Bobotov kuk

J. heuffelii is native to Bobotov kuk.

In old listings Bobotov kuk is said to be in Yugoslavia or former / ex - Yugoslavia.

Now that Yugoslavia no longer exists we will all heve to correct our listings.

Bobotov kuk is the is highest peak of Durmitor mountain and 4th highest peak in Montenegro.

So correct listing would be:
S. heuffelii ex Bobotov kuk, Montenegro

Yellow flowering species mentioned below picture is probably J.heuffelii

Yes, yellow flowered specied mentioned there can be nothing else but J. heuffelii subsp glabra.

On my opinion there is S. marmoreum on the photo.
