Wildflowers: An abnormality of Sedum (album)?

I have these photographs for at least 2 years without ever being able to identify the species. Family: Crassulaceae, genus Sedum, sp. album? It obviously seems to be an abnormal case of Sedum...... Any ideas. duffy

 

Two years ago I photographed this plant believing it to be a Sedum. Two days ago I found myself in the same place, low and behold, I found other specimens but this time in flower. The photographs are attatched. Instead of being a Crassulaceae it is a Brassicaceae, Anthionema saxatile to be exact. I thought it might be interesting to see both sets of photographs.

 

Thanks for the update. I wonder if the "leaf crush and smell test" would have narrowed this down to Brassicaceae earlier on (since all(?) Brassicaceae have sulfurous compounds, they have a fairly distinctive smell).

 

That was funny!
Check for Aethionema.

 

I grow a number of Aethionema species - I never thought to check them for smell but will have to do so!
