Compare of anatomical & ontogenical characteristic of 1 species Plantago (Plantago lanceolata L.) at two regions of Ghaemshahr & Tehran

In this paper the explanatory structure of vegetative & generative organs of plantain spears (Plantago lanceolata) was compared at two regions of Ghaemshahr& Tehran with the use of cellular and histological methods. Microscope observations of vegetative organs show the common structure of dicotyledonous plants. The results proves that anatomical and ontogenical structures of the vegetative & generative organs of the plants at both regions are similar and some trivial differences of environmental & climatic conditions such as:number of ,hairs and fiber layers in stem and on pheloem cells is recognized more in Ghaemshah compared with Tehran also rsecretory & non-secretory hairs are distinguished on leaves in Ghaemshahr plants, which are rare in Tehran.
