Abstract
A revision was carried out on the genus Lappula Moench (Boraginaceae) in Khorassan provinces. A total of herbarium specimens collected from different parts of the studied area, including the three provinces of North, Razavi and South Khorassan, were studied. All specimens are deposited in Ferdowsi University of Mashhad Herbarium, (FUMH). According to the results of the study, there are 6 Lappula species in the region: L. barbata, L. microcarpa, L. semiglabra, L. sessiliflora, L. sinaica and L. spinocarpos. In addition, by revising the annual specimens that had been previously misidentified as L. drobovii, a perennial species, these specimens were identified as L. sessiliflora. Identification key, distribution map and species pictures in this article have been presented.

Abstract
During the study on the specimens of Astragalus sect. Ammodendron in the herbarium of Ferdowsi University of Mashhad (FUMH), based on the last and most recent sources, two new species, i.e. A. microfoliolatus sp. nova and A. rashed-mohasseli sp. nova were found and described. Morphological evidence confirmed that the belonging of these taxa to Astragalus sect. Ammodendron. The most important differences between A. microfoliolatus and its closest relatives are leaflets with very small size and glabrescent legume. Also, the main distinctive characters ofA. rashed-mohasseli are the presence of hairs on the dorsal side of vexillum, oblong legume and short rachis. Hairy vexillum has been obseverd for the first time in this section. In addition, A. aiwadzhi is recorded as a new species for the flora of Iran.

Abstract
The Palang Galoun protected region, comprising 34935 hectares, is located 75 km northwest of Najaf Abad, and 102 km northwest of Isfahan city. The aim of this research was to assess the floristic spectrum, life form varieties, chorological analysis, determination of protected status and identification of medicinal, threatened species criteria and poisonous plants of this natural heritage. Plant samples were collected during different vegetative seasons at several stages. Life forms of samples were determined and chorological analysis was performed. On the basis of the obtained results, a total of 166 species belonging to 126 genera and 39 families were identified. Six families, 23 genera and 26 species belonged to monocotyledons, whereas 33 families, 103 genera and 140 species belonged to dicotyledons. In terms of chorological analysis, 58% of plant species were distributed in the Irano-Turanian region. It is noteworthy that 44 endemic species, 97 medicinal species, 48 pasture species and 23 poisonous species were present in the studied area. Life forms were found to comprise 54% hemicryptophytes, 24% therophytes, 10% geophytes, 7% chamaephytes and 5% phanerophytes. Based on IUCN red list categories and criteria, there were 22 species in the lower risk category and seven species categorized as vulnerable case.
