This article analyses species origins, dispersal, and island vegetation dynamics of the Kingdom of Tonga in the South Pacific. It demonstrates that species–area relationships are significant for all plant species and for ancient and modern introductions, and species richness shows significant relationships to maximum elevation for indigenous plants and modern introductions. In contrast, species richness does not correspond to patterns expected for species–isolation relationships with the nearest archipelagos of Samoa and Fiji. It concludes that plant dispersal spectra vary significantly according to island topography, geology,vegetation types, and plant species origins
