We investigated on the appearance and structure of the seeds of Papaver somniferum L., P. setigerum DC., P. Rhoeas L. and P. orientate L. as follows; a) Appearance: There seeds are kidney-shaped with one end broader (an obtuseangle…hilum) than the other (an acuteangle…chalaza) and amarked notch in which are both the hilum and chalaza connected by a short raphe, but on P. Rhoeas, the raphe is not clearly. On the surface and colour as Table I. b) Inner structure: 1) Seed coat: There seeds are consist five layers as follows; 1 st layer: On P. somniferum, enormously broad cells with thin wave walls. On P. setigerum, with fine uneven on outer walls. On P. Rhoeas, inner cell walls jut out to outside, corresponding to the ribs of the seed. 2 nd layer: Thin walled cells containing sand or single crystalls of calcium oxalate. On P. orientale, it is thin layer and containing ratio of crystall is less than others. 3 rd layer: Thick walled fibrous cells, On P. somnifarum faint yellow, but on others, brownish yellow. 4 th layer: The thick walled cells are rectangular or spindle form at right-angle to 3 rd layer. On P. soniferum is faint yellow, but on thers are brownish yellow. 5 th layer: The cells with spiral or reticulation is rectangle, brownish yellow. 2) Albumen: Out side (epidermis) is 1 cell layer with cuticule, but inner side are parenchyma with aleuron grain and fatty oil. 3) Embryo: Characterless.
