An investigation of the flora of Fayabregion of kahnog city inKerman province

In this study, the flora of theFaryab region, in 76 Km of the kahnug city in South of kerman province investigated. This region is a mountainous area with some small plains and short hills that cover a surface of ca. 16000 hectares. The annual precipitation in the region is about 180mm and its elevation varies from 636 to 1196 meter above of the sea level (mean is 916 m). The results showed that there were 186 plant species belonging to 135 genera and 43families of higher vascular plants (40 families were dicotyledones, 3 families were monocotyledons, The family Asteraceae with 25 genera and 31 species was the largest family and the genus Astragalus (Fabaceae) with 6 species was the largest genus in the region, respectively. The genera Tamarix with 5 species, Convolvolusand Nepeta each with 5 species, and Echinops, Eragrostis and Salvia each with 3 species are the other large genera in the flora of Faryab region.. Survey of the life form of the plants showed that 12/22%of the species were phanerophytes, 16/84% were chamaephytes, 30/64% were hemicryptophytes8/06% were geophytes and 32/24%were therophytes. The dominance of hemicryptophytes and therophytes (totally 62/88,) indicates the severe conditions of the area which is characteristics of the mountainous regions. Phytogeographically, 41/4%of the species belonged to the IranoTuranian region, 15/62%were Sahra Sandy and 34/4% belonged to the IranoTuranian and Sahra Sandy regions. and 8/58% belonged to the other regions. Also, 18 species were endemic for the flora of Iran, and, 9 species were rare.
