Marshallia trinervia (Walter) Trelease. Colonial Barbara's-buttons, Broadleaf Barbara's-buttons. Phen: Jun-Jul. Hab: Moist rocky streambanks and in calcareous clays, more often in shady habitats than its congeners. Dist: C. TN, south to s. AL and s. MS (Sorrie & Leonard 1999) and e. and w. LA(!). Reported for VA by C; the documentation is unknown. Michaux gave his Persoonia latifolia as "Habitat in montosis Carolinæ". The only moderately recent NC record (Macon County) appears to be from the yard of the director of the Highlands Biological Station at the time; other herbarium specimens from his property are of clearly cultivated material. The SC record from Walter seems dubious on biogeographic grounds; the only other purported SC specimen (from 1973) is misidentified.
