Species of natural hybrid origin and misinformation in the Irises: A reappraisal of the presence of I. aphylla L. in Italy
No full textThe identity and status of the records of Iris aphylla L. for Italy are reconsidered. The authors are of the opinion that I. perrieri Simonet ex N. Service, present in Savoy, France, is genetically and morphologically distinct from I. aphylla, and that the Italian populations from Piemonte are in fact conspecific with I. perrieri. In addition, we consider that another iris, I. benacensis A. Kern. ex Stapf , which occurs near Lago di Garda (Mt. Brione) and is often also regarded as a synonym of I. aphylla, is not conspecific with either I. aphylla or I. perrieri. Macro-, micro-morphological and biosystematic data obtained during this investigation suggest a possible natural hybrid origin of these species and confirm the opinion of the authors, which is justified also by the different chromosome numbers and distribution of the taxa examined. © 2008 Società Botanica Italiana
Preliminary data on percentage between species and natural and naturalised Iris hybrid taxa present in Italy.
No full textThe evolutionry activity of seed plants can be tested also by the number of species of natural hybrid origin and natural hybrids present in a family and in a genus. In our first approach to the present investigation, we started the overview of the Iridaceae family in outlines by the number of taxa tha can be derived from a natural hybridisation. In Italy, there are many doubtful Iris taxa of possible hybrid origin, that represent a source of mistaken synonyms. Our preliminary results, here shown, concern the percentage of the estimated natural hybrids of the genus Iris L. This genus, considered to be at the top of the evolutionary trends of the Iridaceae, includes the highest number of natural hybrid origin taxa belonging to this family, and this datum is confirmed by biosystematic analysis result
