Re: I. tectorum and other crested iris

Walt: on page 3693 of SIGNA the article states  ". Until this point all our groupings have been natural, related groups. But the crested Irises are an artificial group that was created out of convenience. Certainly it is easy to identify the group but it is misleading and someday will be reorganized. We know that Iris tectorum that has large crests is undoubtedly closer related to the bearded Iris. But current classification lumps the crested Irises together and is handy for learning the classes as a starting point. " 

Since the revision of this group has yet to be attempted, let alone published I presented the crested Irises as they are currently labeled in the literature. Work on chloroplast DNA at Kew will undoubtedly show a variety of affinities for the various species. I was asked to give a synopsis of the _current taxons that the beginner could understand. Since the new taxonomic breakdowns have yet to be published the above statement was all I could really do. The SIGNA checklist lists all published crosses for each species and is a summary of what will cross with what. Certainly the history documented there shows tectorum to have crossed several times with bearded iris but never with beardless or for that matter other crested Irises besides the japonica group.

I got the SIGNA magazine a couple of days ago, and thanks for an
excellent job. I edit an heirloom garden seed newsletter, so I know
how hard it can be just to get one out. To do so as well as is being
done is even harder, I'm sure.
About the artical on the taxonomy, I noted that the crested iris are
with the beardless iris, not the bearded ones. It is noted that I.
tectorum does cross with the bearded iris, and it might be moved
there in the future.
But I. tectorum crosses with some other crested iris, if my memory
serves me. So would they also be transferred? Or perhaps the
crested group is an artificial group that needs to be split?
What do those who know more than me think? This would be all of you,
so jump in and tell me.
