Crocus November 2012

[Hans A.]

Some pics from yesterday in my garden - thanks to very generous friends two exceptional beauties are flowering on the Balearic Islands:
Crocus hyemalis - looks every year better  - and also Crocus moabiticus has adapted well the last years to the local conditions, it is the first time it has a fascinating flower.
As the control of moisture in pots is quite difficult with such delicate and rare plants I planted them out (accompanied by
 some heavy bellyache) - it seems the decision was not wrong.

Hans, nice clump of C. hyemalis, but C. moabiticus is gorgeous!

Can anyone shed any light on this 'new'    species please?

Lots of rain today, but in the afternoon some blue sky was visible with a trace of sun. Not the best conditions for opening up its flower, but one lilac Crocus mathewii decided to do it (a little bit) making me very happy .

White on the outside, but lilac on the inside.

Thanks Poul!

Nice Crocus John, but some details of your mathewii are strange:

- no stamens are visible
- long leaves at flowering time
- very late flowering

This details remember me my mathewii-imposter I received some years ago - it was a hybrid of somthing else but mathewii.

CROCUS DEMIRIZIANUS - it is very close to C. nubigena. It is described from surroundings of Čan - from roadside to Čannakale. There are mentioned three features separating it from nubigena. One of them relates to leaves but by my opinion it too much overlaps with nubigena. Another two seem to be more valid. The first is colour of petals - in demirizianus it is white with bluish purple flushed outside, in nubigena it generally is striped. How valid it is? I don’t know. Many species from biflorus group has specimens growing side by side with flushed, speckled and striped back of petals. Such B. Mathew mention for C. nubigena, too. The third feature is shape of anthers. In demirizianus it is pointed. You can compare this on attached pictures.
I have sample (R2CV-008) from almost same locality, only collected a little higher (demirizianus ~360m, mine 435 m). Another stock from lower altitudes didn’t bloom with me yet (I have only 2 years old seedlings from wild collected seeds). May be Ibrahim has pictures of this one.

Sorry, I didn't know how to inserrt picture from PDF file. So the last entry in attachment files you can open using Microsoft Word Document program. May be Maggi can place it as picture. It is fragment from picture in original publication.
Picture added to your post now Janis

Thank you Janis.

  I was realy  surprised when I see this Nourdic Journa  because I have found this crocus 3 years ago. Just it was waiting for research on it.
I have seen first time this crocus with seeds pots on at the end of february at att. 250m. I was very happy that I have discovered an autumn biflorus. Next year they start to flower in december and finished january so It can't be an autumn crocus but early one.
  According to my own opservation this is very close to nubigena by morphologie and geography. I can only separate this from nubigena by its long filaments and without any regular strips on outer petals.
  You can find some more photos im my own blog wich I just started to build up,

Many thanks for fantastic pictures, Ibrahim. Your website is very good, too. Pictures of "demirizianus" confirms variability of petals outside colouring. I checked my nubigena pictures and found that tips of anthers are very variable  -  pointed, rounded and filament's length varie, too. Plants from Samos has blue flowers (only few bloomed with me yet). So it seems that only early blooming allows to separate it from nubigena, but for such altitude it isn't special. So I don't know how valid as species it is. Most likely I would keep it under label Crocus nubigena - at least my plants.

That's what i like to hear.Janis you have made me happy.

Ibrahim, marvelous photos on your blog site.   I notice your link to the SRGC still uses the 'old' link, may I ask you to change that to  www.srgc.net   ?
I've added a link to your pages from the SRGC links.
Thank you! 

What a very beautiful crocus this " demirizianus "is ....

[Janis Ruksans]

Not the season, but I want to add here pictures of some of mine nubigena, mostly from Lesbos and Samos.

 Maggi  thank you so much  for nice compliments. I just start to make my blog so update whenever I learned to use the program.  It will take lots of time but no problem I have time..

Janis you are right C. demirizianus and C. nubigena also is very variable.  For C. demirizianus early flowering is my observation. Where I have seen this plant was low altitude only 250 m.  Maybe they found it higher part! If so It can flower later too.  My  another observation on this crocus, It was a small in size almost half size of nubigena. Bunt in my samples most important feature is long filament.

I am attaching couple pictures with arrow shape of anthers  and variations of petals.
With my best wishes to all croconuts….

Hans,

Thanks for replying. I have noticed the difference with other mathewii too this afternoon when looking at it more closer. And looking at your 'Dream Dancer' photo on the link you have given, it  pretty much look the same as mine. So an imposter it is than? Have you tried to pollinate it. I couldn't find any good anthers on mine. White and shriveled. I obtained mine as 'Dream Dancer' too by the way.
