Mariosousa is a genus of 13 species of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.[3] Members of this genus were formerly considered to belong to the genus Acacia.[1]

Restricted in range to Central America, Mexico, and the southwestern United States, members of the genus are trees or shrubs bearing alternate, bipinnately compound leaves—each with a swelling at the base of the petiole—and white- to cream- or yellow-colored flowers. The flowers are typically borne in elongated, bottle brush–like spikes. The fruits that later replace these flowers are markedly flattened pods.
