Pollen grain morphology and seed coat characters of 11 cultivars belonging to two species of genus Hibiscus (Family Malvaceae) namely H. esculentus (H. Abelmoschus) and H. sabdariffa were investigated. This study was carried out using light microscope (LM) and Scanning Electron Microscopy (SEM). Pollen morphology of this genus is fairly uniform. Generally radially symmetrical apolar, mostly spheroidal, pantoporate. Seed exomorphic characters revealed four types of ornamentations; reticulate, ocealate, foveolate and ruminate. Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) was employed to characterize those taxa. Thirty one bands of seed protein profiles have been constructed from the gel. The produced dendrograms were analyzed by STATISCA program using UPGMA clustering method showed a close affinity among the seven H. esculentus cultivars and the four H. sabdariffa cultivars.

This study presents the Mallophaga and Anoplura lice which affects farm animals (camels sheep and goats), a local area east of the Saudi Arabia of different ages, races, classes. Study the classification of lice was recorded as using the optical microscope and electronic scanning. The study shows scanning electron microscopy micro-structure of the species: Bovicola (Damalinia) ovis, Linognathus africanus and the study showed the installation of a portfolio of head lice, and the distribution of filament head, chest and abdomen, as shown over the centuries, the difference in the form of remote sensing and Swallows in thesexuallice, the first study in this area.
