Three keys to 44 species belonging to the family Convolvulaceae in the flora of Egypt are prepared to facilitate the identification of those species, based on 72 characters. These keys were constructed using the DELTA key-generating programs. The first key was built using all characters and the second key was built using 56 characters (vegetative, floral and fruit characters). The first key is considered as main key and can be confirmed by the second key in the field. The third one was built using 16 characters (pollen grains, seed and cell wall characters) which are to be used to identify and confirm the specimen in the laboratory
