Accurate updating of systematic information for protection and preservation of plant biodiversity can encounter many problems, both in floristics and in the context of other appropriate and useful technologies. We highlight ongoing studies on the complex genus Iris Tourn. ex L. in Italy as a case-study to stimulate researchers into providing new data for the understanding and conservation of natural biodiversity. Iris is species-rich, with 300 species and many hybrids, allowing a wide range of suitable techniques and methods, including experimental crosses. We provide examples in which dissemination of hasty, conflicting, misleading or erroneous information through the literature and inaccurate websites can be filtered and validated. Careful initial identification of the taxa and a synergistic biosystematic investigation can help to improve effective quantification and qualification of biodiversity among experts and nature lovers
