The present study deals with the analysis of the floristic composition including plant species, life span, lifeform spectra and chorological affinities of weeds associated with mango orchards in Ismailia Governorate. A total of 102 weed species (79 annuals, 21 perennials and 2 biennials) related to 85 genera and grouped in 30 families were recorded. Out of the total species, 23 species monocots and 79 species dicots were recorded. Poaceae, Asteraceae, Brasicaceae and Fabaceae were the most species-rich families representing collectively about 50% of the total species. Therophytes were the predominant life form and constituted 73.53% of the total flora, followed by hemicryptophytes (12.75%), geophytes (4.9%), chamaephytes (3.92%), nanophanerophytes (2.94%) and helophytes (1.96%). The chorological analysis of the surveyed flora revealed that the Mediterranean elements constituted the main bulk (41.18%) of the total flora of the area. The other major chorotypes were cosmopolitan (24.51%), pantropical (13.73%) and palaeotropical (7.84%). Saharo-Sindian chorotype comprised 20 species (19.6%) of the recorded flora, while the other chorotypes were either poorly represented by few number of species or absent. Comparison between the present floristic composition of mango orchards in Ismailia with similar relevant studies either in Ismailia or in adjacent areas were included.
