It is the short loose axillary racemes, the hard cup- 

 shaped calyx, slit on the upper side, and the broad vexillum 

 which overlaps tlie other petals and is usually absolutely 

 parallel with them, that distinguish Edwardsia from Sophora, 

 whose racemes are terminal, calyx soft and regularly 

 toothed, and vexillum narrow and recurved, or reflexed
