Other info. - This introduced and weedy species can be found in a handful of scattered Missouri counties. The plant is easy to identify becasue of its big leaflets, big yellow flowers, and sickle-shaped (falcate) fruits.
The seeds of this species were boiled and made into a tea which was used to treat headaches, fatigue, and stomachaches. The seeds are also used as a coffee substitute. A tea made from the fruits was used to treat headaches, herpes, and arthritis. African natives used the leaves to make a protein paste.
A nice lady from Africa sent me an email to let me know that she has been eating C. obtusifolia all her life. She serves it with eggs.
A modern synonym for this species is Senna obtusifolia (L.) H.S. Irwin & Barneby
Old synonyms included Emilista tora (L.) Britton & Rose and Cassia tora L. (both these names were apparently missapplied as C. tora may be a distinct species.)
