Saluk National Park is located in Northern Khorassan province, NW Esfarayen between 37˚ 07΄- 37˚ 14΄ N and 57˚ 10΄- 57˚ 17΄ E. A total of 1137 plant specimens during 2007–2009 were collected and 505 taxa (species, subspecies and varieties), belonging to 296 genera and 71 families were identified. The largest families in the area are Asteraceae (80 taxa), Poaceae (46 taxa), Fabaceae (45 taxa) and Brassicaceae (42 taxa) respectively. The most diverse genera include Astragalus (25 species), Cousinia (12 species), Allium and Alyssum (each with seven species) and Veronica (six species) respectively. The life form rates of the taxa were as follows: Hemichryptophyte (36.7%), Therophyte (34.4%), Chamaephyte (11.3%), Geophyte (9.7%) and Phanerophyte (7.9%). From the standpoint of vegetation type, 56.2% of the chorotypes belong to Irano-Turanian vegetative elements. The results show that 31 taxa (6.1%) are endemics and 36 taxa (7.1 %) exist in the IUCN list. During this reaserch one species “Senecio joharchii (Asteraceae: Senecioneae)” is presented as new species to science and three species are recorded for the first time from Iran.
