Iris 2023

Hi Luc, whether I. rosenbachiana or I. nicolai it's a beautiful thing!   The distinctive notched tips to the falls are interesting and not something I've seen before in this 'complex'.  I wonder if these notches are just a seasonal aberration or a permanent feature?  The overall colouring is unusual too and perhaps this might suggest a plant of hybrid origin - does it produce a good pollen load?  Presumably Jan didn't provide detailed collection notes.  Looking at the photographs on his website there doesn't appear to be a clear distinction between nicolai and rosenbachiana and quite a few of his rosenbachianas are probably what we know as I. popovii.   The one very distinct species belonging to this complex portrayed on Jan's website is I. baldschuanica - if indeed it is that species!   I'll try and find out some more and get back to you.  Tim

Maybe this paper could help ?

At least, for me, it really helps knowing a bit better all these marvelous irises

Rosenbachiana and nicolai is all about colour of the background and for me not something to differentiate plants. The plants are not hybrids as you mention.

Once again the compact form of Iris bucharica from Afghanistan

The first of my Iris kuschakewiczii

RE COMPACT FORM OF IRIS BUCHARICA FROM AFGHANISTAN. A paper was published this time last year "Iris bucharica (Iridaceae): A century of confusion is resolved with the description of I. chrysopetala, a new species from southern Central Asia"  (Alexander N. Sennikov, Furkat O. Khassanov & Sardor O. Pulatov) which is free to download online.  The wholly yellow form has now been described as Iris chrysopetala and the traditional white and yellow 'form' is retained as I. bucharica. The main differences are colour and colour arrangement and that the lamina (blade) of the yellow species is narrowly elliptic whearas in the white and yellow species it is broadly elliptic, additionally with I. chrysopetala the blade is gradually expanded from the claw (haft) whereas with I. bucharica it is abruptly expanded from the haft.  There are other differences too.  It looks like your lovely compact clone from Afghanistan is I. chrysopetala.

Thank you for the text and comment.
My plant seems to be this chrysopetala when I read the paper.
