Re: SPEC: I.lactea

If you really want to avoid the snow, come to Oz. It'll be 37oC (100oF)

Subject: [iris-talk] SPEC: I.lactea

> A recent talk at the Ottawa Valley Rock Garden Society included a slide
> of Iris sintenisii form a garden in Ithaca which appeared to me to be a
> good example of I.lactea.  In re-examining this issue, I noticed that
> lactea seems to come in a wide range of colour forms.  Are they all
> lactea?
> Starting with the illustration in Waddick and Zhao, despite the very
> small picture, we see a flower which is reddish violet with a white
> veined fall and violet edge.  This flower is very similar to the larger
> photo in Glasgow on p. 77.  But what about the lactea that is
> illustrated in the latest NARGS Bulletin on p. 272?  Completely white
> falls and the colour of the standards and styles is blue rather than
> purple.
> Mathew [p.125] covers all bases by saying that the "flowers are blue,
> bluish-violet or purple, the falls usually with a paler, whitish or
> yellowish dark-veined haft.  White forms occur in mixed populations with
> the blue...".  BIS goes right off the scale claiming that the flowers
> are "creamy-white" and offering no violet or other colours as an
> alternative [p.202]. Kohlein broadens the situation further with
> reference to flowers of "whitish ones with darker veins, pale blue ones,
> cream colored, and also rich violet ones"[p.157].
> Finally, I have a screen saver which is a field photograph of a flower
> that looks like the Waddick lactea but is identified as ruthenica from
> the Altai Mountains
> [http://pisum.bionet.nsc.ru/kosterin/index.htm]. [I would note that this
> is an excellent source of photographs of Central Asia plants and
> butterflies in the wild]
> It is obvious that lactea is very variable but can anyone tell me
> whether the NARGS plant is lactea and the Altai "ruthenica" is really
> lactea.
> Just thoughts for Christmas!
