Checklist for Iridaceae Family and its Geographical Distribution in Iraq

A total of 300 samples of the National Herbarium (BAG), Baghdad University Herbarium (BUH) and field survey were collected as (22) species of (5) genus belonging to Iridaceae family were distinguished. A distribution maps have been created to illustrate species abundance as it was observed that Iris species were distributed in different regions of Iraq , since Iris aucheri and Iris persica have been dispersed in the northern districts of Iraq in -MAM-MSU-MRO-districts in addition to Iris persica showed prevalence in -FUJ-district too. On the other hand, Iris postii has been scattered in west of middle and south districts of Iraq in DWD-FUJ-DLJ districts, while Iris reticulata has been distributed in DWD-MRO-MAM-districts. The dispersal of Iris pallida is limited in LEA district, Iris germanica in MSU-district and Iris xiphium in LCA district, moreover, Iris sisrynichium is found in most of Iraqi districts as FPF-FKI-DLJ-DGA-FAR-FNI-LCA-LEA-DWD-DSD-FUJ-LSM-MRO-MAM-M. The rare species Iris bakeriana distributed in -MRO- district besides Iris maculata have been distributed in –FUJ- district. An unidentifiable Iris has been observed in different districts of Iraq in –FAR- LCA-LEA-DWD-DSD-MRO-FUJ-MAM-MSU-districts. Gladiolus atroviolaceuos has been distributed in the north of Iraq in -MAM-MJS-FUJ-districts, while Gladiolus kotschyanus has been distributed in -FPF-FUJ-FAR-MRO-districts, in addition to Gladiolus italicus which has been distributed in -MJS-FPF-FKI-districts.Crocus concellatus has been observed in the north of Iraq in -MAM-MSU-MRO-MJS-FAR-FPF-districts, while the distribution of Crocus biflorus is limited in -MAM-district, Crocus sativus in -FUJ-district and Crocus pallasii in -MRO- district. An unidentifiable Crocus were observed in miscellaneous districts of Iraq in -LEA-FAR-FKI-districts.Moraea sisyrinchium has wide diversity in most districts of Iraq (DLJ-FKI-FPF-DGA-FAR-MJS-FNI-LBA-LCA-DJA-LEA-DWD-DSD-MRO-MAM-MSU-FUJ-LSM). On the contrast, the Freesia hybrida richness is poor in southern districts. Also, It has been found that Iridaceae family can inhabit wide range of soils from sandy to gravy type specially in mountain regions.
