Erigeron bonariensis


Erigeron: From the Greek eri 'early' (or ear 'spring') and geron 'old', possibly alluding to the hairy seed pappus, or perhaps to the hoary appearance of the leaves of some species in the spring.

Similar Taxa

E. bonariensis is easily distinguished from the other common weedy Erigeron spp. by its narrow leaves, usually twisted and with wavy or undulate margins and by its larger flower heads (capitula). E. bilbaoanus has its bracts around each capitulum (the involucral bracts) much less hairy than those of E. bonariensis and E. sumatrensis, the latter two being distinguished most readily by the twisted vs flat leaves.
