Anthyllis vulneraria subsp. valesiaca

Anthyllis vulneraria is a very common species in the Alps and the Aosta Valley, and is a highly polymorphic plant. It therefore has numerous subspecies; among these, one of the most interesting is the valesiaca subspecies, which is endemic to the Western Alps. Indeed, the subspecies name refers to Valais, a region of the Swiss Alps where this plant was probably first observed and where it is widespread. 

A xerophilous (one that thrives in dry conditions, i.e. one that can grow where water is scarce) species, it is found mainly in dry, siliceous grasslands, at altitudes ranging from around 1,100 metres to over 2,800 metres. It is easily distinguished from other subspecies of Anthyllis vulneraria by its flowers and calyx teeth, which are often purple in colour. 

The specific name vulneraria derives from the Latin ‘vulnerarium’, itself derived from ‘vulnus’ (wound), alluding to this species’ ability to heal sores and wounds.
