The medicks (including Lucern) are distinguished among British plants 

 by their little legumes coiling up spirally, as they ripen, into a 

 ball resembling a snail-shell, the outer edge often fringed with 

 minute teeth. In Medicago lupuUna the spire is incomplete. 



The legumes of the furze, the clovers, the trefoils, the melilots, the 

 saint-foin, and the rest-harrow, are straight, very short, and 

 seldom contain more than one seed. Those of the melilots are 

 wrinkled. 



Those of the lotus, in its different species, are long, slender, cylindrical, 

 and smooth. 



Those of the bird's-foot are formed of several single-seeded joints, 

 which readily break apart when ripe. 



Those of any other Leguminosse wild near Manchester resemble small 

 peas or beans. 



HABITATS AND LOCALITIES.
