From the genus name, Amorpha, from Ancient Greek ἄμορφος (ámorphos, “shapeless, deformed”), because the flowers have only one petal rather than the three of other genera in the subfamily Faboideae.

Amorpha is a genus of plants in the pea family Fabaceae. All the species are native to North America, from southern Canada, most of the United States, and northern Mexico. They are commonly known as false indigo. The name Amorpha means "deformed" in Greek and was given because flowers of this genus only have one petal, unlike the usual "pea-shaped" flowers of the Faboideae subfamily. Amorpha is missing the wing and keel petals.
