At first many thanks for sharing these beauty. All of us we agree that Dave's crewei or whatever is a splendid plant.
Dave, I named mine isauricus, as you see in second picture it has five lieves ( crewei can't have 5 ) If you mind for blackish anther, isauricus sometimes may have.
The features what I accept for isauricus; Leaves usually 4-7; anthers yellow but often with agreyish connective; filaments 4-7 mm, filiform (S.W. & S. Anatolia)
For your C. biflorus subsp. nubigena, I have record in Antalya and in Muğla. Korkuteli is very cloase to Muğla so location is right. I mind distributions because of C. biflorus ssp. are not faithful often.
Crocus adanensis and Crocus paschei occur in same province that is why I asked about.
I believe that your C. adanensis is very good sample this species. C. paschei has very nice golden center,
out side of petal speckled buf, shape of flovers seems me different. I have seen some pics of this crocus in a gallery of my riend. I would not like to use here.
