This is near to .4. Boissicuana v. nikoensis which is an extreme 

 form of A. Boissicuana, but differs from it by having more caespitose 

 stems and more stellulate-haired leaves. By its caespitose habit it 

 somewhat resembles to A. Fauriei, but is readily distinguishable by its 

 narrower eauline leaves which are entire or inconspicuously serrulate 

 in their margines and more slenderer straight siliqucs as well as more 

 elongate racemes.
