•: We analysed the aquatic vegetation of 1354 tropical and temperate river sites.
•: MEM, multiple regression and pRDA were used to analyse the datasets.
•: Spatial and environmental variables were both significant driving factors.
•: Species richness (S) in tropical rivers was only driven by spatial factors.
•: In temperate rivers S was driven by both spatial and environmental variables.
