Hi all! Here, I put some new (I hope ;D) mutation I found recently for the genus - with completely calyx-like petals. The same for the pistil looking like a leaf. The anthers are normal as I saw, remains to determine whether the pollen is formed and whether it is fertile.
I've named this one as "CHUGUYSTER" (it is folkloric Carpathian forest spirit) ::) ::) I still imagine how it will look in mass when it forms a clump!!!
-
OOOOOO i like that ;D What a great find !
-
well spotted!
-
Nice Dimitri. 8)
Is it a new find this year or is it a find from a previous year so that you know it will always do this?
-
That is a wild-looking nivalis Dmitri and it must have been hard to spot. Well done.

John, this one is always like on picture, I know culture population from near 10-15 plants of different petal length but all of them have calyx-like flowers. It was found in some wild Ukrainian sites and still growing during 10-15 years in one live collection of some person.
-
Dmitri it is most interesting how the spathe seems to be below the 'flower' too, well spotted.
-
Yes, Brian, the spathe opens via the top!
-
great find,Dimitri !

Dimitri,
good luck and fingers crossed
very very unusual
-
Beauty is in the eye of the beholder so they say. Without doubt I would bin it.

Thanks, Hagen! Apparentely, this one hasn't the pollen at all((( only somewhat similar to anthers....

Throwing away the child with the bathwater ;D
Unbelievable beautifull Dima :o :o
-
Thanks, Gerard! I try diligently! ;D

I risk to be the dog in the manger. But...
... looking on this poor mutation reminds me the Chernobyl nuclear disaster that occurred 25 years ago on 26 April 1986... :'( :'( :'(
I'm sorry.

PHYTOPLASMOS - phyllody-like snowdrop enigma is resolved :-[ :-[ :'( I DO think the mentioned below is actual to all spiky-type or green-petal snowdrop cultivars (also to Tulips and Trilliums), so, please, be carefull with them - it is transmissible disease!
Symptoms (c) from Wikipedia
http://en.wikipedia.org/wiki/Phytoplasma
"A common symptom caused by phytoplasma infection is phyllody, the production of leaf-like structures in place of flowers. Evidence suggests that the phytoplasma downregulates a gene involved in petal formation (AP3 and its orthologues) and genes involved in the maintenance of the apical meristem (Wus and CLV1). Other symptoms, such as the yellowing of leaves, are thought to be caused by the phytoplasma's presence in the phloem, affecting its function and changing the transport of carbohydrates.
Phytoplasma infected plants may also suffer from virescence, the development of green flowers due to the loss of pigment in the petal cells. Sometimes sterility of the flowers is also seen.
Many phytoplasma infected plants gain a bushy or witch's broom appearance due to changes in normal growth patterns caused by the infection. Most plants show apical dominance, but phytoplasma infection can cause the proliferation of auxiliary (side) shoots and an increase in size of the internodes. Such symptoms are actually useful in the commercial production of poinsettia. The infection produces more axillary shoots, which enables production of poinsettia plants that have more than one flower.
Transmission/Movement between plants
The phytoplasmas are mainly spread by insects of the families Cicadellidea (leafhoppers), Fulgoridea (planthoppers) and Psyllidae (jumping plant lice), which feed on the phloem tissues of infected plants, picking up the phytoplasmas and transmitting them to the next plant they feed on. For this reason the host range of phytoplasmas is strongly dependent upon its insect vector. Phytoplasmas contain a major antigenic protein that makes up the majority of their cell surface proteins. This protein has been shown to interact with insect microfilament complexes and is believed to be the determining factor in insect-phytoplasma interaction. Phytoplasmas may overwinter in insect vectors or perennial plants. Phytoplasmas can have varying effects on their insect hosts; examples of both reduced and increased fitness have been seen.
Phytoplasmas enter the insect's body through the stylet, move through the intestine, and are then absorbed into the haemolymph. From here they proceed to colonise the salivary glands, a process that can take up to three weeks. Once established, phytoplasmas will be found in most major organs of an infected insect host. The time between being taken up by the insect and reaching an infectious titre in the salivary glands is called the latency period. Phytoplasmas can also be spread via dodders cascutaceae or vegetative propagation such as the grafting of a piece of infected plant onto a healthy plant.
Movement within plants
Phytoplasmas are able to move within the phloem from source to sink, and they are able to pass through sieve tube elements. But since they spread more slowly than solutes, for this and other reasons, movement by passive translocation is not supported ".
So, bye-bye, my lovely Chugayster - you're terminally incurable and contagious...... :'(
-
How sad :'(
-
There is a god after all.
-
Dima,
You have thrown it away? :'(
-
Dima,
You have thrown it away? :'(
Yeep :-\
-
At what time they do collect, please get it out of the bin i can cure it! :o

Gerard! THIS ONE GUY is fully incurable!!! :'( it is bacterial disease that could spread and infect all other your drops then they all will become similar to this one))) you could see the same phytoplasmos on fall-blooming Colchicum umbrosum from Crimea pictured this spring (defective flowering in spring!) in Crimea by Vladimir Savchuk.
-
Just boiling the bulbs for 2 1/2 hour at a steady 42,5 'celsius and a 0,5% formaline solution. After boiling the bulbs treat them with SiO2 desinfection and SiO2 universel!
It works very well against bacterial diseases!
Its a pity you have thrown it away, i could have cured it but it would probably not have shown the same flower next year :'( :'(
-
But Gerard, if the "cure" for bacterial infections worked, then of course the flower would not be the same, because it was diseased inthe first place!
There are mopre than enough plant diseases going around without encouraging more inthe shape of deformed specimens, surely, even for the galanthophiles? :o ::) :-X :-\
-
Does this mean the likes of 'Blewbury Tart' are similarly infected?

We would have known if i had had the chance. Lots of plants/bulbs are infected with several diseases/virus Maggi! Those who know it from we dont want to get it out because it loses its special colour/combination or shape.
-

No, Anthony, I hardly believe Blewbury Tart could be infected with phytoplasma, it is just double form, BUT who knows? Any case the precise analysis must be done, like PCR and cytostaining of infected plant organ cross-sections.....
-
Gerard ;D
it would be great to enjoy such "special color", if these infected plants wouldn't be the potential source of contamination for other healthy plants via insect vectors..... :-[ making all infected plants similar like these ones drop and colchicum on pictures above...
