Distribution

Sigesbeckia orientalis has a broad distribution in Africa, Asia, but has been widely naturalised outside this range. It is unclear whether it is native to Australia or has been introduced there.
Nomenclature

Academician Johann Siegesbeck who disagreed with Linnaeus' binomial nomenclature based on plants' reproductive organs, described his work as "loathsome harlotry". Linnaeus named the small, ugly weed Sigesbeckia orientalis after Johann Siegesbeck for revenge.
