Tradescantia longipes Anderson & Woodson is reported from Montgomery County, Arkansas, thus confirming its occurrence in the southeastern United States. Previous records are considered uncertain or erroneous. This species is found to differ consistently in leaf and bract pubescence from the closely related T. hirsuticaulis Small. Three subacaulescent specimens from Arkansas and South Carolina closely resembling T. longipes are concluded to belong to T. hirsuticaulis, which has not been previously recorded with a subacaulescent habitat.
