Synonyms[1]

Sigesbeckia is a genus of annual plants in the aster family.[2][3] St. Paul's wort is a common name for some of the species.[4]

Origin

Sigesbeckia is named for a botanist Johann Georg Siegesbeck, who was a strong critic of Carl Linnaeus's botanic classification system. He was known to refer to it as "Loathsome Harlotry" because of the focus of the system upon the presence of (or lack of) sex organs in plants and their locations and groupings.[5]

Classification

Sigesbeckia is related to a group of South American plants variously known as subtribe Espeletiinae or the Espeletia complex, which include genera such as Axiniphyllum, Espeletia, Polymnia, Smallanthus, Rumfordia, Trigonospermum, and Unxia.[6][7]

Some African Sigesbeckia species were transferred, at least by some authors, to Guizotia.[8]
