Most Vigna plants are small herbs. Some can grow into larger subshrubs. Their leaves are pinnate, which means they are divided into three leaflets. They grow flowers in a shape called a raceme. These flowers can be yellow, blue, or purple. The fruit is a legume pod. This pod holds the seeds of the plant.

Scientists used to group these plants with a group called Phaseolus. Now they know they are different. They look at the pollen structure to tell them apart. They also look at the biochemistry of the plant. They check the style and the stipules too. They also look at the stigma structure to separate them from the Dolichos group.
