There are about 30–40 species of Iris
in Italy, some of these are native wild species, some are widespread across Europe with an unknown native range, some are hypothesized as natural hybrids that have persisted and given species status, and the taxonomic status of some is unknown with some authors considering them synonyms of other species. Our focus for this trip is subgenus Iris
and our plans included travel to four areas that were likely to have species of interest.
I. pallida subsp. pallida
I. pallida subsp. cengialti
Four species, I. albicans I. germanica, I. sambucina, and I. variegata, not considered native to Italy and/or that lack wild populations also occur here and may be encountered.
