Anthyllis hermanniae Yellow Kidney Vetch
More an Eastern Mediterranean species, this shrub has very small flowers and inrolled greyish green leaves. There are supposed to be spines at the ends of the branches but on the plants we saw they weren't that obvious and you wouldn't immediately call this a spiny species.
