Vigna dalzelliana is a perennial herb with yellow flowers that commonly is used as fodder.

[1] The plant is poorly understood and was previously confused with its relative Vigna minima.

The herb's inflorescence is axillary, meaning it rises from the same node as a leaf rather than from the end of a stem.

[4] The plant is common to Thailand, Cambodia, India and Sri Lanka, and grows between 5–2,500 m (16–8,202 ft) in altitude.

It grows in shady wet highland slopes where the plant can root from stem nodes.
