crocus identification

[Thomas Huber]

Maggi, don't put your German down, before I have heard you talking!
Working out this together with you would be great, but not in next future 

[Maggi Young]

Thomas, it is MANY MANY years since I was speaking German every day   
Reading it is another matter, much simpler!  

We have many years ahead of us, I believe, so there will be time to do this work later !!

Would someone post a picture of the true Crocus 'Lady Killer'?  Is it indeedCrocus chrysanthus?

I ask as a good friend wrote today: "My objection to some books carelessly putting it into chrysanthus comes from my semi-classical education where chrysos means gold. Hence in the early crude classifications the yellow group was chrysanthus and the blue-white ones into biflorus; this has been immeasurably refined during the past 50 years as you see. It seemed obvious that ‘Lady Killer’ belonged into the old lumped biflorus, lacking any yellow. So whenever I saw ‘Lady Killer’ in bulb catalogues labelled a variety of chrysanthus I always said “bleep!”  I hope you work out why."

I planted these crocuses last autumn from supermarket's Crocus botanical mix -bag. They are some sort of Crocus chrysanthus (?), something very common and cheap most likely, but does anyone have any idea what cultivars they might be?
