Echinacea Moench (Asteraceae)
Echinacea is represented by three or four species in North Carolina. Echinacea laevigata (C.L. Boynton & Beadle) S.F. Blake is federally listed (Fed T, S1S2 G2G3). Echinacea purpurea (L.) Moench (State SR-O, S1 G4) was delisted at the state level in 2021, but continues to be tracked by the Natural Heritage Program, along with E. pallida (State SR-D, S1 G4).
Federally listed taxon—
Echinacea laevigata (Fed T, State T | S1S2 G2G3)
Habitat. Glades and woodlands over mafic or calcareous substrates. Associates include
Silphium terebinthinaceum Jacq., Solidago ptarmicoides (Torr. & A. Gray) B. Boivin, S. rigida L.
var. glabrata E.L. Braun, Liatris squarrosa (L.) Michx., and L. squarrulosa Michx.
Range. Eastern US, historically from Arkansas to Pennyslvania, but no longer extant in those two states.

Urbatsch et al. (
Flora North America, vol. 21) regarded this species as absent in North Carolina, however, Weakley (
Flora of the southern and mid-Atlantic states, 2012) considered that many eastern populations referred to
E. pallida may in fact be
E. simulata. Currently, the NC Natural Heritage Program refers populations of narrow leaved
Echinacea in the state to
E. pallida (see above). Both species are treated in the present work to facilitate resolution of the distribution of these taxa.
