yet another from the limestone mountain pastures

I am (almost) persuaded that this is a Crucifer, but would greatly welcome a better informed view.

 

Yes, crucifer. You can see the siliques forming below the flowers.

 

Thanks Daniel. I am thinking Arabis spp. and maybe Arabis alpina. Any thoughts?

 

In what country was the photo taken?

 

This was in Italy in the Parco d'Abruzzo south of Rome. Found in a pasture at 1500 masl in the limestone mountains.

 

I only have decent resources from Switzerland, but it does look like a good match with Arabis alpina as presented in those books.

 

Thanks Daniel, I think that is a tentative id. I hope others may also care to contribute their thoughts.

 

You can look up a lot of Arabis with maps of locations found on this page:
arabis - RISULTATI DELLA RICERCA

 

Many thanks Wendy, some excellent information there.
