Draba identification

[Robert Pavlis]

1) Does anyone know of a plant key on line for Drabas?

2) I've been looking up info on Draba korabensis. Most pictures in Google are yellow as is my plant. a few describe it as white with a tall flower spike. There is not much info on this plant on the net. anyone know the true color?

As this plant is a Bulgarian Balkan endemic, I'd be inclined to follow the description in the Red Data Book  of Bulgaria -
http://www.e-ecodb.bas.bg/rdb/en/vol1/Drakorab.html  -where it is shown as having white flowers on a tallish stem.

 Also this image of an herbarium  isotype sheet via Jstor ....

I don't know, though, of an online key for Draba.

Draba korabensis is also described with "Petala alba" (Schulz, 1927, good description if you read latin ) and in the Leucodraba section (Buttler, 1967 but I don't read german). In the key of Flora europaea, it is under "flowers usually white or cream". Seems to be white...
Just a precision : Maggi, this is not a Bulgarian endemic, read the general distribution in your first link

Oh yes, sorry,  I had Bulgaria in my head - it it a Balkan endemic. I have made the correction.

Hello
I had this question as well. I received in the 2015 seed distribution some Draba korabensis seed. Sown 27/1/16. Lots of germination. I don't have a good image of the flower but they were definitely yellow.

Below is a better image taken 25/2/17 - original sowing 27/1/16. No special seed treatment.

Looks like the common Draba aizoides

Unfortunately it seems these days that most Drada seed I get from the AGS is aizoides even for some of the really well known ones.
