Erigeron floribundus (weed) (Kunth) Sch.Bip. - (broadleaf fleabane)

This weed is often treated as "Conyza sumatrensis (Retz) E. Walker" which is a synonym of E. floribundus and not the same as Erigeron sumatrensis according to World Flora Online.

The plant is an annual herb, native to the Americas but introduced and often invasive in various other temperate and subtropical regions. It grows in disturbed habitats like roadsides and agricultural fields (e.g. soybean). The plants reach a height of more than 1 m and have small, whitish, spherical flower heads. The seeds easily spread through the air.
