Abstract

The current study investigates the floristic aspects of the plant communities infested with the parasitic plant Cuscuta planiflora in the Riyadh Region, Saudi Arabia, including a list of plant species, duration of documented species, life-form spectra, and phytochorotype of the plant life. Floristically, the total number of the recorded flowering plant species in the present study is 116, belonging to 92 genera and 26 families. According to the plant duration, these species are 65 perennial species (56.03%), 50 annual species (43.10%), and only one species biennial of the total plant species. Asteraceae, Brassicaceae, Poaceae, Fabaceae and Caryophyllaceae are the main families being represented collectively by 75 species or approximately 64.66% of the total number of the recorded species. The recorded species are classified under 6 types of life-form according to the Raunkiær system (Raunkiær 1934) therophytes, chamaephytes, hemicryptophytes, phanerophytes, geophytes and parasite. The floristic analysis of the research region indicates that Saharo-Arabian (mono-regional with 26.72%), bi-regional species with 26.72% and plurioregional species with only species (0.86%). In addition, Irano-Turanian and Saharo-Arabian, Saharo-Sindian phytochoria possessed 16 and 21 plant species
