Summary ⁷

Senna obtusifolia (Chinese senna, American sicklepod or sicklepod) is a legume in the genus Senna, sometimes separated in the monotypic genus Diallobus. It grows wild in North, Central, and South America, Asia, Africa, and Oceania, and is considered a particularly serious weed in many places. It has a long-standing history of confusion with Senna tora and that taxon in many sources actually refers to the present species.

Description ⁸

Annual or short-lived perennial shrubby herb, up to 2 m.
