Morphometric study of the genus Erysimum L. (Brassicaceae) in Shomali, Razavi and Jonoubi Khorasan provinces (original) (raw)

Taxonomy and Biosystematics, 2012

Abstract

According to the "Flora Iranica", the genus Erysimum has 26 species in Iran among which 11 species are reported in Shomali, Razavi and Jonoubi Khorasan provinces as yet. In this study, two of the species ate introduced for the first time. Due to the extreme similarities and the wide variation of the morphological characters, identification of these species is very difficult. In this study, we attempted to separate the species using morphological characters. We scored 75 morphological (vegetative and generative) characters of 84 individuals belonging to 11 species. The results of the multivariate analysis indicated the separation among the studied species and showed three distinct groups among samples. The first group was individuals of E. repandum, E. griffithianum, E. sisymbrioides, E. nanum and E. persepolitanum. The second group included individuals of E. aitchisonii, E. kerbabaevii and E. crassipes. The third group consisted of E. crassicaule, E. stocksianum, E. crassicaule (with trichome) and E. ischnostylum. Finally, an identification key was introduced based on morphological characters for Erysimum species in Khorasan.
