AB  - BACKGROUND AND AIMS: Hydrophytes generally exhibit highly acquisitive leaf 
      economics. However, a range of growth forms is evident, from small, free-floating 
      and rapidly growing Lemniden to large, broad-leaved Nymphaeiden, denoting 
      variability in adaptive strategies. Traits used to classify adaptive strategies 
      in terrestrial species, such as canopy height, are not applicable to hydrophytes. 
      We hypothesize that hydrophyte leaf size traits and economics exhibit sufficient 
      overlap with terrestrial species to allow a common classification of plant 
      functional types, sensu Grime's CSR theory. METHODS: Leaf morpho-functional 
      traits were measured for 61 species from 47 water bodies in lowland continental, 
      sub-alpine and alpine bioclimatic zones in southern Europe and compared against 
      the full leaf economics spectrum and leaf size range of terrestrial herbs, and 
      between hydrophyte growth forms. KEY RESULTS: Hydrophytes differed in the ranges 
      and mean values of traits compared with herbs, but principal components analysis 
      (PCA) demonstrated that both groups shared axes of trait variability: PCA1 
      encompassed size variation (area and mass), and PCA2 ranged from relatively 
      dense, carbon-rich leaves to nitrogen-rich leaves of high specific leaf area 
      (SLA). Most growth forms exhibited trait syndromes directly equivalent to herbs 
      classified as R adapted, although Nymphaeiden ranged between C and SR adaptation. 
      CONCLUSIONS: Our findings support the hypothesis that hydrophyte adaptive 
      strategy variation reflects fundamental trade-offs in economics and size that 
      govern all plants, and that hydrophyte adaptive strategies can be directly 
      compared with terrestrial species by combining leaf economics and size traits.
