ARTICLE INFO ABSTRACT Article No.: 031014138 In present research, comparative anatomical study was carried on eight Type : Research Ferula species in NE Iran. The specimens were collected during March- DOI: 10.15580/GJBS.2014.4.031014138 June 2010- 2012. After identification, the cross sections from the base of stem, mature leaves, petioles and mericarps were prepared, and then stained by differential staining. Internal structure of stems, leaves and petioles varied among the species due to the shape and type of Submitted: 10/03/2014 collenchymous tissue below the epidermis layer and sclerenchymous Published: 28/05/2014 strands above the phloem, the shape of vascular bundle, the position and number of secretory ducts and the type of mesophyll.
