Rank Reasons
Lechea racemulosa is a wide-ranging perennial herb in old fields, woodlands, and woodland margins occurring in the eastern United States, centered on the Appalachian Mountains, from Massachusetts and New York west to Indiana and south to South Carolina west to Louisiana. Threats include development, rights-of-way maintenance activities, succession, and invasive species. Little is known about trends, but with a large range extent and large number of occurrences, tolerance of light disturbance, and no obvious intrinsic vulnerabilities, this species is considered secure.
Range Extent Comments
Lechea racemulosa occurs in the eastern United States, centered on the Appalachian Mountains, from Massachusetts and New York west to Indiana and south to South Carolina west to Louisiana, it is possibly historic and disjunct in Iowa and Missouri (FNA 2015, Weakley and the Southeastern Flora Team 2024). Range extent was estimated to be over 700,000 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 100 occurrences rangewide (GBIF 2024, iNaturalist 2024, NatureServe 2024, SEINet 2024). However, anecdotal comments support the likelihood that there are over 300 occurrences rangewide.
Threat Impact Comments
Although threats are not widely documented, this species is potentially threatened by development, rights-of-way maintenance activities, succession, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, tolerance of light disturbance, and no obvious intrinsic vulnerabilities.
Ecology & Habitat

Habitat

Lechea racemulosa grows in "old fields, woodland margins, other dry, sandy, open sites," including dry pine and other woodlands (FNA 2015, Weakley and the Southeastern Flora Team 2024).
