I find the current thread about *I. germanica* a
bit puzzling. I've been under the understanding that *I. germanica* (the
"real" one) was/is neither more nor less than a specific clone of a
44-chromosome hybrid mistakenly identified by Carl von Linne' (or one of the
other variant spellings of his name) as a species, and, unfortunately, on which
he based the herbarium specimen as *the* type for the entire genus
Iris. All other species are described by how they compare or differ from
this particular speciment of a particular clone in official taxonomic
literature.
Confusion is greatly increased when arboretum
speciments are labeled "Iris germanica" with a cultivar name following, as if
the cv were a named form of that "species" which doesn't actually
exist.
Further, Wal-Mart and such often have their
packages labeled "German Iris" with a clone name (usually incorrect) for the
contents.
I have never heard kochii, albicans or any other of
the 44-chromosome hybrids of the same type as *germanica* referred to as
variants of that non-existent "species." The "species" *germanica* refers
only to a particular herbarium specimen and living members of the same
clone.
The origins of these 44-chromosome hybrids are
from either unreduced gametes of the diploid European hybrid swarm of *pallida,*
*variegata* and the various balkan species OR the Asiatic tetraploids, some of
which can be found north of the Mediterranean, crossed with what used to be
called *chamaeiris.*
I'm not positive what the species designation of
that complex of not-necessarily identical specimens collected in the wild north
of the mediterranean will finally reign. It won't be *chamaeiris,* for
sure, and may or may not be *lutescens.* I thought I remembered
*olbiensis* used in some texts. The book on that one closes when the dust
settles, and I'm not sure it has even begun settling yet. The species
complex, itself (themselves?) appear to be amphidiploid hybrid(s) in
nature as well, involving one of the n=8 dwarfs, *pseudopumila* if I remember
rightly, and one or more n=12 European species. Since yellow
pigments are common, it may be that *variegata* is involved somehow. The
depth of color of kochii among others suggests something more than *pallida* and
*variegata* in the mix--probably some form or kin of *aphylla* mixed in there
somewhere, even though the flower sizes and heights suggest
otherwise.
