“…persica taxonomic status in Lebanon is still debated. In fact, Hall & Seisums [ 58 ] considered some Iris persica populations of Lebanon and Syria as a new species called Iris wallisiae . They contradicted Mouterde (1966) who included I .…”

Unlocking the Karyological and Cytogenetic Diversity of Iris from Lebanon: Oncocyclus Section Shows a Distinctive Profile and Relative Stasis during Its Continental Radiation

Despite being an important target of conservation concern and horticultural interest, Lebanese irises yet have a confusing taxonomic history and species’ delimitation is often considered problematic, more especially among royal irises (Iris section Oncocyclus). Indeed, these irises of exceptionally large and spectacular flowers have radiated across Caucasus and eastern Mediterranean giving rise to a number of strict endemic taxa, many of them being considered under threat. Whilst efforts have mostly focused on clarifying the evolutionary relationships in the group based on morphological and molecular data, karyological and cytogenetic characters have been comparatively overlooked. In this study, we established for the first time the physical mapping of 35S rDNA loci and heterochromatin, and obtained karyo-morphological data for ten Lebanese Iris species belonging to four sections (Iris, Limniris, Oncocyclus and Scorpiris). Our results evidenced distinctive genomic profiles for each one of the sections, where Oncocyclus irises, while having the lowest chromosome numbers, exhibit both the highest number of 35S loci and CMA3+ sites. The continental radiation of royal irises has been accompanied by a relative karyological and cytogenetic stasis, even though some changes were observed regarding karyotype formula and asymmetry indexes. In addition to that, our results enabled taxonomic differentiation between I. germanica and I. mesopotamica–two taxa currently considered as synonyms–and highlighted the need for further studies on populations of I. persica and I. wallasiae in the Eastern Mediterranean Region.

“…That is why; Gaziantep and Amasya samples of I. persica may be the variant forms or subspecies of same species. Since some differences in the chromosome numbers of I. persica populations in Lebanon and Syria were found by Hall and Seisums, taxonomic status of I. persica is still controversial (Hall & Seisums, ). The chromosome number of I. persica populations in Syria and Turkey were reported as 2n = 22 and 2n = 20 by Hall and Seisums () and Koçyiğit et al () respectively.…”

“…Previous studies show that some subgenus has broadest aerial species ( I. persica ) that shows many variations in the morphology (in perigon color ve spatha), anatomical, ecological, caryological, and palynological characteristics (Güner & Peşmen, ; Hall & Seisums, ; Kandemir, Çelik, & Sürücü, ; Koçyiğit, Erken, Özhatay, & Kaya, ). However, I. galatica Siehe and I. persica are separated from each other with the size and structure of the bracts, colors of flowers and phytogeographical distribution.…”

Iris L. is one of the important genus of family Iridaceae, consist of 56 taxa naturally occurred in Turkey. The similarities and variations in the subgenus overlapping the taxonomic positions of the species in the subgenera and needs anatomical assessment especially by microscopic techniques. In this study, the taxonomic significance of leaf anatomical characters of 10 Iris subgenus Scorpiris taxa were studied in detail and the relationship among these taxa were evaluated using microscopy techniques. Fresh leaf samples of species were fixed in 70% alcohol solution for anatomical observation under microscope. Eleven different micromorphological features were statistically analyzed to delimit the species in subgenus. Based on morphological and anatomical similarities, we studied relationships among; (1) ssp. turcica, ssp. caucasica, I. nezahatiae and I. pseudocaucasica; (2) correlation between ssp. turcica and ssp. caucasica; (3) association of I. galatica, I. persica, ssp. margaretiae and ssp. stenophylla with each other; (4) relationship between ssp. stenophylla and ssp. margaretiae; and (5) relevance between I. aucheri and I. peshmeniana. Moreover, the taxonomy of subgenus Scorpiris has been discussed in detail with novel and diagnostic features based on micromorphological physiognomies. We found that four species in this study are endemic to Turkey, while seven are critically endangered geophytes in the country. The leaf anatomical characteristics of 10 taxa were divided into three groups. Main aim of this research was to study the taxonomy of the complex subgenus Scorpiris through microscopic techniques.

The chromosome numbers and karyotypes of five species of the genus Iris distributed in Turkey were analyzed. These taxa are I. aucheri (Baker) Sealy, I. reticulata var. reticulata M. Bieb., I. persica L., I. peshmeniana Güner & T. Hall, I. sarii Schott ex Baker. Two of them (I. sari and I. peshmeniana) are endemic in Turkey. The chromosome numbers of studied taxa were determeined as 2n=18 (I. persica), 2n=20 (I. sari), 2n=24 (I. peshmeniana and I. aucheri), and 2n=36 (I. reticulata var. reticulata). Haploid chromosome lengths varied from 53.45 µm (I. persica) to 130.78 µm (I. reticulata var. reticulata) among species. Karyotype analysis indicated that Iris taxa generally have median (m), submedian (sm), and subterminal (st) chromosomes. In addition, only I. sari has two terminal (T) chromosome pairs. The karyotype of I. peshmeniana was determined for the first time.
