(2008): Morphological and anatomical investigations on endemic Allium armenum BOISS. & KOTSCHY and Allium djimilense BOISS. EX REGEL (Alliaceae) species of East Anatolia. – Thaiszia – J. Bot. 18: 1-8. – ISSN 1210-0420. Abstract: In this study, Allium armenum BOISS. & KOTSCHY and Allium djimilense BOISS. EX REGEL both endemic of Turkey, were compared morphologically and anatomically. The results showed that the investigated species had typical morphological characters of sect. Codonoprasum Reichenb. and also that they could be distinguished from each other not only by their morphological but anatomical characters as well. Keywords: Allium, Anatomy, Morphology. Introduction The genus Allium L. consists of more than 750 species distributed across the Northern hemisphere (VAN RAAWSDONK and DE VRIES 1992; FRIESEN et al., 2006). According to Seçmen et al. (1998), there are 146 species of Allium in Turkey and the 35% of these species are endemic (Özhatay, 1986). The first knowledge about Allium species of Turkey was given by BOISSIER (1884). The studied species occur in East Anatolia and belong to the section Codonoprasum, the subgenus Allium of the genus Allium (DAVIS, 1984). The present study is based on some wild species of Allium which can be eaten as folk vegetable (BAYTOP, 1984). Any study on the investigated species has not been found
