Can you identify this saxifraga and this Arabis? . Thanks very much!

I'm not good at alpine ID but I think the yellow one is a Draba

[newstart]

It looks awfully similar to a saxifraga, can any one else confirm this for me? Thanks Mark for your input.

The flowers on saxifrages have 5 petals.  Your yellow-flowered plant has flowers with 4 petals, hence Brassicaceae, and likely a Draba, as Mark said.

Oh excellent does anyone know a species. it would be great to know.I found this via RHS enclopedia and the net showing it better- http://www.mun.ca/botgarden/images/content/55-843502169.jpg Does this look very similar. It seems one of the few Drabas with very short stalks and very clustered , many flowers, to a stalk. Am I hot on the trail do you think...? Does anyone know the Arabis seems a common one. I think it caucasica 'snowcap'. My dad never labels his alpines sorry!. I got the cuttings from him of course. As they flower they end up on the forum.

Thanks!

I count five petals and it looks very much as S. sancta or something close.

Oops, right you are!

Ive sorted the Arabis so no worries there now. It does have five petals in fact I should have checked it when Lori first mentioned about the petals. Easy mistake as the flowers are only about 4mm across. I could have done a bigger picture as well and been with in the Kb limit still. Well spotted Gote! . I will have a look on the net to see how close the photo is to the species you say. If it is very close if not the same then thank you for your help everyone.

and so what IS  the Arabis , David?

[newstart]

Arabis alpina ssp. caucasica 'Snowcap' syn. 'Schneehaube' . Seems that its easily found on net and looks identical. Certainly caucasica. Thanks Maggie.

It could also be one of the S sancta hybrids S x eudoxiana such as S "Gold Dust" or "Haagii".  

Best place to look for up to date names and pictures is on the Saxifraga Society database: Saxbase

I beg to disagree.
Haagi has more cylindrical leaves and is more glaucous. 'Gold dust' is not as dissimilar but has linear leaves. It looks exactly as the plant I grew under the name sancta fiftyfive years ago and it fits the illustration in 'porophyllum Saxifrages' by Horny/Webr/Byam-Grounds. My Sancta nannot have been gold dust since that one was launched in England 1950 and could not have reached Sweden in 1955. I also grew haagii at the time and the one I grew fitted the description well.

I have looked on the net in different places and found S. sancta to be the closest. The foliage is different on  hybrids S x eudoxiana  "Gold Dust" or "Haagii". Most things are resolved when I  click on google images and ask for a second person on the forum for there confirmation. You guys are really good at it. Lets face it saxifrage is so diverse and many similar ones make it confusing. Thanks everyone.
