lt is the short loose axillary racemes, the hard cup- 
shaped calyx, slit on the upper side, and the broad vexillum 
which overlaps the other petals and is usually absolutely 
parallel with them, that distinguish Zdwardsia from Sophora, 
whose racemes are terminal, calyx soft and regularly 
toothed, and vexillum narrow and recurved, or reflexed.
