Re: Seedling Iris tectorum hybrid

Thanks for the photos. Certainly look like a hybrid.

I don't consider the purple at the base as PBF. This is a different 
condition, I call it purple rhizome (perhaps someone has a different 
term that has been used). This is seperate from PBF which is on the 
leaves and usually several inches of the leaf.  There are a lot of 
smaller iris (SDB, MDB etc.) with this colouration in various 
intensities.  I started to record this at one time and also classified 
some as having both purple rhizome and PBF.  PBF is only on leaves 
where exposed to sun, purple rhizome is most pronounced  under leaves 
and not reduced by absence of sun. If you do an epidermal peel of PBF 
you find it only in the epidermis.

Subject: [iris-photos] Seedling Iris tectorum hybrid

   Here are photos of the seedling I posted about at
 Iris-Talk and Iris-Species-Forum. The first image
 shows the pleated foliage typical of Iris tectorum --
 although it's atypically tall and narrow. The second
 image shows a close-up of the leaf bases (at the
 rhizome) where a little bit of PBF (purple based
 foliage) is now showing. I've never seen PBF on any
 Iris tectorum, so I'm encouraged that this is really
 the intended hybrid: Iris tectorum alba X bearded
 diploid (Iris pallida 'Kupari' X Iris variegata).

 Has anyone ever seen this purple pigment at the leaf
 bases of any clones of Iris tectorum?
