PULSE FAMILY. Leguminoss. 



6-15 inches high. Common on roadsides and in sandy 

 fields. Me., south to Va., and west to Iowa. 



Similar in many respects to the forego- 

 ing, but lower, more spreading, and the 

 steins and leaves fine-hairy. The leaflets 

 are shorter and blunt-tipped, the middle 

 one slightly stemmed and the lateral ones 

 steailess. The stipules (leafy formations 

 at the ba.se of the leaf-stalks) are broader 

 than those of the preceding species ; they 

 are pointed ovate. The, tiny standard of the floret is 

 wide-spread, and not curled up at the edges as in T. 

 agrarium. 3-6 inches high. Occasional or common 

 everywhere, especially on roadsides. 



This is sometimes called yellow sweet 

 clover, but its resemblance to clover is in 

 its character rather than its aspect. It is 

 a foreign flower which has established 

 itself in all waste places especially in our 

 seaport towns. The three leaflets are long, 

 blunt- tipped, and toothed. The light golden yellow 

 flowers are strung along in a delicate spike. The stem is 

 smooth and 2-4 feet high . Melilotus alba is a similar, tall- 

 er, white-flowered species. Both common everywhere. 

 Alfalfa or ^ P er ennial much cultivated for fodder 



Lucerne in the west and south ; naturalized from 



Medicago sativa Europe. Found in dry fields and sandy 

 wastes in the East. The three leaflets are 

 long and narrow, toothed toward the tip 

 which is obtuse, and furnished with a tiny sharp bristle; 

 each leaflet has a distinct stalk, and that of the middle 

 leaflet is bent ut;ward. The purple florets in short clusters. 

 12-25 inches high. Me., south to Va., and west. 



A generally smooth, tall beautiful peren- 

 nial with a branching stem, and compound 

 leaves of 13-25 or more bluish green, ellip- 

 tical leaflets set oppositely upon the 

 slender leaf-stem, in general appearance 

 like those of the locust tree. The cream
