Its copious bright yellow flowers are carried on erect multi-branched inflorescences.[2] The species was formerly placed in the genus Cassia.
It occurs naturally in Cameroon, Central African Republic, DRC, South Sudan, Ethiopia, Kenya, Tanzania, Mozambique, Zimbabwe, South Africa and Eswatini.[1] It was introduced to several Indian Ocean islands and became naturalized in far northern Madagascar.[3] [4] [5]
