This one is really true C. olivieri subsp. istanbulensis collected at it's locus classicus (not by me, of course). By flower not possible to separate from type subspecies, but it has different leaf morfology and corm tunics. It is first blooming in my collection. Corm from Ibrahim still didn't start flowering. I think this is first picture of this extreme rariety in our forum. As I hear, in nature there are not more than 100 plants left.Janis

On my collection they flower after than standart olivieri. Now all my olivieri are in full bloom but istanbulensis is just showed the nose.

We have been looking at diversity in Crocus olivieri within Bulgaria. This species has a very fragmented distribution within Bulgaria. We have not yet visited the populations in the west of the country, but the central populations we have seen did not exhibit much diversity other than colour of floral tube. One of the populations we know on the Black Sea coast has more diversity in markings on the outer petals. The most common forms are still those with pale flower tubes, but here some are speckled and purple tubes are not unusual. Some of the purple tubed flowers also have markings, which is something we have not seen in the population in Central Bulgaria.
Crocuses which we are naming chrysanthus by my opinion really are group of species and quite variable. I saw extremely variable population not far from Tashkent, which is quite far from Turkey in Europe - there almost each plant was different. I put puts with all chrysanthus acquisitions together and then it is possible to see that some are very large, some small and smallest are some from Greece and W Turkey. There are very uniform populations, too - on yaila near Kan gec (not far from Elmali) - there all plants (and they are millions there) are very uniform. Janis
