, inundated marl prairies" (FNA 2019).
