Additional Contributions To Taxonomy, Nomenclature And Biogeography Of The Turkish Crataegus (Rosaceae) Taxa

Crataegusazarolus L. has a wide distribution pattern from the western Mediterranean coasts to the eastern parts of Iran with several varieties adapted to local climatic conditions. Crataegusazarolusvar.senobaaensisvar. nov. is described as a new variety from southeast Turkey with characteristic deep leaf sinuses, mostly 3–4 pairs of lobes and leaves ovate-oblong in outline. Two varieties of the species are accepted under the name of Crataegusazarolus and the correct names are published here. CrataegusmonogynaJacq.var.odemisiivar. nov. is described from İzmir, in the western part of Turkey. This new variety is distinguished by its orange fruit colour. An outstanding disjunct distribution pattern has been discovered for the recently described species, Crataegusyaltirikii Dönmez. Updated descriptions and infraspecific identification keys for Crataegusazarolus and Crataegusmonogyna are given and pictures and distribution data for the new taxa are also supplied.PubMedWoSScopu
