Abstract
This study is conducted on 18 species representing 6 genera belonging to Solanoideae (Solanaceae).  These genera are: Capsicum (2 spp.), Datura (3 spp.), Hyoscyamus (2 spp.), Lycium (2 spp.), Physalis (3 spp.) and Solanum (6 spp. (. The plant samples are collected from various floristic regions in Egypt. The study is done on the morphological characters of flowers, inflorescences, fruits and seeds. The results are recorded in the form of comparison between the examined plants. The results showed that the flowers solitary as in Physalis peruviana or in cymes inflorescences as in Hyoscyamus muticus. Calyx consists of 5 sepals as in Solanum nigrum or more as in Solanum lycopersicum; campanulate. They are tubular, cub-shaped or plate- shaped. Corolla rotate, funnel- shaped or stellate shaped; lobes 5 or more usually equal or unequal in length and size. Stamens epipetalous is in all the examined plants. The number of the stamens is as many as the lobes of corolla and it is alternate with them; 5 stamens as in Solanum nigrum or more than 5 as in Solanumlycopersicum; dehiscing longitudinally or by apical pores. Pollen grains spherical as in Physalis angulata or oblate as in Hyocyamus muticus. Tri-colporate in all the studied samples as in Hyoscymus muticus except Physalis angulata whichhas four apertures. The ovary has various shapes; ovate as in Capsicum annuum, oblong as in Hyoscymus muticus or globular as in Physalis peruviana; glabrous, hairy or spiny. Placentation either axile or free central. Fruit capsule as in Datura stramonium or berry Lycium shawii. Seeds shape ovate, reniform, oblong or globose, testa smooth, curly or hairy.
