Are both Hottonia and Othonna geniuses of plants?
Othonna Othonna is a genus of African plants in the sunflower family.
Senna obtusifolia 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.
