Sternbergia 2008

[Maggi Young]

I hadn't actually thought of it in those terms, Ashley.... but now you mention it.....

[Gerry Webster]

Here is the key to Sternbergia from the CITESBulbChecklist (1999). While it will not settle every questionable identity, it might help. Call the rest hybrids (if you are a splitter) or intermediates (if you are a lumper).

Gerry, I have amended your post to show the key full size... I have also printed it off!
Cheers,

Sternbergia pics from me again ( we have sun )  :

Sternbergia greuteriana Alan Edwards form
Sternbergia lutea ( from the Kyklades )

[Gerdk]

Hi Hans,
It seems both are the 'real ones' - especially the flat leaves of Sternbergia lutea without a central glaucous stripe correspond the key from Kamari and Artelari!
Fine plants indeed!

Gerd

[Hans J]

Yes- Gerd 

I believe too that this both are correct named .

Know maybe anybody from where this Alan Edwards form is collect ?

Sternbergia greuteriana Alan Edwards form

Hans  - have you compared this plant with the unidentified plant from Alan Edwards which Art posted on Sept 03 (reply 30)?
What do you think?

[Hans J]

Gerry ,

I had also this idea ...but I think my plants are different !
If you look the petals of the plant from Art are broader ...and his plant has longer flowerstalks and more flowers per stem ....and also my plants are much later .....

[Hans J]

Hi all ,

here is again a pic from this
Sternbergia greuteriana  Alan Edwards form - now with measure ....the leaves and petals are really narrow !

How to print off the Sternbergia key........ I may have  right-clicked on the text and selected "print picture"...... that certainly works

I agree Hans, they do seem to be different.
I think Alan Edwards collected in both Greece & Crete.

Maggi, I thought it being useful to copy the doc. in Word, which is easier to pick lines out or print.
Here it is and if not appropriate you may delete this posting.

If you use a Mac you can click on it & drag it to the desktop (or elsewhere) as you would with a picture. Then deal with it as you wish.
