Aeschynomene rudis is a species of flowering plant in the legume family known by the common name zigzag jointvetch. It is native to South America[1] but it is known from other continents, including North America, as a noxious weed, especially of wet areas such as rice fields. It is aquatic or semi-aquatic, growing bristly, glandular stems near or in water. It grows up to two metres tall. The leaves are composed of oval-shaped leaflets each about a centimetre long. At the base of each leaf are large, flat, pointed stipules. The flower is purple-tinted white and 1 to 1.5 centimetres wide. The fruit is a lobed, gland-dotted legume pod narrowed between the seeds. It is up to 5 centimetres long and less than one wide. As the pod dries it breaks into segments, each segment containing a seed. The hard, shiny seed is kidney-shaped and 2 or 3 millimetres long.

Aeschynomene rudis es una especie fanerógama perteneciente a la familia de las fabáceas.
Es nativa de América del Sur[1] pero se sabe que habita en otros continentes, como en América del Norte, habitando donde hay malas hierbas nocivas, especialmente en las áreas húmedas como los campos de arroz.
Es una planta acuática o semiacuática, erizada, glandular cuando está cerca del agua. Crece hasta dos metros de altura. Las hojas están dispuestas de forma oval, folletos cada uno de un centímetro de largo. Las bases de cada hoja son grandes, planas, con estípulas. La flor es de color púrpura pintada de color blanco y de 1 a 1,5 centímetros de ancho.
El fruto es una vaina leguminosa lobulada de hasta 5 centímetros de largo y menos de uno de ancho. Cuando la vaina se seca se divide en segmentos, cada uno de los segmentos contiene una semilla. Su brillante semilla tiene forma de riñón de 2 o 3 milímetros de largo.
Aeschynomene rudis fue descrita por George Bentham y publicado en Plantas Hartwegianas imprimis Mexicanas 116. 1843.[2]
Aeschynomene: nombre genérico que deriva de las palabras griegas para una planta sensible utilizado por Plinio el Viejo, aischynomene, deriva de aischyno = "vergüenza", y del latín Aeschynomene para una planta que se encoge cuando se toca, una planta sensible.[3]
rudis: epíteto latíno que significa "bruto, sin labrar, grueso"[4]
