Aut Ecology, Ethnopharmacology, Ecomorphology Sclerorhachis leptoclada Boiss "Mastar" and Floristic Spectrum of Medicinal Plants in Ark (Birjand city)

Sclerorhachis leptoclada belongs to Asteraceae family is one of the most medicine vegetable in traditional medicine in Birjand. In many field observation duos to investigate of aut ecology, ethnopharmacology and ecomorphology of Sclorhachis leptoclada Boiss. aerial parts of plant in blooming were collected from Ark (1395-1396). Ethno pharmacological data and biological spectrum of medicinal plants were obtained from rural healers. Also, by selecting three points in the habitat and three heights in each position, morphological characteristics such as plant height, number of leaves, number of flowering stems, dry weight and tremor were evaluated at the flowering stage. Results showed that this natural plant was wild grew in sandy loam soil, Ec=8/18, PH=7, Plant flowers appeared in Jun and May falled in late of July. Biological spectrum was showed that 31 medicine plants were grow wild in this region belongs to Asteraceae (19/3%), Apiaceae (12/9%), Lamiaceae (16/1), and in terms of biophyte Therophytes with 13 species (93.41%), Geophytes with 11 species (48.35%), Had the largest number of species and mostly belonged to the Iranian-Turanian, Mediterranean (41.9%) European-Siberian, Mediterranean (19.3%) origin. The results also showed that with increasing altitude in all three selected locations in the habitat, the number of leaves, dry and wet weight and plant height decreased. Finally, the observed diversity can be related to the role of altitude and the genetic structure of the populations, which can also be considered as a kind of adaptation and physiological response of Mastar to environmental conditions.
