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 meters tall. The leaves are composed of oval-shaped leaflets each about a centimeter long. At the base of each leaf are large, flat, pointedstipule s. The flower is purple-tinted white and 1 to 1.5 centimeters wide. The fruit is a lobed, gland-dotted legume pod narrowed between the seeds. It is up to 5 centimeters long and less than one wide.
