A bright, remarkable yellow color which belongs to the genus Glaucium Mill. it is known as "yellow horned poppy". It is a medicinal plant species used in the pharmaceutical industry as a source of the alkaloid glaucine. Species spread on the seaside, river valleys, sandy soils (0-50 m). As a result of morphological examination, the stem is 23-42 cm lenght, hairless, branched, whitish green; the leaves are thick, very green-matte. Flower buds are hairless or slightly acute, ovate -rectangular, acute, petals usually yellow. As a result of the morphological investigations, parallelism was observed between the obtained data and the Flora of Turkey. In addition, the spreading areas and description have been improved and the obtained data has been transformed into a table. At the end of the palynological investigation, pollen grains usually were spheroidal in shape and tricolpate aperture, ornamentation microecinate and microperforate. Seed features; reniform, that surfaces alveolate and faveolate was observed.A bright, remarkable yellow color which belongs to the genus Glaucium Mill. it is known as "yellow horned poppy".
