Very good plants Simon !!
The last one looks like the true species !

[Sinchets]

Thanks, Fred.

Simon,

I agree with Fred, I think that is the species I. stolonifera.  The hybrid 'Vera' has a much bluer beard and no pale areas on the stands.  I wish my 'Antiope' bloomed this year.  Slugs got the spike!   And where did you find 'Orion'?  Great looking cultivar.  I've been trying to collect the few extant Van Tubergen-Hoog clones.  Good to know this one is still around.

[Sinchets]

Thanks Jamie- I have amended my database. 
Orion came from Janis a few years ago.

[Lesley Cox]

Here is what I have as 'Vera.' Is it correct?

[Sinchets]

Out of interest Jamie, do you know the parentage of 'Orion'?

[Regelian]

Lesley,

yes, that is most definitely 'Vera'.

Simon,  unfortunately, there is no parentage noted for the cultivar.  I will ask around and see if someone may have an idea.  From the look of it, I. korolkowii is most likely one of them.  If we knew the chromsome count, that would help.

If we knew the chromsome count, that would help.

Jamie, I think you will count 21

[Regelian]

Hans,

assuming it is a primary hybrid, you are most likely correct, but it could be a cross with a korolkowi hybrid and I. hoogiana, which would explain the dark signal-like area on the falls.  Even a primary with hoogiana would give either 33 or 44 chromosomes.  No reason to discount it as a pure regelia hybrid, or do you see something there?

A wonderful form of Iris acutiloba ssp lineolata i received last year from a scandinavian grower, - I was surprised when I noted the bud a few days ago and even more when I saw the flower today - it is a  fine small/dwarf form with very dark standards- so I want thank here the giver very much again for this stunning plant!

WONDERFULL hans 
Stunning small plant !!!This dwarf froms are allways very nice with their big flowers !!
Thank's for sharing hans, but when will your Onco stop flowering ?

[Hans A.]

Jamie, as I remember most of the older Tubergen Cultivars were primary hybrids and he mostly used Iris korolkowi (22 Chromosomes) with an Onco (20 Chromosomes) - not knowing the correct parentage in my opinion it could be for example  I.k + I.iberica elegantissima (similar "Dardanus") but i do not know it exactly-  Elm Jensen studied this complex very well - do not think this is a pure Regeliahybrid.

It is not the last one...
