Abstract

The area that has been studied is a part of northern plain regions with 86 hectares area in the east of NOOR city. It is located between Mahmoud Abad and Nowshahr. Its geographical position is 51o 46' N and 36o 47'. In this study 110 species were collected which belong to 40 families and 93 genus. Of the species recognized 21 species (% 19.1) are endemic of IRAN. Gramineae with 22 species (%20), Composite with 11 species. (% 10), Legominosae with 9 species (% 8.8) and both of Cyperaceaand Labiatae with 6 species (%5.45) are the main families of this area. Studying plant LIFE FORM by Raunkiaar method showed that Hemicryptophytes with 47.27 percent (52 species) of species are the most frequent plant forms. Cryptophytes and therophytes occupy %22.73 and %21.82 of the area's FLORA respectively. High percentage of Hemicryptophytes indicates that the area has moist-temperate climate with cool summer and higher rainfall. Investigation on geographical distribution (chorology) of plants indicated that %27.27 (30 species) of the FLORA belong to IRAN-Touranian zone and % 19.1 (21 species) of the species belong to Europe-Siberian zone and other species can be also observed in other zones. High percentage oflran-Touranian elements can prove that this region belongs to IRAN-Touranian zone.
