FAMILY: Compositae (Asteraceae)

HABIT: Densely tufted perennial from a stout, vertical rootstalk, flowering scapes 5-25 cm; flowering late April to mid May; fruiting May, June. SIMILAR SPECIES: A distinctive species unlikely to be misidentified as any other native Ohio composite. No other species shares its unique combination of habitat, appearance, and blooming date. TOTAL RANGE: Tetraneuris herbacea is known only from Ohio, the Bruce Peninsula and Mantioulin Island, Ontario, and two counties in Illinois. It is apparently extirpated in Illinois (M. Bowles, pers. comm., 1981). A recently discovered population along a roadside ditch in the Upper Peninsula of Michigan may be natural or could have been introduced
