This plant species is characterized as aquatic or wetland herbs, often annuals, with a rooting pattern occurring at the nodes. Notably, it features distinctive white, upright, spindle-shaped pneumatophores that cluster at the nodes of the floating stem. Its leaves are simple, alternate, broadly oblong-elliptic in shape, with smooth surfaces and prominent main veins. The flowers are white and typically appear singly in the axils or at the ends of branches.
