“…Irises produce showy flowers and are well-known and popular ornamental plants worldwide. To gain more cultivars for gardens, many crosses between Iris species have been attempted and achieved success by artificial hybridization ( Hu and Xiao 2012 ; Yu et al 2017 ). Natural hybrids between sibling species do occur in the genus Iris , for example in some species within subgen.…”

A newly discovered natural hybrid, Iris × ampliflora Y.E. Xiao, F.Y. Yu & X.F. Chen (Iridaceae: subgenus Limniris section Lophiris) from Chongqing, China, is described and illustrated. This hybrid is morphologically similar to I. japonica Thunb. and I. wattii Baker, but can be distinguished by its giant leaves and large purple flowers. Phylogenetic trees based on cpDNA data support the separation of I. × ampliflora from other closely related species in the section Lophiris. According to its morphological features, molecular systematic evidence and chromosome data, we speculate that I. × ampliflora [31 chromosomes] likely is a new hybrid between I. japonica [2n = 32] and I. wattii [2n = 30].

“…In general, the plants of non‐hybrid species of Phaeiris are clearly not asexual, even if asexual reproduction is common within some hybrids of Phaeiris (e.g., Burke et al 2000) and already Small (1930 b ) and Viosca (1935) have mentioned some issues with the seed reproduction of the Floridian and Louisianan blue flags. In general, apomixis is not common in Iridaceae, reported as far as we know only for Belamcanda chinensis (Yu et al 2017).…”

On biodiversity and conservation of the Iris hexagona complex (Phaeiris, Iridaceae)

et al. 2021

Taxonomic revisions using newly available molecular data can have profound consequences for identifying areas of high endemism and, therefore, high conservation priority. A good example of the connection between taxonomy, biodiversity ecology, and conservation issues is genus Phaeiris (Iris subsect. Hexagonae), an endemic taxon of the southeastern United States and in particular P. hexagona (I. hexagona) (Blue Flag), perhaps the best-known species of this genus. Some authors recently provided evidence for the need to revise the taxonomy of the Blue Flag, which has usually been considered to consist of a single species, P. hexagona. Using molecular and bioclimatic analyses of Blue Flags from Florida and Louisiana, collected at their loci classici, we challenge the notion that P. hexagona is a single species, referring to the almost forgotten taxonomic context of Phaeiris as established by John K. Small and Edward J. Alexander nearly 90 yr ago. Our vision of the P. hexagona complex reinforces the current treatment of Southern Coastal Plain as a biodiversity hotspot. Our results also argue for the complex nature of endemism on the Florida Peninsula, and elsewhere on the Southern Coastal Plain, including a new interpretation of the well-studied Louisiana irises. We also propose that the valleys of Florida rivers and lakes are likely to harbor additional hidden biodiversity. Accurate taxonomy proved to be a heuristic tool to characterize better the actual level of biodiversity within Southern Coastal Plain as well as to describe the different areas endemism. The newly re-documented taxonomic diversity in broadly defined P. hexagona should also be considered in future conservation efforts.
