Re: Re: Iris pallida cultivars and nomenclatural question

Hi,

Guess I'll keep digging.  I mainly want to have a proper "label" to give
these hybrids.  I think the "trend" for or against names for species
hybrids varies with the group being studied.  For instance in some groups
(cactus are a good example) there are authors coining hybrid names left and
right simply because nobody has done it, and they can get lots of names
published that way (or so it seems).  These are botanically valid, but
sometimes highly confusing.  [i.e. the type specimen of Echinocereus
roetteri comes from a hybrid swarm involving five species.  It could be
genetically any combination of these five species.  However, it LOOKS like
only two, so it is traditionally used as the name for E. coccineus x E.
dasyacanthus - this could technically be incorrect].  Usually it is not
this complicated though.

In the case of the names I. squalens and I. sambucina, they are both
already validly published names, and appear to be the oldest for hybrids
such as neglecta, sambucina, flavescens, etc. etc. etc.  However, it is not
clear if priority by one over the other has ever been established by a
"first reviser".  They were named in the same publication, so neither has
priority until one is used first by a subsequent author to include both.
It seems that in all those years, somebody must have done so, but it's
difficult to find who or when.

Frustrating.

I've never seen a group of plant where taxonomy, nomenclature, and botany
of wild plants is so overshadowed by cultivar names and horticulture.
Makes it interesting too.
