On the Scottish mountains, in a sandy soil. 



Perennial. July. 



Root woody. Whole herb remarkable for its shining silky hairiness, 

 which the delineator of Engl. Bot., generally so correct, has 

 scarcely at all expressed. Leaves all radical, stalked, with a 

 pair of large, ovate, pointed, membranous, veiny stipulas, united 

 to the base of each footstalk ; leaflets numerous, opposite or 

 alternate, ovate, acute, the upper ones gradually smaller. Foot- 

 stalks often permanent in a naked state, but not hardened into 

 spines. Flower-stalks solitary, or in pairs, erect, firm, hairy, 

 taller than the leaves. Fl. of a rich blueish purple, rarely white, 

 in round dense heads, with an oblong bractea to each flower. 

 Cal. tubular, clothed with dense, close, black as well as white 

 hairs ; its teeth short, bluntish. Legume ovate-oblong, pointed, 

 brown, silky, with a membranous partition. Stigma permanent, 

 somewhat capitate. 



A very handsome species, even in a dry state, the flowers often 

 retaining much of their colour, and the herbage all its bril- 

 liancy.
