Merendera is included in Colchicum but it differs by having no flower tube right?

In "merendera" elongated bases of flower segments are not joined together forming flower tube as in typical Colchicum. Now Karin Person (Gothenburg BG) joined Marendera and Bulbocodium in one Genus as Colchicum.

You are welcome Kris :)
I know them because they were a big problem for Ottoman Empire. We know them as "Rhodos Knights"

Some really super Colchicum being shown here.


Here are some notes from a friend in New Zealand, Betty Clark, about how she grows from seed and also about how she finds some species to be with her...


RE: growing Colchicum from seed.
I collect the seed  as soon as it is ready I then put in paper bag and keep at room temperature for several days.
 Now this is my treatment for all bulbs:  A shaking of  stone chips in pot then half fill with Potting Mix then fill with seed mix.  Pour over a generous amount of boiling water to cleanse then when cold plant seeds on top bringing the pot to top with very fine stone chippings.   I do not cover and they stand on shade bench until they germinate. Last year I planted in margarine containers with holes and have had thousands of seeds grow. I leave them without disturbance for another year when I repot.  Have done these for the last 30 years and as you can imagine I am getting a little long in the tooth now.  It is impossible to identify colchicum by looking at the flower only. You need a year for measuring the leaves.

The first to flower with  me is C.byzantinum, in  March.    Differs from cilicium in that the stamens are curved at ends. They are tipped with crimson dull yellow segments. Rarely sets seed.  Leaves in early spring  are 30cm long ribbed and corrugated. It come later into leaf than C. baytopiorum.                                     
C arenarium, March, Pale pink punctate rounded at tip  Segments 2cm wide 3.5long   Leaves 2 to 5 per corm Often confused with C.alpininum which has  more leaves.           
C. balansae March  Several pink  flowers per corm   Hook on top of style with pale yellow stamens.   Leaves shiny green,segments 4 to 7cm long     Very deep corms             
 C. tenori  Halfway between tesselated form of agrippinum    In shape like C.autumnale, only crimson colour of stigmatic hook which is continued a little way down style.   

Collectors No HC  1051  Henning Christanson    Faintly chequered   I have a letter confirming that he had sent bulbs to Mary Evans which I now have. I still have her collection and hope too clean a lot up this year.

See this post for first mention of HC1051......

Some more on Colchicum from Betty  Clark:

In honour of Mary Evans who challenged me to sort out the Colchicum Species.
To  those that will disagree with me I need your reasons Please just dont write me off.  For many  years I have been collecting information from all writings that I can lay my hands on.   Impossible to do by looking at the flowers you need bulb size leaf size and that takes a full year for each species.  Some flowers open with  anything in between to 3months later.           
is my first offering.
      Colchicum byzantinum                 Autumn here 11 Feb.
               10-20 pale lilac/pink flowers per corm                Very faint white stripe
                First showing white with pink tip
                Tepals rounded at apex   3-4cms by 1.6cms wide
  Styles white with pink tip   divided into 3 longer stamens,  yellow turning brown.
               
  Leaves ribbed 15cmwide by 30cms long         These do not appear until  MAY>
                   
 Corm largest              DOES NOT SET SEED 
  Probably a hybrid between C. autumnale and C.cilicium

 Differs from C cilicium, which has a bright crimson to stamens   Anthers not crooked at tip with leaves soon after flowering               

  E.A.Bowles, Patrick Synge and Byran and other journals can't be wrong.

I posted these pics to the SH thread for confirmation but thought I'd try here as well!
This came from a friend as Colchicum corsicum
272894-0

272896-1

And this one I grew from Srgc Seedex 2004 as Colchicum sibthorpii
272898-2

272900-3

What do others think?

Fermi, took those photos a minute ago , maybe they will prove to be of some help.
Colch. corsicum was grown from seed ( it sets seeds in great quantities ) sent to me by E.B. Anderson
many years ago =1965 .
 As far as I know C. sibthorpii is a synon of C. bivonae - could not find a specimen that had not been munched by snails .

Hi,

Just a few to add to Otto's autumnal offerings.

Colchicum agrippinum
Colchicum macrophyllum from Profitis Ilias on Rhodos
Colchicum byzantium - thats what I know this as. I found it growing happily around an abandoned farm house in the Victoria Valley here in Tasmania. There are 100s here all doing well and apparently given a wide birth by both livestock and macropods respectively.

Cheers, Marcus

Hi again,

A quick whip around the garden has yielded further species.

A more pristine version of C. bivonae than Otto's
Colchicum davisii
Colchicum variegatum collected as seed on Mt Ambelos, Samos
Colchicum cilicicum collected as seed with Norman Stevens south of Gulnar in amongst scads of Fritillaria persica
Colchicum laetum
Colchicum cretense collected as seed above Omolos Plain where I lost my bag with my wallet in it and the local restauranter found it with his telescope!

Cheers, Marcus
