Abstract
In this consideration 36 aromatic plant species depending to labiate (Labiatae) family studied in Mazandaran province. The factors ecological studied in habitats aromatic plants were involved slope percentage, aspect, height, soil of texture, climate, yearly precpitation and temperature mean cover percentage, the best habitat with respect to abundance and denstity, vegetation types dispersion, companion plants of environmental conditions. Indicator plants of very cold mediterranean climate and over 3000 meter height are betony (Betonica nivea subsp mazandarana), motherwort (Leonurus cardiaca). Indicator plants of sub-dry cold climate (250-300mm precipitation) are hymenocrater (Hymenocrater calycinus), hedge nettle (Stahys turcomanica), desert rod (Eremostachys macrophylla), (E.labiosiformis), field- basil (Ziziphora teniur), cat thyme (Teucrium chamaedrys). Indicator plants of humid climate are hedge are hedge nettle (Stachys persica), calaminth (Calamintha grandiflora). The greatest abundence of plants occurred in cold mediteranean cllimate. Indicator plant olluvial and slopy foothill is catmint (Nepeta saccharrata). Indicator plants of dislocated and bare foothill in forsts and woodlands are wild marjoram (Origanum vulgare), hedge nettle (sachys setifera), horehound (Marrubium vulgare). Indicator plants of edge small rivers are calaminth (Calamintha grandiflora), catmint (Nepeta cataria). Indicator plants of unutilized drylands between forest and ragelands are hedge nettle (stachys byzanthina). Indicator plants of little saline soils are hedge netlle (Stachys inflata) and afghan silver sage (pervoskia abrotanoides). The plant species such as hedge netlle (S.byzanthina, S.lavandulifolia), Thyme (Thymusspp), Catthyme (Teucrium polium) are very abundantand betony (Betonica nivea subsp mazandarana), hymenocrater (H.calycinus. H.elegans), desertrod (E.macrophylla, E.labiosiformis), calaminth (Calamintha officinalis), hedge nettle (S.setifera) catmint (Nepeta cataria), field-basil (Ziziphora tenuior), catmint (Nepeta pungens) are rare plants species in Mazandaran.
