3. MELILOTUS ALTISSIMA, Thuillier. 
This species is readily distinguished by its dull colored, some- 
what flattened, pods, which are distinctly pubescent or scabrous ; 
the standard, wings, and keel of the flower are equal in length. 
Many of the numerous localities given for this species in Can- 
ada and the United States probably belong to M. officinalis, 
Desr. I have not, so far, seen a Canadian specimen of M. 
altissuma.
