First report of Conyza sumatrensis in Bulgaria


Conyza sumatrensis (Asteraceae) was reported in 2009 in Bulgaria where it is relatively widespread, being recorded in 7 out of 20 floristic regions. The species grows mainly in man-made habitats but it was also found in some secondary grasslands. C.;sumatrensis is thought to have been present in the country for at least 2 decades during which period it was probably confused with C. canadensis and C. bonariensis. Observations suggest that the species is invasive in Bulgaria.
