There are some issues with the Egyptian flora still need to be resolved. Therefore, it requires further intensive collections from all regions, accurate taxonomical studies, geographical distributions updating for some species because of many factors affected the plants existence in many areas as: climate, new constructions, reclamation of many lands and introduction of invasive species. This research highlights of thirty species that weren't gathered from particular phytogeographical regions and the existence of some of them hadn't been authenticated in Egypt. so, it confirms the existence of some species in specific phytogeographical areas of Egypt. It was based on herbarium records and some previous studies. The mentioned species in this research include nine species belonging to three families: Atractylis boulosii, Reichardia picroides, Juncus littoralis, Lolium rigidum, Lolium perenne, Lolium multillorum, Rostraria hispida, Lygeum spartum and Aegilops Iongissima. The current study also verified the existence of Rostraria hispida, which wasn't confirmed in Egypt.
