Well it's a member of the Fabaceae family but that's about as far as I can get for the moment. Were there any flowers left? Do you know what colour they were?

No, no flowers. They had this sort of fruit (?) on the second photo.

Yes, those are the seed pods but it's hard without any flower colour.

It could be something like Trifolium but i'm not sure.

It's definitely in the Fabiaceae, the same family as Trifoliums. But I am leaning towards a Dorycnium. Maybe D rectum????

Could you tell us where the plant is growing and what time of year you photographed it? That's very important when asking for help ID'ing any outdoor plant ;)

I took the photo yesterday, the plant is growing at 400 m. Not so far from a dam

400m in what part of the world? ;) Sorry, I should've been more specific with my question.....

It's in Sardinia apparently.

Yes it is in Monti Mannu,Sardinia,Italy.
