Mr. J. K. Metcalfe introduced this plant into cultivation and demonstrated its use- 

 fulness as a forage plant. It has a large thickened root and produces prostrate stems 

 frequently 3 to 4 meters long. The crop which can be produced on an acre of ground 

 is a large one. The pods and seeds are large, a fact which adds to the feeding value. 

 The plant was called "Metcalfe bean" in honor of the introducer.
