Seven New Species of Onosma L. (Boraginaceae) with emphasis on their habitats in Iran
摘要
In this paper, seven new species of Onosma are described and illustrated. Besides, a diagnostic key is provided for new species. Hence, based on a wide range of the assessments conducted, the mentioned samples are considered as distinct species when compared with the previously introduced species in the region. Thus, it strengthens our justification as to whether they are new species. Our argument for mentioned novelties is significant differences in the most important morphological and micro-morphological characteristics following trichome type, shape and size of cauline and basal leaves, shape and size of calyx, annulus hairs, shape and size of corolla, nutlets morphology, anther length as well connection and their exertion as well pollen type and size compared to their nearest species. Besides, the recent novelties are confirmed by obviously ecological differentiations.
