Abstract: The chromosome numbers of 31 taxa belonging to 14 families of angiosperms collected from different regions of Saudi Arabia are reported. These include first chromosome number reports for sixspecies: Anabasis setifera 2n=18, Cleome amblyocarpa 2n=20, Halopeplis perfoliata 2n=18, Lavandula coronopifolia 2n=42, Lycium shawii 2n=24 and Salvia deserti 2n=48. A new basicnumber and/or a new ploidy level is reported for two species: Asphodelus tenuifolius 2n=4x=52 and Heliotropium lasiocarpum 2n=4x=32. The chromosome numbers of the other 23 species arethe first reports from Saudi Arabian populations: Abrus precatorius 2n=22, Alhagi camelorum 2n=16+2B, Amaranthus spinosus 2n=34, Astragalus abyssinicus 2n=16, Bienertia cycloptera2n=18, Capparis spinosa 2n= 38, Chenopodium album 2n=54, C. ambrosioides 2n=32, C. ficifolium2n=18, C. glaucum 2n=18, C. murale 2n=18, Datura innoxia 2n=24, Halocnemum strobilaceum 2n=18, Leptadenia pyrotechnica 2n=22, Moltkiopsis ciliata 2n=12, Rumex dentatus 2n=40, Salvia aegyptiaca 2n=28, S. spinosa 2n=20, Senna alexandrina 2n=28, Sesuvium sesuvioides2n=16, Silene apetala2n=2 Withaniasomnifera2n=48andZygophyllumcoccineum2n=16.Karyotypeanalyses for six species, viz. Alhagi camelorum, Astragalus abyssinicus,Datura innoxia, Moltkiopsis ciliata, Sesuvium sesuvioides and Rumex dentatus are presented
