A revision of the genus Roemeria in Iran

In this study، a taxonomic status of the genus Roemeria in Iran is reviewed. The study of morphological characters of collected and herbarium specimens led to the introducing of two new taxa، namely، R. hybrida subsp. maculata and R. refracta var. alba. In addition، five synonymies are made as following: R. refracta var. albomarginata and R. refracta subsp. occidentalis as synonymies of R. refracta var. refracta; R. hybrida subsp. dodecandra، R. latiloba، and R. hybrida var. hispidissima as synonymies of R. hybrida subsp. hybrida. The identification key and diagnosic characters of taxa and their geographical distribution are presented here.
