larger seeds and smaller leaves, and also in bearing very long stolons. The 

 Indian plant appears to be of more tender habit, with curved pods, 

 narrower, smaller seeds, and larger, thinner leaves. Moreover, the present 

 plant differs from A. arenosci SCOP, in having longer pods, smaller flowers, 

 and leaves with more rounded lobes.

My specimen doss not quite agree with the description of A. alpina 

 LINX. It seems to me that the plant differs a little from the type in its 

 individual character only. The leaves of the present form are subentire, 

 while those of the type are more or less dentate.
