Thank you Gerry  :). Do you think identification of the violet one is possible without detail about the corm ?
Francois - I'm not very good at identifying crocus from photos so I'll leave it to Thomas or Tony. I'm sure a description of the corm would be helpful if you have it.

Janis, is that Crocus michelsonii 'Turkmenian Night', or another dark form?
No, it is pot with my own selection. I haven't more Leonid's TURKMENIAN NIGHT. At that moment I have only his ODISSEY.

An identification please : I bought this crocus some years ago as Crocus serotinus ssp. clusii, but it reveals quickly to flower in spring. Nevertheless, as nomenclature is difficult, I'm not able to name it : an idea ?

Bio, I would guess this is a form of Crocus vernus, but to be 100% sure I prefer to have a look at the corm tunic.

Last year I purchased both C. oliviere ssp. oliviere and C. candidus var. subflavus from Minature Bulbs.
Sorry about the photographs taken today but they are seriously going over.
The first picture shows oliviere on the left (square pot) and candicus on the right (round pot)
I am not a botanist but I would say that the two crocus show differences. Oliviere has broader leaves than candicus, its flower is a rich egg yolk yellow and it has long roots coming out of the bottom of its tall, square pot. Candicus has narrower leaves and a much paler flower.
I think it would be difficult to give different written descriptions of the plants but seen side by side it is quite clear.

another identification please : this bulb was commercialised by Dix as Crocus candidus ssp. subflavus, but this name is not included on the alpine house website http://www.thealpinehouse.fsnet.co.uk/crocus%20pages/
nevertheless, I think that the very wide leaves are very specific : isn't it ?
From memory - Crocus candidus var subflavus = Crocus olivieri.  It shares the few broad leaves and some other key features of Crocus olivieri.  The name you have has been attached to a plant in commerce not a wild specimen.  It is not a subspecies.  Ibrahim posted a pic of wild C candidus last year which was a pale orange but not the vivid yellow of this plant.
edit - I now see Gerry has answered in the same vein

Crocus vernus albiflorus with a yellow throat would be a new find!  Could it be Crocus sieberi? or a biflorus ssp?  Show is a side view ;)

To add to the above discussion a patch of a crocus bought as Crocus olivieri balansae -the flowers are not stripped on the back, as i thought theyy would be, but are a rich egg-yolk yellow, the leaves are not very broad at all. I suppose that this shows that when it comes to yellow crocus there's a lot of misnamed stuff out there.

My vote is Crocus tommasinianus or a hybrid of that species and Crocus vernus.  The complete absence of markings on the outside of the flower throat plus the lilac colour suggest C tommasinianus but the overall shape and petal width hint at C vernus blood.

Hi Tony. I will try and get a side shot of it tomorrow. It was bought as Crocus vernus albiflorus and I was just trying to find the thread where Janis was apologising for any mix up, but I couldn't see if any name for it dbeen resolved.

Simon, your C. olivieri looks very much like C. flavus!

Tony you might be right about Bio's Crocus, havn't noticed the white stem
which points for tommie-blood.
