Abstract
Glaucium taxa were investigated in terms of their morphological, palynological and phylogenetical characteristic. The results of this study show differences between the taxa in some of these characteristics, especially in micromorphology and formation of clades in phylogenetic trees based on the matK and ITS3-6 DNA sequence data. Based on the findings of the molecular analyses supported by morphological data (stem’s trichomes),the genus Glaucium of Turkey was divided into subsections Glabrousae and Pubescentae.
Highlights
Glaucium Mill., belonging to the family Papaveraceae, is represented by a total of 25 species worldwide, and especially distributed throughout Western, Northern and Eastern Asia, Europe, Northern Africa, and Australia
Glaucium is represented by a total of 10 taxa in Turkey, namely G. corniculatum (L) Rud. subsp. corniculatum; G. corniculatum (L) Rud. subsp. refractum (Nab.) Cullen; G. grandiflorum Boiss & Huet var. grandiflorum; G. grandiflorum Boiss. & Huet var. torquatum Cullen; G. grandiflorum var. haussknechtii (Bornm. & Fedde) Parsa; G. flavum Crantz; G. leiocarpum Boiss.; G. acutidentatum Hausskn. & Bornm.; G. cappadocicum Boiss. and G. secmenii Yıldırımlı, four (G. grandiflorum var. torquatum, G. acutidentatum, G. cappadocicum, G. secmenii) of which are endemic (Seçmen et al 1998; Yıldırımlı, 2012)
In a phytochemical study performed by Vorniceanu et al, 2004, on the species of Papaveraceae, including G. corniculatum and G. flavum, from which many alkaloids were isolated and identified

(horned poppy), belonging to the family Papaveraceae, is represented by a total of 25 species worldwide, and especially distributed throughout Western, Northern and Eastern Asia, Europe, Northern Africa, and Australia. Glaucium is represented by a total of 10 taxa in Turkey, namely G. corniculatum (L) Rud. subsp. Refractum (Nab.) Cullen; G. grandiflorum Boiss & Huet var. Mory (1979) classified 22 species belonging to the genus into two sections, namely Acropetale and Glaucium. A micro-macromorphological study on 18 Glaucium taxa was carried out by Gran and Sharifnia (2008) based on 28 qualitative and 37 quantitative characters.
