:Tom, I am sure you will forgive me for making one small correction to your
:response to Lonnie. Of the irises Lonnie mentioned, Iris germanica has
:played no role in the breeding of modern TB irises...(or any other type of
:modern iris either). Although it has been written that I. germanica sets
:pods in very warm climates, I have never seen a documented case of this that
:could be verified. For all practical purples, germanica is a sterile
:interspecies hybrid. I suspect that the cases where people have thought that
:germanica set pods were cases where the iris was something other than
:germanica.
Oh, Clarence. I *oh so deftly* skirted the issue of I. germanica, and here
you come beating the bushes! I agree with what you write, except that
Brian Mathew in _The Iris_ (and Eric Tankesley-Clarke at Adamgrove)
resurrected I. germanica to apply to a host of different bearded irises,
including the fertile tetraploid I. croatica (which always seemed to me to
be a kissin cousin of I. aphylla). So I wasn't fearless enough to spout
"Germanica is a sterile IB clone" from _The World of Irises_. I hereby
officially refuse to make any statement about what "I. germanica" is or
whether it ever crossed with anything.
