Crocus to identify? Post them here....

This unusual flower has appeared in the last few days from JJA Caspius seed 2002.Is it a natural freak or caused by a virus. Other flowers in the same pot are normal.

  Jım,
  This can be seen often in the crocuses even in the wild. It will flower normally next year.
  I don't know exactly the reason but it is not a virus.

Of course it isn't virus. Large, well grown crocus corms sometimes forms additional petals in flower, but it isn't permanent feature (usually). There are some cultivars were 8 or more petals regularrly appear, but again - only on well grown large corms.

This sort of phenomenon - the multiplication of elements - is quite common in flowers with radial (rotational)  symmetry & seems to be a consequence of some kind of disturbance during development. It also occurs in animals with the same kind of symmetry e.g., starfish. Those interested may like to track down the old book by William Bateson, Materials for the Study of Variation which gives many examples of this & related phenomena. Although the book was first published in 1894, there is a modern reprint.

I have two crocus in flower at the moment, the first I think may be C. cartwrightianus, at least I did get this from somewhere, but don't know source, the second I'm really not sure about.  Any help will be much appreciated.

Hello Chris
You are probably right about the first one, it does look like C cartwrightianus.  Whatever it is, it is flowering well!
The second is definitely Crocus goulimyi.

[ChrisB]

Thanks Tony, I'll put labels in now so I know in future.  The C. cartwrightianus clump has come up really well this year, much better now its in the ground rather than pots.

A couple of years ago I dropped some small corms I was re-potting and these got mixed up. I kept the labels and potted them up individually. I have a couple of labels for autumn flowering ones without foliage but I wonder whether either are correct. The labels are C cancellatus ssp lycius and ssp mazzaricus.  Does anyone have a view please?

[I.S.]

  Ian,
  This is not a C. cancellatus lycus or mazziaricus.
  It seems to me like a C. gilanicus. a pale forms.

[tonyg]

Yep - definitely Crocus gilanicus.

Colleagues, help!
This Crocus obtained 30 years ago from a collector. I ordered Crocus speciosus, a place he sent was a little crumpled bag, illegibly signed - Crocus sp. I thought that this is the abbreviated spelling Crocus cpeciosus. Later it became clear that it is not.
Reproduces very well, gives a lot of small bulbs. Sheet is very narrow, not wider than 2-3 mm. Blooms in some years earlier Crocus speciosus, and in others later. Dates of flowering depends on summer weather.
 What a view it can be?

[Martin Baxendale]

Natalia, this is Crocus kotschyanus.

[Natalia]

 Martin, thank you very much!

Hello,

your help on the following two croci is very much appreciated.
The first I think is  biflorus melantherus.

I am very uncertain with the second, perhaps niveus.
Both should originate from the Peloponnese!
