Vernonia acaulis (Walter) Gleason. Flatwoods Ironweed. Phen: Late Jun-Aug; Aug-Oct. Hab: Longleaf pine flatwoods, moist ecotones, and moister sandhill situations, in the Piedmont in dry rocky woodlands, hardpan woodlands, bluffs, and barrens. Dist: Coastal Plain and lower Piedmont of ne. and nc. NC south to sc. GA (Thomas and Grady counties). The single apparent record from FL is a collection listed from Polk County (P.O. Schallert 880) with no additional locality information. The specimen is indeed V. acaulis, but it is likely that the locality information of this specimen was not assigned correctly. Schallert notoriously misapplied specimen numbers and localities to the wrong collections, and given the disparate collection localities and chronological disorder adjacent to this collection (in addition to far disjunction), we consider the c. FL record to be in error. The specimen of Schallerts could literally have been collected from anywhere in the southeastern US based upon his other collections.
