Alien flora cultivated in Southern Africa represents a non-random subset of the global flora and this bias at the introduction stage largely contributes to patterns in geographic origin, phylogenetic composition and traits of the natural¬ized flora. The strong phylogenetic clustering of the naturalized cultivated flora is also, to a large extent, driven by introduction bias. Although functional traits explained little variation in naturalization success of cultivated plants, naturalization success was more likely for plants with intermediate seed mass and height and high specific leaf area. Thus, despite strong biases in which species have been introduced to Southern Africa, there are significant patterns in the species characteristics related to naturalization probability. Our quantification of introduction biases demonstrates that they are huge, and that accounting for it is important to avoid over- or under-emphasizing the characteristics of successfully naturalized alien plants.
