Flora of the Alps

Dear all,

I don't know if this is the right sub, but I'm looking for a good Flora for the Alps. My current experience with floras is just Heukels, the standard for the Netherlands, where I live. It claims to be the most complete, has determination keys, genus index and B&W drawings, see pictures.

I was hoping to find something similar for the Alps, which I visit at least once a year. I think I'd have the best shot looking for a book in German, as Bavaria, Switzerland and Austria are alpine, and I speak the language. So far, I've found a few things. Most of them look like rather casual/popular selections and not really something that'd have keys in it. One of them sounds more thorough though: Kosmos-Alpenflora (link), but I can't find any examples of the contents.

Does anybody have experience with that particular Flora, or do you maybe have suggestions?

Thanks in advance!
