The flowers are zygomorphic with a gamosepalous calyx of four sepals and a pink, papilionaceous corolla of five petals. The androecium is diadelphous with heterodinamous anthers, and the ovary is superior, sessile, and pluriovulate. The fruit is a linear legume with a straight margin and a glabrous brown epicarp.
